The invention further relates to a microwave-induced thermo-acoustic and color Doppler ultrasound bi-modal breast imaging detection method. The microwave-induced thermo-acoustic imaging and the color Doppler ultrasound imaging are combined to accurately detect the breasts and the device and the method belong to the technical field of the thermo-acoustic imaging and the color Doppler ultrasound imaging.

Description

technical field [0001] The invention relates to the technical fields of thermoacoustic imaging and color ultrasound imaging, in particular to a set of devices for detecting mammary glands, and in particular to a thermoacoustic color ultrasound dual-mode imaging detection device and method. Background technique [0002] Microwave thermoacoustic imaging is a tomographic imaging technology that uses pulsed microwaves to irradiate biological tissues to excite thermoacoustic signals. It not only has good image contrast for different tissues by microwave imaging, but also has the advantage of high resolution of ultrasonic imaging images, which is beneficial to tissue Detailed observation and analysis of structures. Microwave thermoacoustic imaging will become a new type of nondestructive testing technology. [0003] The principle of using microwave thermoacoustic imaging to detect breast cancer is that there is a significant difference in the absorption of electromagnetic waves b...
