Comparative Study of the Gamma Camera and Rectilinear Scanner for Detection of Superficial Lesions
Abstract
A study has been made comparing the performance of the gamma camera and rectilinear scanner in detecting the presence of a superficial brain lesion. Experiments were conducted to compare resolution and sensitivity of both devices; they showed that at the usual distance of a superficial lesion from the collimators of the devices, the gamma camera had superior resolution and sensitivity. Both-patient and phantom studies were performed, which demonstrated the superiority of the gamma camera, and it is suggested that if superficial lesions are suspected, the gamma camera should be used for imaging these lesions.
