Some scintillation camera manufactures adhere to standard code of performance specification established by National Electric Manufactures Association (NEMA). Items such as differential and integral uniformity, spatial resolution energy resolution, etc. are all calculated with reproducible methodology that allows the user reliable technique for creation of these standards to avoid any lack of cl...

This study presents the comparison of the cumulative distribution of tropospheric scintillation models in order to see which model suits the best with the measured one. About six different models were compared and studied with the measured one. The scintillation data were taken from January 2011 till December 2011 which totals up to a 12 month period. This paper also presents the percentage fra...

This study aimed to assess the knowledge of nuclear medicine technologists (NMTs) in radiation emergency preparedness and response operations their willingness participate such operations. A survey was developed for this purpose distributed NMTs Saudi Arabia. Sixty participants responded with a rate 63.31%. Based on overall protection related response, can perform detection, population monitori...

Gallium-67 images have generally suffered from poor quality because of difficulty in properly collimating the multiple photopeaks released by the radionuclide. A comparison of the spatial resolution and septal penetration characteristics of two collimators we currently use for Ga-67 imaging-with a scintillation camera system equipped with single photopeak analyzersis presented. Results show tha...

Two types of distortions are produced by the gamma camera. One is nonuniform sensitivity re sponse over the detecting area. The second is spatial distortion; that is, the displacement from their true positions of the xand y-coordinates of a scintilla tion. This component of camera image distortion arises in the resolution and transfer of the xand y-coordinates of a scintillation and results in ...

Telepathology is becoming easier to implement in most pathology departments. In fact e-mail image transmit can be done from almost any pathologist as a simplistic telepathology system. We tried to develop a way to improve capabilities of communication among pathologists with the idea that the system should be affordable for everybody. We took the premise that any pathology department would have...
