Abstract

The invention belongs to the technical field of ultrasonic tomography in biomedical hyper-acoustics, and in particular to an ultrasonic CT sound velocity imaging method based on a deep residual network. The ultrasonic CT sound velocity imaging method based on the deep residual network comprises the following steps that S1, immersing a target detection object into a water tank provided with an annular ultrasonic transducer, S2, extracting signal first arrival points in two sets of original ultrasonic data respectively, corresponding subtraction is conducted, and a transit time difference graphis obtained; S3, constructing a deep residual error network model; s4, making training data and labels and inputting the training data and the labels into the network; training a model, according to the method, the projection data acquired by the acquisition equipment is reconstructed by utilizing the deep residual network in deep learning, so that the precision of a reconstruction result is improved, and the tedious steps of multiple iterations, regularization parameter adjustment and the like are avoided.

Description

technical field [0001] The invention relates to the technical field of ultrasonic tomographic imaging in biomedical ultrasonics, in particular to an ultrasonic CT sound velocity imaging method based on a deep residual network. Background technique [0002] Breast cancer has become the cancer with the highest incidence among women in the world, and its incidence is still showing an upward trend, so effective screening and diagnosis are very important. Ultrasonic CT sound velocity imaging technology has shown great advantages in the early diagnosis of breast cancer due to its advantages of non-radiation, low cost, and the ability to generate quantitative three-dimensional images. This technology uses a ring-shaped ultrasonic transducer array as a measuring device, and detects the structure of the target object by transmitting and receiving ultrasonic waves between the transducers, and uses the information contained in the ultrasonic signals received by the transducers. Ultras...
