چکیده
This paper considers Scintimammography (SM) imaging using two different image acquisition/formation methods: Low Energy High Resolution (LEHR) collimator and a Modified Uniformly Redundant Array (MURA) coded aperture (CA) systems. Using Monte Carlo simulation, the effectiveness and performance of both systems were evaluated by quantitative comparison of lesion contrast and Full-Width-Half-Maximum under a variety of clinical imaging situations. The results from the CA studies suggest that for the particular geometry studied, the MURA-CA gives comparable performance compared to using a LEHR collimator.

Evaluation of the performance of parallel-hole collimator for high resolution small animal SPECT: A Monte Carlo study
Introduction: Image quality and accuracy of in vivo activity quantification in SPECT are affected by collimator penetration and scatter components, especially in high energy imaging. These phenomena highly depend on the collimator characteristic and photon energy. The presence of penetrated and scattered photons from collimator in SPECT images degrades spatial resolution, contr...
متن کاملBremsstrahlung imaging from the liver using the Monte Carlo simulation
Introduction: Most beta and gamma radiation radioisotopes used for treatment are not suitable for imaging. The bremsstrahlung images on a conventional gamma camera helped to localize the radionuclide within and outside of the lesion. Secondary scattering of gamma rays of higher energy and bremsstrahlung causes contamination in the energy window and reducing the contrast and resolution of the im...
متن کاملInvestigation of Collimator Influential Parameter on SPECT Image Quality: a Monte Carlo Study
Background: Obtaining high quality images in Single Photon Emission Tomography (SPECT) device  is the most important goal in nuclear medicine. Because if image quality is low, the possibility of making a mistake in diagnosing and treating the patient will rise. Studying effective factors in spatial resolution of imaging systems is thus deemed to be vital. One of the most important factors in S...

Introduction:In an ideal parallel-hole collimator, thickness of septal material should be sufficient to stop more than 95% of incident photons. However, some photons pass the septa without interaction or experience scattering before they reach the detector. In this study, we determined different contribution of collimator responses consist of geometrical response, septal penetr...

Introduction: Myocardial perfusion SPECTby 99mTc-Sestamibi and 99mTc-Tetrofosmin radiopharmaceuticals usually presents a false significant increase in the radiotracer uptake in the inferior myocardium due to the uptake in organs such as liver, bowel, stomach and biliary system. The present study evaluated a suitable Slit angle for differentiating extra-car...
