摘要: An ultrasound system and method for calculation display of strain velocity in real time is disclosed. Strain may be determined from tissue velocity. Tissue by measuring the pulse-to-pulse Doppler shift at range positions along an beam calculating based on shift. The then calculated as a gradient Alternatively, linear regression methods used to calculate directly difference between positions. result determination displayed number manners such M-mode, color-coded video images or time-variation curves, combination, mixture, with B-mode image. A reliability index modify information.
