Image reconstruction in 2D SPECT with 180◦ acquisition
This work concerns 2D SPECT imaging with uniform attenuation in the activity region. In this paper, it is shown that exact and stable reconstruction does not require the data to be known over 360◦ as has been previously assumed. An angular range of 180◦ is sufficient in parallel-beam geometry. A reconstruction formula which uses only data on a half-turn is provided with implementation details. ...
متن کاملOptimisation of image acquisition and reconstruction of 111In-pentetrotide SPECT
The aim of this study is to optimise the acquisition and reconstruction for SPECT with 111 In-pentetrotide with the iterative reconstruction software OSEMS. For 111 In-pentetrotide SPECT, the uptake in the tumour is usually high compared to uptake in normal tissue. It may, however, be difficult to detect small tumours with the SPECT method because of high noise levels and the low spatial resolu...
متن کاملFiltering in SPECT Image Reconstruction
Single photon emission computed tomography (SPECT) imaging is widely implemented in nuclear medicine as its clinical role in the diagnosis and management of several diseases is, many times, very helpful (e.g., myocardium perfusion imaging). The quality of SPECT images are degraded by several factors such as noise because of the limited number of counts, attenuation, or scatter of photons. Image...
متن کاملImage Reconstruction in 3D Short-Scan SPECT
Physical factors such as photon attenuation degrade image quality and quantitative accuracy in single-photon emission computed tomography (SPECT). It is often considered (especially in situations with non-uniform attenuation and distance-dependent spatial resolution (DDSR)) that adequate compensation for the effects of these physical factors requires data acquired over 2 . However, as the analy...
متن کاملAttenuation Correction in SPECT during Image Reconstruction using an Inverse Monte Carlo Method: A Simulation Study
Introduction: The main goal of SPECT imaging is to determine activity distribution inside the organs of the body. However, due to photon attenuation, it is almost impossible to do a quantitative study. In this paper, we suggest a mathematical relationship between activity distribution and its corresponding projections using a transfer matrix. Monte Carlo simulation was used to find a precise tr...
