Appropriate energy window width for gamma camera [Persian]
Introduction: Scatter radiation is one of the major sources of error in nuclear medicine data processing. Different methods of scatter correction have been introduced in order to improve the quality of data. However the best method is to avoid recording of scatter photons in acquisition. The only difference between scattered and non-scattered photons is the energy. Pulse height analyzer i...
متن کاملjnet: a successor to gnet
After several years of hoping that more recent programs would allow his graph tool gnet to be quietly forgotten, the author has finally bowed to requests from many colleagues to resurrect the project. This paper reviews some aspects of the history of stratigraphic software and presents an early prototype of jnet, a successor to gnet written in Java. jnet is intended to offer similar facilities ...
متن کامل[Evaluation of exposure to ionizing radiation among gamma camera operators].
BACKGROUND Protection of nuclear medicine unit employees from hazards of the ionizing radiation is a crucial issue of radiation protection services. We aimed to assess the severity of the occupational radiation exposure of technicians performing scintigraphic examinations at the Nuclear Medicine Department, Central Teaching Hospital of Medical University in Lódz, where thousands of different di...

متن کاملPutting Successor Variety Stemming to Work
Stemming algorithms find canonical forms for inflected words, e. g. for declined nouns or conjugated verbs. Since such a unification of words with respect to gender, number, time, and case is a language-specific issue, stemming algorithms operationalize a set of linguistically motivated rules for the language in question. The most well-known rule-based algorithm for the English language is from...
