Our research group
is presently carrying out research on applying new computer technology
to enhancing the resolution of medical gamma cameras used for human
diagnostic imaging. Specifically, we are working with a group at
the School of Physics at the University of Melbourne to model and
then to build a prototype of a device to increase the spatial resolution
of a medical gamma camera from the present 5 -8 mm to about 2-3 mm.
This will allow individual blood vessels in the brain to be imaged
in real time.
This same research will be applied to the detectors used in SPECT and PET medical
imaging. In these cases our development will permit reduced gamma ray "pile-up" and
will therefore permit significant lower radiation exposure to the patients.
