The usage of this module is recommended to give the necessary conditions to enable the calculations of this scenario.
Table FFF.2.5-3 XA/XRF ACQUISITION MODULE Recommendations
|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:
The position of the projection of the isocenter on the intensifier active area is undefined;
The Field of View Origin (0018,7030) cannot be related to the physical area of the receptor because the Intensifier TLHC is undefined.
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.
