摘要： A region of interest (ROI) of a patient's body is repeatedly scanned using an ultrasound transducer array. Data sets representing an image property, such as intensity, from portions of the ROI are used to calculate a representation of the displacement profile within the ROI at different stress levels. From the displacement profile, a function of strain is also preferably calculated. According to one aspect of the invention, a data set representing an estimate of the elasticity profile within the ROI is color-coded and is displayed along with a B-mode display in a single, overlaid display. According to another aspect of the preferred embodiment of the invention, the display of elasticity is adaptively persisted as a function of, for example, a measure of image quality. The invention also provides an on-screen guide that indicates to a user a measure of quality of each of a series of estimated displacement data sets.
