Health informatics - Medical Data Interchange: HIS/RIS-PACS and HIS/RIS - Modality Interface

1.1   This European Prestandard specifies information objects and services to be used when transferring information between medical imaging modalities and information systems in a healthcare environment.
1.2   This European Prestandard does not specify the information or usage domains of particular modalities or information systems as these vary according to local and national practices.
1.3   This European Prestandard only applies to information sent between a modality and an information system in the form of a worklist, in response to a request from that modality.  It provides:
   - a description of the content of the messages that transfer the worklist information and
   - a communication mechanism to transfer these messages.
1.4   This European Prestandard is applicable only to character-based (i.e. alphanumeric) information.  It does not apply to information presented as images or graphics.
1.5   This European Prestandard does not cover information objects and services to be used when transferring administrative, request, report and diagnostic service plan information between  DISs (of imaging departments) to or from HIS.  This is covered by  CEN/TC 251/PT3-022.

This European Prestandard (ENV) was approved by CEN on 19 October 2000 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

INTRODUCTION
The use of digital medical image acquisition systems (modalities) is growing rapidly. New developments in
information technologies support the inclusion of images in information systems (IS). The introduction of
systems to handle digital medical images (PACS) throughout the hospitals requires integration of the
modalities with the PACS and with the existing information systems. These developments urgently require a
standard for the interoperability between the imaging systems and the existing information systems in the
hospital.
Firstly, digital medical images need to be coupled with the related information entities (such as patient and
imaging procedure) as maintained in various information systems in the hospital. This coupling needs to be
established at the moment of image acquisition.
Second, the logistic aspects of performing imaging examinations, such as scheduling and tracking, is
currently supported by information systems without any interaction with the modality. In future the logistic
process needs to be supported by the Modality and the IS together.
The scenario can be globally described as follows:
- Before a medical image can be acquired by a modality, the administrative system needs to make the
relevant administrative and technical information available to the modality operator, e.g.:
- Patient information (name, ID number, date of birth, etc.)
- Scheduling information (procedure to be performed, special requirements, etc.)
This information will normally be held by other ISs within or outside the imaging department. It is
normally made available by sending a worklist to the modality
- When the image has been acquired by the modality, it needs to be coupled with the related patient
information such as patient and type of imaging procedure performed. The image and related data
will then be stored locally or sent to the PACS or other information system.
- When the work is complete, administrative information (e.g. procedure performed, comments on the
acquisition process) and technical information (e.g. equipment settings) will be sent from the
modality to one or more of the information systems.
These and other related requirements can be fulfilled by the realisation of an interface between the modality
and the Information System (IS) environment. The IS comprises all information systems that support any
activities in the hospital, such as care, diagnosis, logistics, and administration.
This European Prestandard defines such a standard interface by reference to DICOM Supplement 10 “Basic
Worklist Management (Modality Worklist Management SOP Class)” (NEMA PS 3 Supplement 10) which
results from joint work of CEN/TC251/PT020 and ACR-NEMA Working Group VI.
This European Prestandard explicitly does not cover the integration of DISs (of imaging departments) with
HIS. This is covered by CEN/TC 251/PT3-022 Mandate MO21/BC/CEN/93/17.9 FWD (CEN/TC 251/PT3-
022).
1. SCOPE
1.1 This European Prestandard specifies information objects and services to be used when transferring
information between medical imaging modalities and information systems in a healthcare environment.
1.2 This European Prestandard does not specify the information or usage domains of particular modalities
or information systems as these vary according to local and national practices.
1.3 This European Prestandard only applies to information sent between a modality and an information
system in the form of a worklist, in response to a request from that modality. It provides:
- a description of the content of the messages that transfer the worklist information and
- a communication mechanism to transfer these messages.
1.4 This European Prestandard is applicable only to character-based (i.e. alphanumeric) information. It
does not apply to information presented as images or graphics.
1.5 This European Prestandard does not cover information objects and services to be used when
transferring administrative, request, report and diagnostic service plan information between DISs (of
imaging departments) to or from HIS. This is covered by CEN/TC 251/PT3-022.
2. NORMATIVE REFERENCES
This European Prestandard incorporates by dated or undated reference, provisions from other publications.
These normative references are cited at the appropriate places in the text and the publications are listed

A.2 Scope and Field of Application for the Basic Worklist Management Service Class
The Basic Worklist Management Supplement to the DICOM Standard specifies the Basic Worklist
Management Service Class, which supports the exchange of any type of worklist from one Application Entity
(AE) to another AE. The Basic Worklist Management Service Class contains the Modality Worklist SOP
Class, which supports the transfer of the Modality Worklist from the Information System (IS) to the
Modality.
A.3 Basic Worklist Management Service Class
The Basic Worklist Management Supplement to the DICOM Standard specifies a DICOM Basic Worklist
Management Service Class, which defines an application-level class-of-service which facilitates the transfer
of worklists.
A worklist is the structure to present information related to a particular set of tasks. It specifies particular
details for each task. The information may support the selection of the task to be performed first and may
support the performance of that task. One example is the worklist used to present information about
scheduled imaging p
