"Design and Construction of a Positron Emission Tomography (PET) Unit and
Medical Applications with the GEANT Detector simulation Package"
Measurement of our detector system's crosstalk: System consisted of
Hamamatsu cross-wired PSPMT and CAMAC and NIM crates. Test was done by
scanning the surface of the PSPMT by an LED. General response of the
system was examined.
Measurement of our detector's resolution: For CSI(Tl) crystals
(3mmx3mmx30mm). Test was done using 137Cs and 60Co.
Simulation of Positron Emission Tomography (PET) Coincidence Unit. System
kept the same as real PET Unit used for a 2-D image reconstruction.
Coincidece measurements with the PET Unit. Backprojection to 2-D image
from 1-D projections of 22Na positron source. Result: very satisfactory
for our system. Further studies are to be done.
Simulations for proton therapy. Curve relating the range of protons to
their initial energy was obtained.
Below is the 3-D and 2-D representations of the 2-D reconstruction
