β¦ Synopsis
This overview takes a look at different correction techniques for Single Photon Emission Computed Tomography (SPECT). We discuss the influence of the detection system followed by the scatter and attenuation caused by the object of investigation. When possible we describe how the correction methods for the different physical effects can be incorporated in the reconstruction method, being either filtered backprojection or iterative reconstruction.

Aim: To compare the performance of low-energy (LE) and medium-energy (ME) collimators and the use of scatter correction on 123 I SPECT images as assessed by visual inspection and semi-quantitative analysis. Materials and methods: Both brain and heart/thorax phantoms were used to evaluate the effects
## Background: Attenuation artifact remains a substantial limitation to confident interpretation of images and reduces laboratory efficiency by requiring comparison of stress and rest image sets. attenuation-corrected stress-only imaging has the potential to ameliorate these limitations. ## Method
