Segmentation of left ventricle on dynamic MRI sequences for blood flow cancellation in Thermotherapy

作者：

Highlights：

•

• The use of new external energy term dependent on the pdf of MRI signal.

• New energy is embedded in the active contour model (ACM) to segment left ventricle.

• Temporal propagation of the ACM through data to improve the convergence of the AC.

• Results are 50% better than 3 reference methods results in term of Jaccard distance.
