Effects of crystal pixel size and collimator geometry on the performance of a pixelated crystal gamma-camera using Monte Carlo simulation.
Dedicated γ-cameras based on pixelated scintillators have long been used for breast tumor imaging. Intercrystal scattering (ICS) increases the background counting rate and degrades the image quality when small crystal pixels are used. Because of the small size of applied collimators, scattered radiation and septal penetration are high, and therefore collimator characteristics must be carefully ...

هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
The Influence of Crystal Size and Material on Intercrystal Scattering and Parallax in PET Block Detectors: A Monte Carlo Study
Introduction: In this study, we utilized the MCNP4C Monte Carlo code to quantitatively evaluate the influence of crystal size and material on intercrystal scatter and parallax effects. Materials and Methods: For each of the 5 selected crystals (BGO, LSO, LYSO, LuAP, GSO), transport of 511 keV photons originating from a point source and incident on the central cry...
متن کاملon the relationship between using discourse markers and the quality of expository and argumentative academic writing of iranian english majors
the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
