The reference point moves with the gantry in such systems. Appropriate estimates of skin dose must account ... (Adapted and reprinted with permission of the National Council on Radiation Protection ...

These systems utilize a gantry that is able to rotate 360° to deliver radiation along with an integrated cone-beam CT and an onboard x-ray imager to coordinate accurate patient positioning.

The outer ring is the gantry on which the linear accelerator (linac) that produces the radiation for treatment is mounted. The linac gantry can rotate completely around. In the center is the bed ...

Radiation dose using this method can be high ... In helical continuous CT scanning, the patient's table moves through the gantry as it rotates. The pitch of the scan is the ratio of table motion ...
