RayPilot® used for hypofractionated prostate treatments at the Helsinki University Central Hospital

The use of RayPilot® has started at the Helsinki University Central Hospital (HUCH) in Finland. RayPilot is installed for real-time electromagnetic prostate localisation on a brand new Elekta Versa HD™ linear accelerator also equipped with the Brainlab ExacTrac® system.

The patients will undergo an every other day hypofractionated protocol of 5 fractions where internal prostate motion surveillance is made by RayPilot and where the beam will be gated when prostate motion exceeds a predefined margin.

Chief physicist Mikko Tenhunen from HUCH states: 

– With the RayPilot system we are able to start the real-time motion monitoring of prostate together with the hypofractionated protocol. The RayPilot system seems to be easy to use and set-up of the system does not increase the time slot needed for treatment remarkably.

The RayPilot that is an add on to existing linear accelerators consists of mainly three parts, an implantable transmitter, a receiving sensor plate to be placed on top of any couch and software that localise the transmitter and thus the ROI 30 times a second. A complete RayPilot installation is normally done in a couple of hours.

– We are very happy to also have the largest university hospital in Finland up and running. It is exciting that they directly use the RayPilot in order to enable hypofractionated protocols that will save a lot of time which is beneficial for the clinic, the health care system and for the patient says Charlotta Tilk, Sales- and marketing manager at Micropos Medical.

Helsinki University Central Hospital is the largest university hospital in Finland with 10 linear accelerators from Varian and Elekta and more than 1300 new prostate cancer cases in the Helsinki region yearly.

About Micropos Medical AB (publ):

Micropos Medical AB (publ) (www.micropos.se) is a Swedish company that has developed the RayPilot® system, which is an electromagnetic positioning and real time tracking system for a fast and objective set-up and for continuous positioning during radiotherapy. A precise and safe localization of the tumor can dramatically improve the outcome of the treatment, particularly for hypofractionated protocols. The RayPilot® system consists mainly of three parts; one transmitter that is placed close by the tumor, a receiving system that is placed directly on the treatment couchtop and software that continuously shows the precise tumor location, and hence where to focus the linac beam. RayPilot® has a unique gating solution qualified and compatible for use with Varian’s Clinac® iX linear accelerators and Trilogy® systems. During 2015 Micropos will release an upcoming RayPilot® transmitter for positioning, in-situ dosimetry and automatic patient identification. RayPilot® is CE certified for prostate use.
