Embodiment Construction
[0028] The technical solutions in the embodiments of the application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the application. Obviously, the described embodiments are only for illustration and are not intended to limit the application.
[0029] In order to realize the reconstruction of the image of the sound velocity distribution inside the tissue, the present invention provides a method of ultrasonic CT sound velocity imaging based on prior reflection imaging. First, a plurality of piezoelectric ultrasonic transducers are surrounded in a circular array to surround the target body (in this example, breast), and put them into the water tank (which contains water); secondly, make each ultrasonic transducer (as a transmitter) send pulsed sound wave signals in turn, and at the same time, other ultrasonic transducers (as a receiver) receive The original data is obtained from the signal; finally, the received ...
