Abstract Details

2012, Master of Science in Engineering, University of Akron, Biomedical Engineering.
Nuclear medicine images have limited spatial resolution because of the limitations in the radiation detector and the associated electronics. Due to these limitations, the image of a point source of radiation is blurred. The degree of this blurring is called the point spread function of a gamma camera, the imaging device used in nuclear medicine. The aim of this study is to develop a technique to increase the spatial resolution and contrast by improving the point spread function of the system. The basic idea of the proposed technique is to build a special collimator plate that replaces the conventional gamma camera collimator. Develop an algorithm that processes the images obtained with a gamma camera with the special collimator plate to improve the point spread function of the gamma camera. The images with the proposed gamma camera collimator plate method will be compared to the conventional collimator method. Qualitatively the comparison is done by visually inspecting the images. Quantitative comparisons are done by the significant differences in their modulation transfer function. Both comparisons indicate the proposed method is better than the conventional method.
