Position sensitivity of the first SmartPET HPGe detector

چکیده
In this paper we discuss the Smart Positron Emission Tomography (PET) imaging system being developed by the University of Liverpool in conjunction with CCLRC Daresbury Laboratory. We describe the motivation for the development of a semiconductorbased PET system and the advantages it will offer over current tomographs. Details of the detectors and associated electronics are discussed and results of high precision scans are presented. Analysis of this scan data has facilitated full characterization of the detector response function and calibration of the three-dimensional position sensitivity. This work presents the analysis of the depth sensitivity of the detector. r 2006 Elsevier B.V. All rights reserved. PACS: 07.85. m; 29.40.Gx; 87.62.+n

High purity germanium (HPGe) detectors are ubiquitous in nuclear physics experiments and are also used in numerous low radioactive background detectors. The effect of the position of Co and Cs point sources on the shape of spectra were studied with Monte Carlo and HPGe detector measurements. We briefly confirm previous work on the position dependence of relative heights of peaks. Spectra taken ...

One important factor in using an High Purity Germanium (HPGe) detector is its efficiency that highly depends on the geometry and absorption factors, so that when the configuration of source-detector geometry is changed, the detector efficiency must be re-measured. The best way of determining the efficiency of a detector is measuring the efficiency of standard sources. But considering the fact t...

One of the most important instruments in gamma ray spectroscopy is HPGe detector. Concept of virtual point detector was considered for Ge(Li) detector. On the basis of this concept, there is a point inside a Ge detector that can be regarded as a fictitious point detector hosting all the interactions. If there is really a point whose response can be considered similar to that of the whole real b...
