Abstract

Various methods have been proposed aimed at automatically finding the left ventricular (LV) boundary of the heart from several types of medical imaging modalities. One of the primary reasons why accurate boundaries are sought is for quantitative evaluation of the motion of the heart's walls. Few of these methods work consistently well on nuclear medicine images because of the inherently low signal-to-noise (SNR) ratio and low resolution of the data. This paper discusses a new algorithm which is a more knowledge-based approach to the LV boundary finding and wall motion determination tasks. Information obtained spatially and temporally from a gated sequence of nuclear medicine images is integrated in order to better isolate the LV boundary. Furthermore, information from several views of the heart (and possibly from other modalities) will be used to help with wall motion characterization.
