This study describes and validates a new method for automatic segmentation of left
ventricular mass (LVM) in myocardial perfusion SPECT (MPS) images. This is important for …

Background By gating image acquisition in myocardial perfusion SPECT (MPS) to ECG, left
ventricular (LV) volumes and function can be determined. Several previous studies have …

Background The performance of left ventricular (LV) functional assessment using gated
myocardial perfusion SPECT (MPS) relies on the accuracy of segmentation. Current …

Left ventricular (LV) segmentation, including accurate assignment of LV contours, is
essential for the quantitative assessment of myocardial perfusion SPECT (MPS). Two major …

Purpose The segmentation algorithm ESM based on an elastic surface model was validated
for the assessment of left ventricular volumes and ejection fraction from ECG-gated …

A system for quantitative analysis of myocardial perfusion tomograms is proposed. The
system starts with an automated delineation of the total left ventricle, including possible …

Objectives This paper describes a novel approach (same-patient processing, or SPP) aimed
at improving left ventricular segmentation accuracy in patients with multiple SPECT studies …

Background In order to determine myocardial salvage, accurate quantification of
myocardium at risk (MaR) is necessary. We present a validated novel automatic …

Background Efficacy of reperfusion therapy can be assessed as myocardial salvage index
(MSI) by determining the size of myocardium at risk (MaR) and myocardial infarction …

Using global constraints and dynamic programming, a new model-based segmentation
algorithm was developed to determine myocardial borders and basal plane. The segmented …
