As a radiation oncologist at Premier Cancer Centers in Dallas, TX, Dr. Rajiv “Raj” Dahiya works with a broad range of advanced radiation technologies. Dr. Rajiv “Raj” Dahiya treats many of his patients with the CyberKnife M6, a robotic radiosurgery system.
Developed by the Accuray company, the CyberKnife M6 offers a noninvasive alternative to surgery for many cancer patients. It uses image guidance technology to specifically pinpoint a patient's tumor, which the system tracks throughout the course of treatment. This leads to precisely targeted radiation delivery with strong tumor-coverage rates and optimized conformal dosing, which maximizes effectiveness while minimizing secondary damage.
The treatment starts with preliminary imaging, which the radiation oncologist uses to plan the delivery of a dose. This plan serves as an instruction to the CyberKnife's computer-facilitated robot, which positions the machine in those locations determined to be most effective. The robot delivers the necessary radiation over the course of up to five sessions, each of which lasts 30 to 90 minutes.
The CyberKnife system has the capacity to treat tumors throughout the body and does not require any rigid positioning systems. Patients remain comfortably positioned throughout the treatment process and most often experience only minimal side effects, which typically resolve themselves in less than 48 hours.
