Hybrid positron emission and computed tomography systems quality control testing and implementation of the shielding unit account

Positron emission tomography is the one of the system which in used medicine. Computed tomography often used of the imaging techniques in radiology. PET images with CT data combined into simultaneously in a single image to obtain information on the patient combined with positron emission and computed tomography has become possible. In this study, Department of Nuclear Medicine, Hacettepe University, PET-CT unit formed the walls and doors of the room shielding calculations were performed. According to calculations, According to calculations, the thickness of the wall was built, required by using radioisotopes, the accuracy was checked with a Geiger Muller device. In the Department of Nuclear Medicine of Hacettepe University, GE brand with Discovery ST model PET-CT device was used. During installing the unit quality control tests and calibrations were done Acceptance testing of PET (NEMA NU 2-2001) and performance tests were explanid to described.
