Proton-CT - a novel diagnostic method for particle therapy

In the recent decades there has been a worldwide increase in the number of cancer patients treated with proton and carbon radiation therapy. Particle therapy as of today is based on pre-calculated dose plans for each patient. The applied dose plans are created from X-ray computed tomography (CT) images.

However, even the best CT does not allow a sufficiently precise prediction of the ion beam range. In order to exploit the full potential of particle therapy, the Bragg peak has to be located inside the tumor with a submilimeter precision. The proposed novel clinical proton-CT will provide such a precise range estimate online.

The pCT-prototype combines a tracker and a calorimeter in a single compact device simultaneously performing tracking, particle identification and energy/range measurements. Because of the extremely high granularity the device will be able to cope with a large amount of particles, thus providing a breakthrough in rate capabilities.
