Title: Real-time Imaging of prompt gammas in proton therapy using improved Electron Tracking Compton Camera (ETCC)
Abstract content We have developed an Electron-Tracking Compton Camera (ETCC) for medical imaging due to its wide energy dynamic range (200 - 1500keV) and abilities of background rejection and clear imaging using the tracking information of the recoil electron. Thus this camera has a potential of developing the new reagents for molecular imaging. Until now we have carried out several imaging reagent studies such as : (1) F-18-FDG (511keV) and I-131-MIBG (364keV) for double clinical tracer imaging, (2) Zn-65(1116keV),Mn-54, Fe-59 in mouse for high energy gamma emitting RI imaging. In addition, ETCC can image continuum spectral gamma-rays by removing background particle using dE/dx of the track. ETCC has a potential of real-time monitoring of the Bragg peak location by detecting prompt gammas. We successfully obtained the images of both 511keV and continuum high energy gamma rays (800-2000keV) from the water target irradiated by 140MeV proton (Kurosawa, Cur. Apl. Phys, 12 (2012), pp. 364). In 2013 we have completed a 30cm cube ETCC to catch gamma-rays, of which tracking efficiency was improved with 10 times. It enables to select the Compton event contained in TPC using only the energy loss rate of the track with distinguishing it from all backgrounds. Eventually its sensitivity is improved by a factor of 100. A similar imaging test for prompt gammas using 140MeV proton beam was recently carried out, of which intensity was increased more 10 times than previous experiment. Here I present new performance of the improved ETCC and the results of the beam test.
