ACOUSTIC IMAGING SYSTEM AND METHOD OF ACOUSTIC IMAGING WITH CONTRAST QUANITFICATION |
摘要 |
A system (100) and method (400) of acoustic imaging receives an acoustic signal that is scanned to interrogate a target volume within a subject (430), processes the received acoustic signal to produce three-dimensional acoustic image data for a region of interest within the target volume (450); and quantifies the contrast of the three-dimensional acoustic image data in the region of interest at a sampling time that is offset by a selected time period with respect to a time when a contrast enhancement medium is introduced into the subject's circulatory system (480). In one embodiment, quantification is performed by setting an intensity threshold (410), and determining a percentage of voxels of the three-dimensional acoustic image data for the region of interest which have an intensity value greater than the intensity threshold (470).
