The cabinet office has issued the above document endorsing open standards.

I think this is very exciting, as we can now use IHE open standards for specifying
1. PACS
2. RIS
3. Modalities.
application/pdfCabinet Office endorses Open Standards
PPN 3_11 Open Standards.pdf (23.2 k)


As we specify these in our requirements, we are more likely to see these included with the IT solutions available provided we move to an open market economy of IT systems procurement.

IHE standards for PACS (Based on our group document)

Specifying the IHE standards for PACS
1. PACS must be an Image Manager actor for PIR profile of IHE
Patient Information Reconcilliation (PIR) Profile: “PIR handles: unidentified/emergency patient, demographic information updates ( e.g patient name changes (marriage, etc.) , correction of mistakes, ID space mergers). Such changes are reliably propagated to all affected systems, which update all affected data. The result is a complete patient record.”

2. PACS must conform to Image Manager & Image Display actor for SWF profile of IHE
Scheduled Workflow Profile-- Scheduled Workflow establishes a seamless flow of information that supports efficient patient care workflow in a typical imaging encounter. It specifies transactions that maintain the consistency of patient information from registration through ordering, scheduling, imaging acquisition, storage and viewing.

3. PACS must conform to Image Manager & Image Display actors for Basic Image Display profile of IHE
Basic Image Review Profile:
"Compliant software must provide a predictable user interface and functionality sufficient to review images for the purpose of clinical decision-making by ordering physicians: display of grayscale and color images from any modality, visual navigation of the available series of images through the use of thumbnails, side-by-side comparison of at least two sets of images (with synchronized scroll, pan and zoom for cross-sectional modalities) annotation of laterality, orientation, and spatial localization, annotation of demographics, management and basic technique information for safe identification and usage simple measurements of linear distance and angle cine capability for images that involve cardiac motion (e.g., cardiac US, XA, 500 CT or MR)"

4. PACS must conform to Image Manager & Image Display actors of Consistent Presentation of Images Profile of IHE.
Consistent Presentation of Images Profile of IHE
“Consistent Presentation of Images maintains the consistency of presentation for grayscale images and their presentation state information (including user an notations, shutters, flip/rotate, display area, and zoom). It also defines a standard contrast curve, the Grayscale Standard Display Function, against which different types of display and hardcopy output devices can be calibrated. Thus it supports hardcopy, softcopy and mixed environments.”

5. PACS must conform to Secure Node/Secure application actor of Audit Trail & Node Authentication profile of IHE.

“The Audit Trail and Node Authentication (ATNA) Integration Profile establishes security measures which, together with the Security Policy and Procedures, provide patient information confidentiality, data integrity and user accountability.”

6. PACS must conform to XDS-I source & XDS/XDS-I consumer actors of Cross Enterprise document sharing profile of IHE.
Cross Enterprise document sharing for Imaging—XDS-I--- Sharing imaging documents between radiology departments, private physicians, clinics, long term care, acute care with different clinical IT systems—thus contributing to the development of an electronic patient record concept.


7. PACS must conform to Export Selector & Export Manager actors of Teaching Files & Clinical Trials Export Profile (TCE Profile) of IHE

The Teaching Files & Clinical Trials Export Profile TCE profile describes a method for using existing standards to simplify and standardise the export of key medical images for education, research, and publication.

8. PACS must conform to Image Manager Actor of Radiation Exposure monitoring profile of IHE

“Radiation Exposure Monitoring (REM) facilitates the collection and distribution of information about estimated patient radiation exposure resulting from imaging procedures. The REM Profile requires imaging modalities to export radiation exposure details in a standard format. Radiation reporting systems can either query for these "dose objects" periodically from an archive, or receive them directly from the modalities.”

9. PACS must conform to Image Manager & Image Display actors of Nuclear Medicine profile of IHE.

Nuclear Medicine Profile : The Nuclear Medicine profile is a set of specifications as to how NM systems (Gamma cameras etc) and PACS systems should interact when dealing with NM data. The primary focus deals with storage and display of such data on PACS systems.


10. PACS must conform to Image Manager & Image Display actors of Mammography Image profile of IHE.
Mammography Image Profile: Efficient mammography reading requires specific display quality, behavior, layout and annotation of images, as well as convenient comparison of prior with current images. The IHE Mammography Image Profile (IHE Mammo) was developed specifically to define the necessary mammography requirements.

IHE standards for RIS (based on our Group document)

APPENDIX 2
IHE Specifications for RIS
1. RIS must be an Department System Scheduler actor for PIR profile of IHE
Patient Information Reconcilliation (PIR) Profile: “PIR handles: unidentified/emergency patient, demographic information updates ( e.g patient name changes (marriage, etc.) , correction of mistakes, ID space mergers). Such changes are reliably propagated to all affected systems, which update all affected data. The result is a complete patient record.”

2. RIS must conform to Department System Scheduler actor for SWF profile of IHE
Scheduled Workflow Profile-- Scheduled Workflow establishes a seamless flow of information that supports efficient patient care workflow in a typical imaging encounter. It specifies transactions that maintain the consistency of patient information from registration through ordering, scheduling, imaging acquisition, storage and viewing.

IHE standards for modalities (based on our Group doc)

APPENDIX 3
IHE Specification of Acquisition Modalities
1. Modalities must conform to Acquisition Modality actor for SWF profile of IHE
Scheduled Workflow Profile-- Scheduled Workflow establishes a seamless flow of information that supports efficient patient care workflow in a typical imaging encounter. It specifies transactions that maintain the consistency of patient information from registration through ordering, scheduling, imaging acquisition, storage and viewing.

2. Modalities must conform to Acquisition Modality actor of Consistent Presentation of Images Profile of IHE.
Consistent Presentation of Images Profile of IHE
“Consistent Presentation of Images maintains the consistency of presentation for grayscale images and their presentation state information (including user an notations, shutters, flip/rotate, display area, and zoom). It also defines a standard contrast curve, the Grayscale Standard Display Function, against which different types of display and hardcopy output devices can be calibrated. Thus it supports hardcopy, softcopy and mixed environments.”


3. Nuclear Medicine modality must conform to Acquisition Modality actor of Nuclear Medicine profile of IHE.

Nuclear Medicine Profile : The Nuclear Medicine profile is a set of specifications as to how NM systems (Gamma cameras etc) and PACS systems should interact when dealing with NM data. The primary focus deals with storage and display of such data on PACS systems

4. Mammography modality (CR/FFDM) must conform to Acquisition Modality actor of Mammography Image profile of IHE.
Mammography Image Profile: Efficient mammography reading requires specific display quality, behavior, layout and annotation of images, as well as convenient comparison of prior with current images. The IHE Mammography Image Profile (IHE Mammo) was developed specifically to define the necessary mammography requirements.

5. Modalities must conform to Acquisition Modality Actor of Radiation Exposure monitoring profile of IHE
