Abstract
The invention relates to a device for the heat treatment of a target region of a biological tissue, comprising: energy generator means for delivering energy to a focal point (P) in the target region; means for measuring the spatial temperature distribution in said region; a control unit comprising means for controlling the displacement of the focal point (P) towards successive treatment points and means for controlling the energy to be delivered by the generator means to the successive treatment points, characterized in that the control unit further includes means for determining a spatial and energy distribution of the treatment points where treatment is to be carried out, each successive treatment point having a position and a treatment energy that are determined according to the positions and spatial and energy distributions of the previous treatment points. The invention also relates to the associated heat treatment method.
