Abstract :
Quantitative analysis of dynamic cardiac PET studies provides useful diagnostic information regarding different heart diseases. To correctly perform the kinetic analysis, tracer time-activity curves (TAC) must be precisely extracted from the chosen tissue on the imaging data. In this work we present an alternative clustering algorithm for segmentation of dynamic studies using a leader-follower clustering approach, in which the number of clusters is unknown.
