System Specifications
1.10 Image Receptor Support Device
Image Receptor Support Device Contains sensors for accessory detection and a
3-cell automatic exposure control detector,
movable to seven positions in 1.7 cm incre-
ments. The Image Receptor Support Device
limits x-ray transmission to no more than 0.1
mR for the maximum exposure. Complies with
21 CFR, section 1020.31, and meets the 1
mGy per exposure as defined by IEC 601-1-3,
section 29.207.2.
1.11 C-arm Functions
All C-arm functions Vertical drive, rotation, compression function,
compression release, light field, etc., are
simultaneously operable. Compression up and
down are also controlled by footswitches.
