For all procedures dose documentation provides information needed to estimate radiogenic ri

29、sk to the population. It also plays a role in general institutional quality assurance by providing data for performance validation against established RADIATION dose reference levels. Detailed documentation makes a significant contribution to clinical management of PATIENTS following those intervent

30、ional procedures that might induce tissue reactions. The transition from imaging on film to digital imaging opened the possibility of automatically recording dose and other data with the images. The Digital Imaging and Communications in Medicine (DICOM) protocol traditionally provides some relevant

31、facilities for doing this in image headers. This has had several limitations. The most obvious of these is the lack of a means for storing dose data without storing images. Thus, radioscopic data was seldom stored; and no dose data was stored if the images were not stored. Improving dose documentati

32、on was addressed jointly by the International Electrotechnical Commission (IEC) and the DICOM Standards Committee. Supplement 94 to the DICOM standard was approved in 2005 and incorporated since the 2006 edition of the standard. The DICOM standard now provides the technical format needed to store th

33、e entire description of the dose used to perform a single imaging procedure. This first edition of IEC 61910-1 replaces the Publicly Available Specification (PAS) and can become a companion document to IEC 60601-2-43 and IEC 60601-2-54. It defines the reporting of relevant RADIATION dose information

34、 and establishes conformance levels for dose documentation, to be referred to by requirements in the aforementioned equipment standards. The conformance levels represent a combination of increasing PATIENT risk and an increasing interest in quality assurance. The basic dose documentation conformance

35、 level is intended for X-RAY EQUIPMENT that produces dose levels below significant deterministic thresholds for all INTENDED USES. The extended dose documentation conformance level is intended for X-RAY EQUIPMENT used for procedures that could cause significant tissue reactions. The process resultin

36、g from this work is summarized as follows. Information is gathered into a radiation dose structured report (RDSR). This new object is designed to be stored in a picture archiving and communication system (PACS), in a medical informatics system, in a freestanding dose management workstation, or in th

37、e X-RAY EQUIPMENT itself. A performed procedure step (resulting in a single RDSR) is related to the RADIATION applied to a single PATIENT by a single piece of X-RAY EQUIPMENT in one session. The data structure permits the transfer of entire studies at once or the streaming of information per individ

38、ual IRRADIATION-EVENT. The Integrating the Healthcare Enterprise (IHE) Radiation Exposure Monitoring (REM) Profile describes an IT architecture for the creation, storage, analysis and distribution (including submission to centralized registries) of DICOM RDSR objects.

40、01-2-43:2010 or IEC 60601-2-54:2009. NOTE 1 The intent is to develop and publish similar documents for other X-ray imaging modalities capable of producing RDSRs. NOTE 2 This document does not impose specific requirements on the accuracy of the reported or displayed data. Existing standards or regula

41、tions can have applicable requirements for accuracy and precision. This standard provides specific units and quantities and prescribes data storage formats. NOTE 3 The data formats are specified such that the numerical uncertainty attributable to the format is likely to be small compared to other da

42、ta uncertainties. NOTE 4 This document does not present any requirements on the form of display of dose information to OPERATORS or other individuals. The objective of this International Standard is to specify the minimum dataset to be used for reporting dosimetric and related information associated

43、 with the production of projection RADIOLOGICAL IMAGES. NOTE 5 The data fields and report structure are intended to facilitate the collection of dosimetric data useful for: management of procedures delivering significant dose, facility quality programs, establishment of reference levels, education.

44、NOTE 6 A public structure facilitates data analysis by any appropriate individual or organization. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
