Abstract
Abstract
Tc-99m and I-123 are radionuclides commonly used for
diagnostic examination in nuclear medicine. Detection of the
scattered photons by the Compton interactions in the photopeak
energy window is a factor affecting the image quality. DEW and TEW
scatter correction methods are used to improve the image quality
degrade by Compton scattered photons. In the study, planar and SPECT
images of sphere, rod and cardiac phantom containing different
activities were acquired with a gamma camera system. DEW/TEW
corrected and uncorrected images for Tc-99m/I-123 were evaluated
qualitatively and quantitatively. Both for planar and SPECT images,
the DEW and TEW scatter correction methods were found to improve the
image quality at varying rates.
