Abstract:
1. A method for monitoring a therapeutic treatment device having an acoustic treatment transducer, an imaging probe and a display device, said method comprising steps of: emitting first acoustic waves from the acoustic transducer toward a target in order to treat the target, emitting second waves from the imaging probe to provide an imaged representation of the target and the target's environment, before, during and after the emission of the first acoustic waves from the transducer, forming images of the target from said second waves, said images including interference images from said first waves, displaying images of the target taken by the probe before and/or after the emission of the first acoustic waves and interference images of the target, taken during the emission of the first acoustic waves on the display device, detecting a change of structure of the interference images, monitoring any effect of the first acoustic waves by observing said change of structure, and detecting any rise in brightness measured between interference images that are successive in time constituting a change of structure of the interference images which is indicative of the effect of the first acoustic waves.
