Varian OBI (kV)

Specs on kV imaging system

Varian G242 tube
14 degree anode
.4 and .8 mm focal spot

kvD amorphous silicon detector

Layer is 1.8 cm below the scatter grid
40x30 cm panel at isocenter

the kV arms are defined by anatomy, shoulder, arm etc
Defaults for the arms are 100 cm source to isocenter, 50 for the panel

kVp maxes out at 140, says it goes up to 150 but really 140.

OUT is out of the way, retract is fully retracted. But to access cabinets has to be OUT but not fully retracted (back).
