Abstract
The invention concerns an apparatus for treating a biological sample by emitting focused high intensity ultrasounds towards a focal point, characterised in that it comprises means emitting wideband focused ultrasounds. The apparatus enables to adjust the focused ultrasound frequency according to the target attenuation, the thickness of the tissues traversed, the temperature evolution, or the lesion displacement during emission.
