IEC 60601-2-11:2013 applies to the basic safety and essential performance of gamma beam therapy equipment, including multi-source stereotactic radiotherapy equipment. This particular standard of the 60601 series, establishes requirements to be complied with by manufacturers in the design and construction of gamma beam therapy equipment. It states tolerance limits beyond which interlocks must prevent, interrupt or terminate irradiation in order to avoid an unsafe condition. Type tests which are performed by the manufacturer, or site tests, which are not necessarily performed by the manufacturer, are specified for each requirement. It does not attempt to define the optimum performance requirements for a gamma beam therapy equipment for use in radiotherapy. Its purpose is to identify those features of design which are regarded at the present time as essential for the safe operation of such equipment. It places limits on the degradation of equipment performance at which it can be presumed that a fault condition applies, e.g. a component failure, and where an interlock then operates to prevent continued operation. This third edition cancels and replaces the second edition of IEC 60601-2-11 published in 1997 and its Amendment 1:2004. This edition constitutes a technical revision which brings this standard in line with the third edition of IEC 60601-1 and its collateral standards.

This International Standard is applicable to the performance of dosimeters with vented ionization chambers and/or semiconductor detectors as used in X-ray diagnostic imaging. The object of this standard is to establish requirements for a satisfactory level of performance for diagnostic dosimeters, and to standardize the methods for the determination of compliance with this level of performance. This standard is not concerned with the safety aspects of dosimeters. The diagnostic dosimeters covered by this standard are not intended for use in the patient environment and, therefore, the requirements for electrical safety applying to them are contained in IEC 61010-1. This second edition cancels and replaces the first edition and constitutes a technical revision.

The object of this standard is to define a consistent set of coordinate systems for use throughout the process of teleradiotherapy, to define the marking of scales (where provided), to define the movements of equipment used in this process, and to facilitate computer control when used. This second edition cancels and replaces the first edition, published in 1996, amendment 1, published in 2000 and amendment 2, published in 2007. This edition constitutes a technical revision to include imager and focus coordinate systems in Subclause 3.12. Beyond this Subclause, changes were only introduced where needed to include the above coordinate systems.

IEC 60731:2011 specifies the performance requirements of radiotherapy dosimeters, intended for the measurement of absorbed dose to water or air kerma (and their rates and spatial distributions) in photon, electron, proton or heavy ion radiation fields as used in radiotherapy. The dose monitoring systems incorporated in radiotherapy treatment machines are not covered by this standard, neither are the re-entrant ionization chambers used for brachytherapy source calibration and constancy check devices. IEC 60731:2011 is applicable to the following types of dosimeter:

1) in vivo skin surface or intracavitary measurements of dose on patients.
2) in vivo skin surface or intracavitary measurements of dose on patients.
b) reference-class dosimeters normally used for the calibration of field-class dosimeters;
c) scanning-class dosimeters normally used for relative dose distribution measurements with a scanning system such as an automatic water phantom.
The object of this standard is:
- to establish requirements for a satisfactory level of performance for radiotherapy dosimeters;
- to standardize methods for the determination of compliance with this level of performance.
Three levels of performance are specified:
- a lower level of performance applying to field-class dosimeters;
- a higher level of performance applying to reference-class dosimeters;
- a specific level of performance applying to scanning-class dosimeters.
This third edition cancels and replaces the second edition published in 1997 and its Amendment 1 (2002) and constitutes a technical revision. The technical modifications versus the second edition of this standard concerns performance requirements of radiotherapy dosimeters intended for the measurement of absorbed dose to water or air kerma in heavy ion radiation fields and scanning-class dosimeters normally used for relative dose distribution measurements with a scanning system such as an automatic water phantom.

It includes the requirements for accuracy and reproducibility of performance to the extent that these are related to radiation quality and the quantity of ionizing radiation produced and thus must be considered as aspects of safety. This second edition cancels and replaces the first edition of IEC 60601-2-8. This edition constitutes a technical revision which brings this standard in line with the third edition of IEC 60601-1 and its collateral standards.

