Research Abstract |
We investigated the feasibility of fast data acquisition in heavy ion CT(IonCT) technique with an X-ray intensifying screen-charged coupled device(CCD) camera system. Weuseda high quality Electron Multiplying CCD(EMCCD) camera, which drastically reduced data acquisition time. We also useda parallel-plate ionization chamber upstream of anobject to monitor the time variation inheavy ion beam intensity from a synchrotronaccelerator and to perform beam intensity correction for all EMCCD images. We demonstrated that an electron density phantom consisting of six rods was successfully reconstructed in only 10min for 256 projections with a relative electron density resolution of 1%.
