DICOM Conformance Statement for Cedara CR
Contents
1. The scope of this DICOM Conformance Statement is to facilitate integration between Cedara CR Console Manager and other DICOM products The Conformance Statement should be read and understood in conjunction with the DICOM Standard DICOM by itself does not guarantee 5 Revision 2 0 Cedara CR Console Manager 1 1 DICOM Conformance Statement interoperability The Conformance Statement does however facilitate a first level comparison for interoperability between different applications supporting compatible DICOM functionality This Conformance Statement is not supposed to replace validation with other DICOM equipment to ensure proper exchange of intended information In fact the user should be aware of the following important issues The comparison of different Conformance Statements is just the first step towards assessing interconnectivity and interoperability between the product and other DICOM conformant equipment Test procedures should be defined and executed to validate the required level of interoperability with specific compatible DICOM equipment as established by the healthcare facility 1 4 Terms And Definitions Informal definitions are provided for the following terms used in this Conformance Statement The DICOM Standard is the authoritative source for formal definitions of these terms Abstract Syntax the information agreed to be exchanged between applications generally equivalent to a Service Object Pair SOP