IEC 60601-2-1:2009 applies to the basic safety and essential performance of electron accelerators in the range 1 MeV to 50 MeV, used for treatment of patients. This particular standard establishes requirements to be complied with by manufacturers in the design and construction of electron accelerators for use in radiotherapy; it does not attempt to define their optimum performance requirements. Its purpose is to identify those features of design that are regarded, at the present time, as essential for the safe operation of such medical electrical equipment. It places limits on the degradation of medical electrical equipment performance beyond which it can be presumed that a fault condition exists and where an interlock then operates to prevent continued operation of the me equipment. This third edition cancels and replaces the second edition published in 1998 and its Amendment 1 (2002). It constitutes a technical revision. This third edition addresses the following issues not covered in previous editions:
- alignment with the new relevant collateral standards;
- new technologies in radiotherapy, including stereotactic radiosurgery (SRS) and stereotactic radiotherapy (SRT), intensity modulated radiotherapy (IMRT), electronic imaging devices (e.g. EPID) and moving beam radiotherapy (dynamic therapy).

IEC 62467-1:2009 specifies the performance and some related constructional requirements of well-type ionization chambers and associated measurement apparatus, intended for the determination of a quantity, such as air kerma strength or reference air kerma rate in photon radiation fields or absorbed dose to water at a depth, in photon and beta radiation fields used in brachytherapy, after appropriate calibration for a given type of source. IEC 62467-1:2009 covers the techniques for the quantification of the quantity appropriate for the brachytherapy source under consideration. This quantity may be air kerma strength or reference air kerma rate at 1 m, or absorbed dose to water at a depth (e.g. 2 mm or 5 mm). Measurement of these quantities may be accomplished by a variety of well-type ionization chambers or systems currently available for this purpose. This standard applies to products intended for low dose rate, high dose rate, intravascular, both photon and beta, brachytherapy measurements. It does not apply to instruments for nuclear medicine applications. The application of the standard is limited to instruments that incorporate well-type ionization chambers as detectors. The intended use is the measurement of the output of radioactive, encapsulated sources for intracavitary (insertion into body cavities) or interstitial (insertion into body tissue) applications. The object of IEC 62467-1:2009 is
a) to establish requirements for a satisfactory level of performance for well-type chamber systems, and
b) to standardize the methods for the determination of compliance with this level of performance.
IEC 62467-1:2009 is not concerned with the safety aspects of well-type chamber systems. The well-type chamber systems covered by this standard are not intended for use in patient environment. The electrical safety of well-type chamber systems is covered in IEC 61010-1. The operation of the electrometer measuring system is covered in IEC 60731.

Specifies the performance requirements of instruments as used in the non-invasive measurement of X-ray tube voltage up to 150 kV and the relevant compliance tests. Describes the method for calibration and gives guidance for estimating the uncertainty in measurements performed under conditions different from those during calibration. This standard is not concerned with the safety aspect of such instruments. The requirements for electrical safety applying to them are contained in IEC 61010-1. This consolidated version consists of the first edition (2002) and its amendment 1 (2008). Therefore, no need to order amendment in addition to this publication.

Specifies the performance requirements of instruments as used in the non-invasive measurement of X-ray tube voltage up to 150 kV and the relevant compliance tests. Describes the method for calibration and gives guidance for estimating the uncertainty in measurements performed under conditions different from those during calibration.

IEC/TR 60977:2008 applies to medical electron accelerators when used, for therapy purposes, in human medical practice. This technical report applies to medical electron accelerators which deliver a radiation beam of either X-radiation or electron radiation with nominal energies in the range 1 MeV to 50 MeV at maximum absorbed dose rates between 0,001 Gy s-1 and 1 Gy s-1 at 1 m from the radiation source and at normal treatment distances between 50 cm and 200 cm from the radiation source. This second edition cancels and replaces the first edition published in 1989 and its Amendment 1 (2000). It constitutes a technical revision. This second edition likewise follows on the issue of a second edition to the disclosure standard IEC 60976 in 2007. It includes the addition of performance guidelines relating to several relatively new technologies introduced within the last few years, including dynamic beam delivery techniques, such as moving beam radiotherapy, intensity modulated radiation therapy (IMRT), image guided radiotherapy (IGRT), and programmable wedge fields (PWF). Also included are stereotactic radiotherapy (SRT)/stereotactic radiosurgery (SRS) and the use of certain electronic imaging devices (EIDs).

