Abstract :
The axial sampling requirements in cardiac positron emission tomography (PET) studies for the detection of myocardial defects has been investigated using stationary and beating heart phantoms. This study examines the relationship between defect volume quantification and axial sampling frequency in a stationary myocardium. The effect that myocardial motion has on this relationship is determined. The variation in volume and activity quantification as a function of defect position in the tomograph is discussed
