The aim of this study is to evaluate the suitability crystalline scintillator LaCl3:Ce for possible use in hybrid medical imaging systems, such as PET/CT and SPECT/CT scanners. For purpose, a single crystal (10 × 10 mm3) was irradiated by X-rays within tube voltage range from 50 150 kVp, absolute efficiency (AE) measured experimentally. energy absorption (EAE), quantum detection (QDE), spectral...

Angular distributions of the 14–17 MeV g rays from the Li~p ,g) reaction at Ep5450, 402, and 80 keV were measured at 0°<u lab<135°, using a BGO detector and a 28-mg/cm 2 LiF target. The angular distributions at Ep5450 and 402 keV agree with the previous results by Mainsbridge; at Ep580 keV the ground-state transition is anisotropic on the order of 20%, confirming recent results by Chasteler et al.

This article is intended to provide an overview of various aspects of clinical PET/CT. These include discussions of: (i) Important areas of clinical application; (ii) Opportunities in clinical research; (iii) Scanner and operating-mode considerations (e.g. BGO vs. LSO, LYSO or GSO scanners, 2D vs. 3D imaging). (iv) Study-specific considerations (e.g. patient preparation and positioning issues, ...

combined pet/ct scanners now play a major role in medicine for in vivo imaging in oncology, cardiology, neurology, and psychiatry. as the performance of a scanner depends not only on the scintillating material but also on the scanner design, with regards to the advent of newer scanners, there is a need to optimize acquisition protocols as well as to compare scanner performances on an objective ...

This report describes the construction and performance characteristics of a device capable of making rapid serial measurement of rat brain radioactivity following the administration of a positron emitting isotope. Two bismuth germanate oxide (BGO) scintillation detectors in a coincidence detection circuit are used to achieve the necessary degree of collimation. Data from the device can be used ...

Bismuth germanate (BGO) was the preferred crystal for positron emission tomography (PET) scanners, but substituted with emergence of faster crystals. Improvements in silicon photomultipliers (SiPMs) and use fast high frequency readout make it possible to prompt Cherenkov BGO order boost achievable coincidence time resolution (CTR) significantly. The large fluctuations detected photon yield are ...
