Introduction: Thyroid cancer is at the ninth from ten of common malignant cancer. A man has higher risk to get Thyroid cancer that a woman has. This organ is lain near human neck. The use of radioactive I-131, I-123 and Tc-99m for diagnosis of thyroid cancer has a risk where other organs around Thyroid will accept dose of radiation. One of the risks is large dose which is accep...

background: in myocardial perfusion spect imaging, images are degraded by photon attenuation, the distance-dependent collimator, detector response and photons scatter. filters greatly affect quality of nuclear medicine images materials and methods: a phantom simulating heart left ventricle was built. about 1mci of 99mtc was injected into the phantom. images were taken from this phantom. some fi...

introduction quality control is an important phenomenon in nuclear medicine imaging. a jaszczak spect phantom provides consistent performance information for any spect or pet system. this article describes the simulation of a jaszczak phantom and creating an executable phantom file for comparing assessment of spect cameras using simind monte carlo simulation program which is well-established fo...
