摘要
This invention provides a method for determining the position range of the heart from a sequence of projection images which are acquired for 3-D volume reconstruction, such as SPECT myocardial projection data. The essence of this invention is the use of 1-D pseudo motion analysis so that the detection is insensitive to the image intensity distribution. Heart position is determined by comparing the sampled heart motion against a standard heart motion and determining similarities between the two as an indication of the position range of the sampled heart including the proximate center, upper and lower limits of motion.
