ADVANCES IN NON-SURGICAL MANAGEMENT OF LIVER TUMOR

Abstract

The robotic-assisted liver tumor therapy by targeted delivery of drugs into the tumor is an innovative technique applied in the case of nonresectable tumors. It is difficult for the surgeon to perform by himself the surgical plan because of some major difficulties which may occur during the procedure, such as the insertion trajectory of the needle can touch the ribs, blood vessels and other tissues and organs in the vicinity of the liver, or the inserted needle may cause deformation of liver which can change the map of the tumor surroundings. Thus, an effective surgical plan is needed. To overcome these difficulties the optimization of the needle free-collision trajectories is performed by using the particle swarm optimization algorithm. The paper was presented to the International Multi-Conference on Systems & Structures (SysStruc '19), Reșița, November 7-9, 2019.
