In this paper source-detector solid angle calculation has been studied by Monte Carlo method, and a computer program is represented. Since most experimental works in nuclear physics are done by using of cylindrical detectors, the solid angle of this type of detector is calculated for various sources. The source in various shapes of a point, cylinder, sphere, or rectangle, may be located in any ...
OBJECTIVE To compare the diagnostic performance of a new dedicated ultrafast solid-state cardiac camera (Discovery NM 530c [DNM]) with standard dual detector cameras (S-SPECT) in myocardial perfusion imaging. The primary goal was a per-patient analysis of diagnostic performance of the DNM using S-SPECT as the reference standard. METHODS AND RESULTS In total, 168 patients underwent one-day Tc-...
We report the use of Heat transfer Module of COMSOL multiphysics and a technique based on Infrared Photothermal Radiometry to study the heat transfer of a homogeneous and isotropic solid material excited by a periodic laser beam on the front side of the sample, and an infrared detector on the rear side in order to obtain the evolution of the temperature difference with the exposure time. Also, ...
