Description
The feasibility of a PET prototype for online and in-situ dose deposition control in
hadrontherapy is under study within our group at the “Institut de Physique Nucléaire
de Lyon”: IPNL. This is a non conventional use of the PET techniques that would allow
a real time non invasive control of the execution of a given cancer treatment plan
with heavy charged ionizing particles beam. In practice, our experimental setup is a
somehow conventional PET scanner equipped with a transparent and fast beam hodoscope
detector. Time correlations between the arrivals of beam particles to the target and
prompt nuclear gamma rays detection as well as the annihilation photon detection from
produced β+ emitter isotopes are exploited for an online and real time 3-D
reconstruction. We will report on the measurement performed with our prototype beam
hodoscope that has the ability of :
• high counting rate , up to 10^8 particles per second
• high transversal coordinates measurements, 250 μm
• high time stamp resolution, below 1ns
