introduction: one of the major problems in the development of nuclear medicine images is the presence of noise. the noise level in nuclear medicine images is usually reduced by the analysis of imaging data in a fourier transform environment. the main drawback of this environment belongs to low signal to noise ratio in high frequencies because removing noise frequencies may remove data and times...
هدف اصلی این رساله معرفی، تبیین روش عملکرد و بررسی نوآوری های ممکن دستگاهی با نام "فانتوم تطبیقی کنترل کیفی" است که برای انجام آزمایش های کنترل کیفی سیستم های تصویر برداری پزشکی هسته ای طراحی و ساخته شده است. فانتوم تطبیقی کنترل کیفی یک فانتوم قابل کنترل بوسیله کامپیوتر بوده که می تواند یک چشمه رادیواکتیو را در میدان دید سیستم تصویر برداری پزشکی هسته ای در مسیر مشخص و معین قابل برنامه ریزی توسط...

as described in the first part of this article, evidence based medicine (ebm) is a growing part of medical practice which emphasizes on the best evidence. finding this evidence by formulating an answerable question and searching strategies were described in the first part of this review. in this part, appraising the retrieved article (with the main focus on the diagnostic studies) and applying ...
BACKGROUND This paper is the first in a series of invited perspectives by four pioneers of Nuclear Medicine imaging and physics. A medical physicist and a Nuclear Medicine clinical specialist each take a backward look and a forward look at the contributions of Medical Physics to Nuclear Medicine. DISCUSSION Contributions of Medical Physics are presented from the early discovery of radioactivi...
