Investigation of The New Generation Detector System Using in Medical Image
Abstract
Mammography
and standard breast imaging devices in the hospital are not enough an accurate
diagnosis of breast cancer especially over the 40 years old and overweight
women. The spatial resolution of the scintillation detector system is a highly
important parameter for nuclear medical imaging. GATE simulation program, based
on GEANT4, is used for the investigation of the SPECT system with different
scintillations which are commonly used in the imaging device. Medical images
for the point source are obtained by ImageJ software and image properties such
as spatial resolution and mean grey values are compared for the several
scintillations. This research shows that the spatial resolution value for
GAGG(Ce), relatively new scintillation material, is very close to SrI which is
one of the expensive scintillators. NaI, LaBr and CeBr are extremely
hygroscopic and not easy to be packaging with a specific shape. Therefore,
GAGG(Ce) are found to be encouraging result to be a part of the novel medical
image device. This study also shows how important using collimator in front of
the scintillation material for obtaining a meaningful image and how improved
the image quality using the array scintillator instead of one single block.
There is not any research regarding medical imaging obtained by GAGG(Ce)
scintillation material in GEANT4 simulation, so this research data presented
are the first of their kind.
