Enabling accuracy in prostate cancer care

The Raypilot system minimizes the risk of injuring healthy surrounding tissue in SBRT treatment of prostate cancer. The system positions the tumour with high accuracy at a rate of 30 times per second. This allows clinicians to monitor prostate movements in 3D and in real-time. Raypilot is easily adapted to the existing workflow, offering clinics a cost-effective system that is implemented without difficulty.

treatment with the Raypilot System

Undetected prostate motion is always a risk in radiation treatment of prostate cancer. The Raypilot system shows, in real-time, the true deviation of the prostate during the treatment session. See the video clarifying the difference between a conventional treatment workflow and a treatment using Raypilot System.

“The reported significantly increased toxicity for SBRT vs standard IMRT was mostly urethra related. Having the possibility to identify the urethra using the Raypilot Hypocath gives us the opportunity to reduce the urethral dose without underdosing the tumour, thus delivering a safer treatment.”

Medical Physicist Denis Panizza, San Gerardo Hospital, Monza, Italy

“Raypilot Hypocath enables us to keep track of prostate motion during SBRT treatments where the precise dose to the target and strict tolerance to the surrounding organs is paramount.”

Professor Stefano Arcangeli, Head of Radiation Oncology, San Gerardo Hospital, Monza, Italy

”Raypilot is a game changer for our clinic. Being able to track tumour movements in real time reduces the margins and removes the uncertainty we previously felt about hypofractionation. It helps us treat more patients through hypofractionation. The results so far have been very promising.”

Professor Duncan McLaren, Consultant Clinical Oncologist, Edinburgh Cancer Centre, Western General Hospital, Scotland

”Very user-friendly system. Very easy to understand and supports us a lot in the standard workflow. This system has the potential to become a valuable asset when using SBRT protocols for treating prostate cancer.”

Professor Felix Sedlmayer, Department of Radiotherapy and Radio-Oncology, LKH Salzburg, Austria and Paracelsus Medical University, Salzburg, Austria

the raypilot system

The Raypilot System consists mainly of three parts: the Raypilot Hypocath which is placed in the prostate and urethra for localization and motion-tracking; the Raypilot Receiver, which is placed on any treatment couch; and the Raypilot Software, which warns the user when motion occurs in the region of interest outside of the predefined tolerances. In addition, there is the Raypilot Viewcath which is used during treatment planning.

The Raypilot System is portable and user friendly and fits well into a standard workflow. You can monitor the software from the treatment room as well as from the control room.

Raypilot Receiver

The Raypilot Receiver is placed directly on any linac table and fixed with standard index bars. The antennas recognize the signals sent from the Raypilot Hypocath 30 times/second. The plate is lightweight, and easy to carry and connect prior to treatment, with easy removal post-treatment.

Raypilot Hypocath

The Raypilot Hypocath is a temporary urinary catheter with an integrated transmitter. It continuously shows the exact real-time location of the prostate in 3D and outlines the urethra. It also has a function for patient identification. Designed as a Foley catheter with the electronics inside of a dedicated lumen, it can be inserted in a standard catheterization procedure without the need of surgical intervention.

Raypilot ViewCath

The Raypilot Viewcath resembles a Raypilot Hypocath without electronics and the transmission function. It is used in treatment planning, ensuring a safe and effective treatment.

Raypilot Software

The Raypilot Software interprets the data and presents the localization in 3D and in real-time with sub-millimetre accuracy. It is easy to learn and use. The target motion is displayed in lateral, longitudinal and vertical directions, and the user is alerted if motion occurs outside of the predefined tolerances.

Treatment process

Patient workflow – from start to finish

The Raypilot System keeps track of the prostate during patient set up and treatment. Motion monitoring in real-time enables you to safely minimize the margins. Predefined margins are chosen for the tolerance margins by the physician. When margins are exceeded during the treatment sessions the Raypilot System alerts the user and the treatment is stopped. Data from the treatment is stored and saved for the user to access and analyze.


The patient is assigned radiotheraphy treatment by his pyshican. The treatment monitoring of prostate motion is enabled by the Raypilot System.



During the planning session the Raypilot Viewcath is inserted to simulate the same situation as in the coming treatment with the Raypilot Hypocath.

CT is performed and bladder filling is done according to clinical routine. After the CT is done the Raypilot Viewcath is removed.

Outlining of the urethra is performed by the physician.



Patient is scheduled for treatment (generally 1-7 days wait).



Now the physician can perform a safe real-time control urethra-sparing treatment.

Patient arrives and the Raypilot Hyopcath is inserted.
The bladder is filled with same volume as planned – reproducibility of the bladder filling.
Patient treatment starts (15 min average treatment time*).

Raypilot keeps track of the prostate motion during patient set up and throughout the treatment.



Single shot treatment:
After finished treatment the Raypilot Hypocath is removed, and patient goes home.



Between the treatment sessions the patient goes home with the Raypilot Hypocath catheter and comes back for the next scheduled session.



After the last treatment session, The Raypilot Hypocath is removed. Individual follow-up depending on clinical routine.



Routine scheduled visits and follow up at the clinic according to local routine.
