Proton therapy allows to decrease the risk of side effects during treatment to 12%, compared to
conventional radiotherapy.[1]
In this therapy most of the energy is deposited in a defined region where the tumor is located (known as
the Bragg peak).With multiple Bragg peaks of protons, it’s possible to control the deposited dose through all the volume
of the tumor. However, a small angle difference at the beam source increases the probability to hit the healthy tissues
and organs.
To provide high spatial resolution and precise measurement of the proton beam position, an architecture
based on three layers of semiconductor pixel detectors is proposed to increase beam control and reduce
ghost tracks. Additionally, fast electronics and data acquisition technology must be used to record all the
data accurately.
Studying materials and configurations for the pixels to monitor the beam, minimizing the side effects and
maintaining the proton therapy treatment.