Specifies terminology and test methods for declaring the characteristics of positron emission tomographs. Positron emission tomographs detect the annihilation radiation of positron emitting radionuclides by coincidence detection. It is intended that the test methods be carried out by the manufacturers, thereby enabling them to declare the characteristics of positron emission tomographs. So, the specifications given in the accompanying documents shall be in accordance with this standard.

IEC 60601-2-29:2008 establishes requirements to be complied with by manufacturers in the design and construction of radiotherapy simulators; it does not attempt to define their optimum performance requirements. Its purpose is to identify those features of design that are regarded, at the present time, as essential for the safe operation of such medical electrical equipment. It places limits on the degradation of medical electrical equipment performance beyond which it can be presumed that a fault condition exists, for example a component failure, and where an interlock then operates to prevent continued operation of the medical electrical equipment. This third edition cancels and replaces the second edition published in 1999. This edition constitutes a technical revision, which brings this standard in line with the third edition of IEC 60601-1 and its collateral standards.

Applies to equipment and data related to the process of teleradiotherapy, including patient image data used in relation with radiotherapy treatment planning systems, radiotherapy simulators, isocentric gamma beam therapy equipment, isocentric medical electron accelerators, and non-isocentric equipment when relevant. The object of this standard is to define a consistent set of coordinate systems for use throughout the process of teleradiotherapy, to define the marking of scales (where provided), to define the movements of equipment used in this process, and to facilitate computer control when used.

Applies to medical electron accelerators when used, for therapy purposes, in human medical practice. This standard applies to medical electron accelerators which deliver a radiation beam of either X-radiation or electron radiation with nominal energies in the range 1 MeV to 50 MeV at maximum absorbed dose rates between 0,001 Gy s-1 and 1 Gy s-1 at 1 m from the radiation source and at normal treatment distances between 50 cm and 200 cm from the radiation source. The present standard describes measurements and test procedures to be performed by the manufacturer at the design and construction stage of a medical electron accelerator but does not specify acceptance tests to be performed after installation at the purchaser's site. The accompanying report, IEC 60977, however, does suggest that many of the test procedures are appropriate for acceptance tests. The measurement conditions described in the present standard differ from those previously in use. This applies particularly to the phantom position for measurements and the measurement of distances from the isocentre. These new conditions should be substituted for and not be added to previous methods. This standard specifies test procedures for the determination and disclosure of functional performance characteristics, knowledge of which is deemed necessary for proper application and use of a medical electron accelerator and which are to be declared in the accompanying documents together with the greatest deviation or variation to be expected under specific conditions in normal use. A format for presentation of functional performance values is given in Annex A. It is recognized that inaccuracies in the test methods must be allowed for when assessing performance. However, it was not felt to be advisable to combine the errors into an overall performance tolerance but to keep them separate in the expectation that more accurate test methods will be evolved. It is not intended that this standard should in any way inhibit the future development of new designs of equipment which may have operating modes and parameters different from those described herein, provided that such equipment achieves equivalent levels of performance for the treatment of patients. Except where otherwise stated this standard assumes that the medical electron accelerators have an isocentric gantry. Where the equipment is non-isocentric, the description of performance and test methods may need to be suitably adapted. This second edition cancels and replaces the first edition published in 1989. It constitutes a technical revision. This second edition includes the addition of performance standards and test methods relating to the following new technologies: - dynamic beam delivery techniques, such as moving beam radiotherapy, intensity-modulated radiation therapy (IMRT), image-guided radiotherapy (IGRT) and programmable wedge fields; - stereotactic radiotherapy (SRT) / stereotactic radiosurgery (SRS); - use of electronic imaging devices. This standard, together with IEC TR 60977, should be read in conjunction with IEC 60601-2-1.

