We aim at improving the quantitative assessment of the severity of myocardial perfusion defects in cardiac SPECT imaging. The idea of a numerical heart template is utilized, which enables a patient specific measurement of defect severity as opposed to the more traditional population-based approaches. Using NCAT we developed three male thorax phantoms with different orientations and sizes of the left...
Patient motion artifacts created in cardiac SPECT imaging can lead to misinterpretation of the images, resulting in false diagnoses. This simulation study proposes a new technique for patient motion correction (MC), where we utilize a modified template projection/reconstruction (TPR) algorithm to perform a voxel-by-voxel correction to the original image. Using NCAT, we developed two female phantoms...
