The Fast Location Methods of Scatters in the Virtual Phased Array Ultrasonic Scattering CT Imaging

A time-space compression method was proposed, which made ultrasonic array signals(wave train) received by virtual phased array transform to two-dimensional grayscale of time-location, and then project to time axis. By studying the characteristics of one-dimensional projection, the existence of scattering interface was quickly identified, and the coarse position of scattering interfaces on the timeline could also be identified.