This technical report covers the routine testing of radionuclide calibrators used in nuclear medicine. Such devices utilise ionization chambers of the well type (directly coupled to an appropriate electronic circuitry (IEC 61145)) and a direct readout in units of ACTIVITY. Requirements and specific methods to determine performance parameters are described in IEC 61303 and IEC 61145. These methods are primarily designed for acceptance testing.

This International Standard applies to test procedures which, for the determination of characteristics of systems or components of medical diagnostic X-ray equipment, require well-defined radiation conditions. Except for mammography, this standard does not apply to conditions where discontinuities in radiation absorption of elements are deliberately used to modify properties of the radiation beam (for example by rare earth filters). This standard deals with methods for generating radiation beams with radiation conditions which can be used under test conditions typically found in test laboratories or in manufacturing facilities for the determination of characteristics of medical diagnostic X-ray equipment. Examples of such radiation qualities are radiation beams emerging through the filtration from the X-ray source assembly. radiation conditions represent the more general case, where scattered radiation emerges from an exit surface of a patient or a phantom. This requires a well defined geometrical arrangement.

This technical report is valid for positron emission tomographs utilizing stationary or moving detectors in a circular arrangement. It is not valid for SPECT-systems operated in coincidence mode. In the framework of quality control, this technical report describes test methods suitable for the purpose of routine testing. Methods used for acceptance testing are described in IEC 61675-1:1998.

Applies to the design and manufacture and some installation aspects of a record and verify system (RVS) for use in radiotherapy in human medical practice that a) provides, defines, or displays treatment machine set up data; imports data either through input by the operator or directly from other devices, b) may control the ability of that equipment to operate; c) records data of all treatment sessions; and d) is intended to be: 1) for normal use, under the authority of appropriately licensed or qualified persons, by operators having the required skills and training; 2) maintained in accordance with the recommendations given in the instructions for use; and 3) used within the environmental and electrical supply conditions specified in the technical description.

IEC 61675-2:1998 specifies terminology and test methods for describing the characteristics of Anger type rotational gamma camera single photon emission computed tomographs equipped with parallel hole collimators. As these systems are based on Anger type gamma cameras this part of IEC 61675 shall be used in conjunction with IEC 60789. These systems consist of a gantry system, single or multiple detector heads and a computer system together with acquisition, recording, and display devices. The test methods specified in this part of IEC 61675 have been selected to reflect as much as possible the clinical use of Anger type rotational gamma camera single photon emission computed tomographs. It is intended that the test methods be carried out by manufacturers, thereby enabling them to describe the characteristics of gamma camera single photon emission computed tomographs systems on a common basis. No test has been specified to characterize the uniformity of reconstructed images because all methods known so far will mostly reflect the noise of the image.

Since IEC 61675-2 was first published in 1998, further developments of single photon computer tomographs allow some of the tomographs to be operated in coincidence detection mode as well. To comply with this trend, this amendment describes test conditions in concordance with the test methods established for dedicated PET systems.

The use of afterloading equipment for brachytherapy purposes may expose patients to danger if the equipment fails to deliver the required dose to the patient, or if the equipment design does not satisfy standards of electrical and mechanical safety. The equipment may also cause danger to persons in the vicinity if the equipment itself fails to contain the radioactive source(s) adequately within the storage container(s) and/or if there are inadequacies in the design of the treatment room. This Particular Standard establishes requirements to be complied with by manufacturers in the design and construction of afterloading equipment for use in temporary brachytherapy procedures. Its purpose is to identify those features of design that are regarded, at the present time, as essential for the safe operation of such equipment. It places limits on the degradation of equipment performance beyond which it can be presumed that a fault condition exists and where an interlock then operates to return the radioactive source(s) to the storage container(s) and afterwards to prevent continued operation of the equipment.
