RayPilot® is CE-certified for continuos prostate tracking. By knowing the exact position of the cancerous organ at any moment, the treatment can be focused on the tumor and healthy surrounding tissue can be avoided. For prostate cancer treatment there are publications showing unpredictable tumor motion over one cm during ongoing radiotherapy sessions. Such movements cannot be detected with the conventional radiotherapy techniques used today.

A precise treatment

The functionality of RayPilot® is similar to a GPS system by means that a target is localized with given coordinates. The system communicates with an implanted transmitter that is located in the ROI to be treated. The transmitter sends signals to a sensor plate 30 times per second and the position is presented in the software. The advanced technology and calculation algorithms give sub millimeter accuracy of target locations.

The system consists of the RayPilot receiving system which is placed on any existing treatment couch, the RayPilot transmitter that is placed in the ROI, and the RayPilot software.

Initially, the system is used in treatment of prostate cancer where a precise and safe localization will increase the treatment quality. It can also speed up and improve the patient set-up time for a more effective use of the radiotherapy equipment.

An automatic gating solution is available for use with Varian’s Clinac® iX linear accelerators and Trilogy® systems.
