RayPilot® transmitter
- soon without need for surgical intervention*

RayPilot® transmitter

The RayPilot transmitter is placed in the ROI and the motion of the transmitter is continuously detected in 30 Hz.

In addition to motion detection it also has an included microchip for automatic patient identification. R&D work is ongoing to include an in-situ dosimeter.

The transmitter is inserted prior to the first treatment and removed after the last treatment session which means that there are no foreign objects left in the body that potentially could interfere with MRI.

The RayPilot® Transmitter has been in clinical use since 2010 in different fractionation schedules;

– from conventional protocols (40 fractions) to extreme hypofractionated protocols (5 fractions).


RayPilot® HypoCath® is a demanded evolution of the original RayPilot® Transmitter. It has the same proven electronics in a new package. By designing it as a Foley catheter and have the electronics inside a dedicated lumen, it can be inserted in a standardized catheterisation procedure without need of surgical intervention.

RayPilot® HypoCath™

The goal with the design is to:
  • track motion of the transmitter and the surrounding urethra and prostate
  • offer insertion and removal as a standardised catheter procedure 
  • keep the HypoCath® catheter throughout the whole SBRT treatment 
  • maintain urinary function
  • reproduce the bladder filling from the planning to the daily treatment
  • minimize the time between insertion and treatment

* The dosimetry feature and the HypoCath® is work in progress


One transmitter for all sessions

Non permanent

Insertion of Transmitter similar to gold fiducial implantation and methods used in brachy therapy and interventional radiology

Transmitter with fixation tines

Good signal quality also in obese patients

No foreign objects left in body - no interference during MRI follow-up
