Abstract
ECG-Gated SPECT is used widely to image myocardial perfusion and wall thickening which are important measures of heart function. An accurate model of the periodic count density variations is needed to estimate both the magnitude and precision of perfusion and wall thickening. We propose a new model of wall thickening which better suits the non-uniform (eccentric) changes in count density than the standard sinusoidal (SIN) model. The sinusoidal eccentric thickening (SET) model is P + W sin( t + 0 ) e(-5 (1-sm( t + 0 )) where P is perfusion, W is wall thickening, t is gate number [1-8], 0 is phase and 8 is the eccentric coefficient in the exponential term.
