Abstract (en)
[origin: WO03017843A1] A way of delivering ultrasound signals includes providing an image of at least a portion of a subject (30) intended to receive ultrasound signals between sources of the ultrasound signals and a desired region of the subject (3) for receiving focused ultrasound signals, identifying, from the image, physical characteristics of portions of material between the sources and the desired region, and using a spectral propagation analysis to determine at least one of phase corrections and amplitude corrections for the sources depending on the respective physical characteristics of the portions of the material disposed between each source and the desired region.
