+image computing platform [@Kikinis:2013]. The software addresses challenges in liver surgery planning by 
 applying geometric modeling and artificial intelligence to generate liver tumor 
 resection plans for complex cases, developing parameterized patient-specific 
 vascular territory segments, and creating computational methods for resection visualization
