Method of imaging scatterers based on acoustically stimulated changes of their acoustic properties

摘要

A method of imaging blood with the use of contrast agents. A sequence or ensemble of imaging pulses is transmitted into a patient. Echo signals received in response to each of the imaging pulses are received and analyzed to determine if the echoes are produced by tissue or by the contrast agent. Echoes produced by the contrast agent are detected by an echo signal that changes in amplitude or a centroid frequency that changes with each imaging pulse. Once the location of the contrast agent has been determined, an image is created whereby the contrast agent is highlighted for view by a physician or sonographer.
