A recently granted patent (Publication Number: US11879972B2) discloses a method for detecting elasticity using shear waves in ultrasound imaging. The method involves transmitting ultrasound waves through transducers in an ultrasound probe to focus on at least two points in an acoustic field, creating a shear wave zone that propagates perpendicular to the transmission direction. Detection ultrasound waves are continuously transmitted to the shear wave path, and elastic characteristics are calculated based on the received echo signals. The transducers can be divided into groups to focus ultrasound waves on specific points, with each group having a transmission delay based on the distance to the focus point to ensure simultaneous arrival of waves.

Furthermore, the patent also covers an ultrasound imaging method and an ultrasound elasticity detecting apparatus. The imaging method involves determining focus points in a tissue, dividing transducers into groups corresponding to these points, transmitting ultrasound waves, receiving echo signals, and generating an ultrasound image. The apparatus includes an ultrasound probe with transducers focusing on multiple points, a transmitting/receiving controller for generating transmission parameters, and a data processor for calculating elastic characteristics. The transducers in the apparatus can be divided into groups based on the ultrasound wave parameters, with each group having a transmission delay to ensure synchronized arrival of waves at the focus points, facilitating accurate elasticity detection in ultrasound imaging.
