Radiotherapy with the CyberKnife® robotic treatment device is based on a small linear accelerator on the robot's arm that produces photon radiation. Similar radiation is also produced by traditional radiotherapy devices, but the method of administration of radiotherapy is different with the CyberKnife® device.
CyberKnife's robotic arm is highly mobile, allowing the treatment beams to be focused on the patient in a way that saves healthy organs and tissues better than traditional treatment devices.
The robot of the treatment device is very precise. It is capable of hitting a moving object with an accuracy of less than 0.5 millimeters. Accuracy and the free orientation of the treatment beams also enable treatment in difficult-to-locate treatment sites. At the same time, it is possible to use higher dosages, which reduces the number of treatments.
Patient-friendliness is also enhanced by CyberKnife's treatment monitoring. The device finds its treatment target by comparing the X-rays taken from the patient during the treatment planning phase with the images taken during the treatment. If the patient or treatment site moves during treatment, the equipment will detect this and the error will be corrected automatically.
When the treatment machine is able to monitor the patient's position, the accuracy of the treatment is maintained, even if the position changes slightly.
