A Deep Boltzmann Machine-Driven Level Set Method for Heart Motion Tracking Using Cine MRI Images

In radiation therapy, heart motion characterization can provide useful information for analyzing the risk of radiation-induced cardiotoxicity and establishing motion management strategies for optimized treatment delivery. Magnetic resonance imaging (MRI)-guided radiation therapy systems provide on-board cine images and allow systematic and quantitative investigations of heart motion during radiation treatment (Chen et  al., 2015; Huang et al., 2015; Weygand et al., 2016). Manual delineation of heart contours is time-consuming and therefore not practically feasible for clinical workflows.
