Abstract

The invention discloses an ultrasonic peeping probe and an elastic imaging system and method. The ultrasonic peeping probe comprises an ultrasonic transducer array including multiple ultrasonic transducers for transmitting ultrasonic waves and receiving ultrasonic echoes, reflected by the biological tissue to be detected of ultrasonic waves, and a self-focused ultrasonic transducer for producing focused ultrasonic wave beams, wherein the focused ultrasonic wave beams produce an acoustic radiation force acting on the biological tissue to be detected. The ultrasonic peeping probe produces the focused ultrasonic wave beams through the self-focused ultrasonic transducer, acts on the biological tissue to be detected through the acoustic radiation force of the focused ultrasonic wave beams and accordingly makes the biological tissue to be detected deform. Accordingly, the ultrasonic echo signals of the biological tissue before and after compression are obtained by adopting the ultrasonic peeping probe without the external force exerted by an operator, the operating process is simple and convenient without external mechanical devices, and the system cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of ultrasonic elastography, in particular to an ultrasonic endoscopic probe and an elastography system and method. Background technique [0002] Elastography converts the acquired elasticity information of biological tissues into visible light images that doctors are accustomed to, so that doctors can distinguish the material mechanical properties of biological tissues through visible light images, and then judge the possible pathology of the corresponding tissues or organs based on the soft and hard conditions of the biological tissues Change and its position, shape and size. Generally, the material mechanical properties of biological tissues are sensed by touch, and the essence of tactile perception is how difficult it is for the material to deform after being touched. If the material is easily deformed, the information perceived by the sense of touch is that the material is softer; otherwise, it is harder. T...
