Volumetric ablation is a method to raise the entire tumor volume above a lethal temperature threshold.

	The currently used method to ablate a tumor is by a point by point approach. The target volume is destroyed sequentially in several shots. Each individual shot consist of a «move focal spot - shoot - wait for cooling» sequence and produce a cigar shaped lesion. The complete targeted volume is destroyed by overlapping small individual lesions.
	On the contrary, during volumetric ablation, the focal spot is continuously displaced while heating in such a way the the entire tumor volume temperature is raised above the lethal threshold.
