C.7.6.4b.1 Enhanced Contrast/Bolus Module Attribute Descriptions
C.7.6.4b.1.1 Contrast/Bolus Ingredient Opaque for X-Ray Equipment

Contrast/Bolus Ingredient Opaque (0018,9425) Attribute specifies the type of relative X-Ray absorption of the contrast/bolus ingredient, compared to the X-Ray absorption of water.

Enumerated Values:

YES

The contrast/bolus ingredient absorbs more X-Ray photons than water

NO

The contrast/bolus ingredient absorbs less X-Ray photons than water

Note

The Contrast/Bolus Ingredient Opaque (0018,9425) Attribute determines the sign of the gradient of X-Ray beam intensity from inside to outside the injected vessel, thus allowing optimal settings of the image processing applications (e.g., vessel edge detection, etc.), see Figure C.7.6.4b-1.

The relative gray level of the injected vessel with respect to the gray level of the water of Pixel Data (7FE0,0010) is determined by the Contrast/Bolus Ingredient Opaque (0018,9425) and by the Pixel Intensity Relationship Sign (0028,1041). For example, if the contrast/bolus ingredient is more radio graphically dense than water (i.e., YES), and the Pixel Intensity Relationship Sign (0028,1041) is -1, then the contrast/bolus ingredient is represented by higher values of Pixel Data than water.
