What are the most important mechanical aspects of proper positioning?
The simulator must be able to match positioning parameters consistent with the common motions of typical treatment units. Gantry rotation, Source-to-axis (SAD) adjustment, collimator rotation, image intensifier movement and table movements must all match the treatment unit. Mechanical tolerances, anti-collision systems, and readout consistencies must also be maintained. Simulator performance should be a precise match to the treatment unit with the only exception being that the simulator delivers low-energy diagnostic X-rays instead of high-energy radiation.
