Method and system for verification of different types of beam limiting devices in a linear accelerator utilized for radiotherapy

摘要

A method and system for verifying an accessory beam limiting device position for a radiotherapy treatment session are described. Included in a system aspect is a radiotherapy treatment device (20), the radiotherapy treatment device (20) including an accessory holder (24). A beam limiting device (22) for establishing a treatment area, the beam limiting device (22) held in the accessory holder (24), is also included, along with a first controller (18) for controlling the radiotherapy device (20) and performing a treatment plan. A second controller (10) positions the beam limiting device (22) according to the treatment plan, wherein performance of the treatment plan by the first controller (18) depends on provision of an accessory code to the first controller (18). The accessory code includes a resistor-pair combination value.
