TID 4122 CAD Common Image Properties Entry Template

Each instance of the CAD Common Image Properties Entry template contains selected attributes for a set of parallel contiguous equally spaced slices (with identical properties) from which CAD findings are derived.

10 > CONTAINS CODE EV (112226, DCM, “Spacing between slices”) 1 M Shall be computed from the Image Position (Patient) (0020,0032) projected onto the normal to the Image Orientation (Patient) (0020,0037); may or may not be the same as the Spacing Between Slices (0018,0088) if present. UNITS = EV (mm, UCUM, “millimeter”)
11 > CONTAINS CODE EV (112228, SRT, “Recumbent Patient Position with respect to gravity”) 1 MC Required if Patient Position (0018,5100) is present in the image instances and has a value. Shall be derived from Patient Position (0018,5100) in the Image Instances. DCID (6206) Recumbent Patient Orientation for Colon CAD
