A Fully Automatic Approach for Multimodal PET and MR Image Segmentation in Gamma Knife Treatment Planning

Leksell Gamma Knife ® (Elekta, Stockholm, Sweden) is a stereotactic radiosurgical device to treat different brain disorders that are often inaccessible for conventional surgery, such as benign or malignant tumors, arteriovenous malformations and trigeminal neuralgia [1,2]. Stereotactic radiosurgery allows an accurate external irradiation (with a single, high dose and steep dose gradient) to minimize doses given to adjacent critical brain structures. The gamma rays (generated by Cobalt-60 [60Co] radioactive sources) are focused on the target through a metal helmet.
