Ultrasound feedback in medically-treated patients

摘要

A method for ultrasound imaging of patient tissue. A first signal is obtained of a first imaging ultrasound wave which has been reflected back from a location in the patient tissue at a first time. A second signal is obtained of a second imaging ultrasound wave which has been reflected back from the location in the patient tissue at a later second time wherein the patient has received at least some medical treatment by the second time. An image of the location is created using the first signal and the second signal. In one example, the method is repeated for different locations to image the patient tissue, wherein the image of the patient tissue includes medically-treated locations and medically-untreated locations.
