Abstract:
1. A method for ultrasound imaging of anatomical tissue using an ultrasound transducer, comprising the steps of: a) positioning the ultrasound transducer relative to the anatomical tissue; b) receiving a time-varying first signal of a first imaging ultrasound wave which has been reflected from a location in the anatomical tissue during a first time period, the first imaging ultrasound wave being generated by the ultrasound transducer; c) receiving a time-varying second signal of a second imaging ultrasound wave which has been reflected from the location in the anatomical tissue at a later second time period following a discrete ultrasound medical treatment, the second imaging ultrasound wave being generated by the ultrasound transducer; d) subtracting the second signal from the first signal to derive a time-varying difference signal; and e) generating an indication from the difference signal, the indication showing the effect of the discrete ultrasound medical treatment in the location in the anatomical tissue.
