Attribute Name Tag Comment
X-Ray Receptor Type (0018,9420) DIGITAL_DETECTOR is used in this scenario.
Positioner Type (0018,1508) CARM is used in this scenario.
C-arm Positioner Tabletop Relationship (0018,9474) YES is necessary in this scenario.

In case of X-Ray Receptor Type (0018,9420) equals “IMG_INTENSIFIER”, there are some limitations that prevent the calculations described on this scenario:

As a consequence, in case of image intensifier it is impossible to relate the position of the pixels of the stored area to the isocenter reference system.
