Modeling of the tomographic weights usually incorporates angle of view, decay and attenuation. A usual assumption is that the gamma camera is a long way from the object, this leads to the approximation that the angle of view subtending the front of the collimator tube is the same as that subtending the back (Weir & Green, 1994). However, if the distance between camera and subject is small then ...

National Research Nuclear University, Moscow Engineering Physics Institute, Russia A full-body gamma-camera based on SiPM readout is currently under development as a part of MEPHI R activity supported in the framework of Russian Megagrants program. A goal of this development is a fast upgrade of existing medical equipment with minor changes in a system design and construction in order to combin...

A 256-element mercuric iodide (Hg12) detector array has been developed which is intended for use as an intraoperative gamma camera (IOGC). The camera is specifically designed for use in imaging gamma-emitting radiopharmaceuticals (such as 99m-Tc labeled Sestamibi) incorporated into brain tumors in the intraoperative surgical environment. The system is intended to improve the success of tumor re...

— The wide field optical camera with high temporal resolution for the continuous monitoring of the sky in order to catch the initial stages of GRBs is described. PACS 95.55.Cs – Ground-based ultraviolet, optical and infrared telescopes. PACS 98.70.Rz – gamma-ray sources; gamma-ray bursts. Gamma-ray bursts (GRBs) are one of the most powerful transient events in the Universe which are probably re...

For the next generation of MeV range gamma-ray telescopes, position sensitive calorimeters based on a monolithic scintillator coupled to pixelated photodetector could be an important building block. In this paper, we present optimization reconstruction algorithms using machine learning, for detector 51×51×10mm3 CeBr3 crystal. that purpose, used automated test bench and collimated radioactive so...

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...
