Space-time segmentation using level set active contours applied to myocardial gated SPECT.

Space-time segmentation using level set active contours applied to myocardial gated SPECT.

This paper presents a new variational method for the segmentation of a moving object against a still background, over a sequence of [two-dimensional or three-dimensional (3-D)] image frames. The method is illustrated in application to myocardial gated single photon emission computed tomography (SPEC...
