When high-energy radiation is used to kill cancer cells in radiation therapy, it also directly affects healthy skin cells. This can cause skin detachment, itching, or injury. In most cases, skin problems caused by radiation therapy are not serious and will improve a few weeks after treatment. But skin changes such as itching during this period may be very uncomfortable. The infection or ulcer caused by radiotherapy on the skin may also cause significant pain, which may lead to interruption or suspension of radiotherapy. If skin reactions become a problem, radiation therapy doctors may need to change the patient's radiation dose or schedule until the condition improves.

Varian's latest Respiratory Gating for Scanners (RGSC) system collects a patient's respiratory waveform curve through infrared reflection, then transmits respiratory information to the Computed Tomography (CT) system and automatically synchronizes it with the patient's radiation therapy planning program. After completing the plan design, Simply apply the patient's respiratory curve recorded by RGSC on the treatment preparation interface to use TrueBeam linear accelerator for respiratory gating treatment....
