Abstract
Disclosed is a synthetic aperture focusing method for ultrasound imaging system based on planar waves. The planar waves are transmitted to a target object with an angle of wave propagation corresponding to a center position of a receive subaperture, and echo signals reflected from the target object are received by the receive subaperture, and the received echo signals are stored in a receive pattern memory, and the stored echo signals are dynamic-focused, and finally the dynamic-focused signals are combined to form at least one beam pattern.
Claims8
A synthetic aperture focusing method for an ultrasound imaging system comprising the steps of:
- producing planar waves by a plurality of transducers;
- transmitting the planar waves to a target object;
- receiving signals reflected from the target object through a plurality of receive subapertures, wherein each receive subaperture is comprised of at least one of the plurality of transducers;
- dynamic-focusing the received signals;
- and
- combining the dynamic-focused signals to form at least one beam pattern.
