Abstract
Computerized tomography is a method of radiological diagnosis that allows us to arrive at a cross-sectional view of a region of the body under examination using X-rays. SPECT is a high-level 3D imaging of scintigraphy taken for the treatment of conditions such as radioactive materials, thyroid diseases, cancers, tumors, inflammatory diseases, etc. The fact that SPECT and CT are in one system gives spatial and pathological correlation of abnormal metabolic activity. This ensures that images are recorded together at the most efficient level and images are obtained from both systems with a single review.
In this study, SPECT / CT simulations were performed for cylindrical voxel phantoms with near-real content using the GATE (PET & SPECT simulator library) created by the GEANT4 simulation software developed by the European Center for Nuclear Research (CERN). In the installations created in the virtual environment, activity differences, displacement and curtain effects of the tissues were investigated. Analyses were made with the ROOT software to obtain sinograms and dose curves. When the obtained data were analysed statistically, the results of these types of SPECT / CT imaging were found to be significant differences and the results were revealed.
