Heat distribution improvement with the implementation of polyethylene-covered water bolus into breast cancer hyperthermia
This paper presents the implementation of polyethylene-covered water bolus into a non-invasive breast cancer hyperthermia applicator. This modified hyperthermia applicator is introduced to improve the performance of hyperthermia by reducing or removing unwanted hotspots during hyperthermia treatment...

This paper presents the implementation of polyethylene-covered water bolus into a non-invasive breast cancer hyperthermia applicator.
