A microwave thermoacoustic breast imaging detection device and method based on a flexible detector

Abstract

The invention relates to a microwave-induced thermoacoustic breast imaging detection device based on a flexible detector. The microwave-induced thermoacoustic breast imaging detection device comprises a detector, wherein the detector is a flexible detector and comprises a sheet-shaped flexible substrate and a plurality of array elements; the sheet-shaped flexible substrate is capable of achieving bending deformation and is incapable of achieving tensile deformation; the sheet-shaped flexible substrate fits with the breast surface shape; the array elements are uniformly distributed on the flexible substrate and are used for receiving ultrasonic signals reflected by the breast. The invention also relates to a microwave-induced thermoacoustic breast imaging detection method based on the flexible detector. The microwave-induced thermoacoustic breast imaging detection device is simple in structure, small in size, light in weight, low in production cost, low in energy consumption, high in resolution ratio, high in contrast ratio and comfortable in detection process, is safe and efficient, is capable of carrying out preliminary detection on the breast cancer, and has a significant effect of facilitating clinical application of the thermoacoustic technology.

Description

technical field [0001] The invention relates to the field of thermoacoustic imaging, in particular to a device for detecting mammary glands, in particular to a microwave thermoacoustic mammary gland imaging detection device and method based on a flexible detector. Background technique [0002] Microwave thermoacoustic imaging is a new type of non-destructive testing imaging technology, which has been increasingly used because of its advantages of high contrast and high resolution, high imaging depth, safety and non-destructive. The principle is that when a substance is irradiated with pulsed microwaves, the substance absorbs microwave energy to cause an instantaneous temperature rise. If the pulse width of the microwave is relatively narrow, the absorbed energy cannot be thermally diffused within the duration of the microwave pulse. At this time, it can be seen For adiabatic expansion, thermal energy is converted into mechanical energy and radiated in the form of ultrasonic ...

AI Technical Summary

Problems solved by technology

When performing breast detection, the hard detector is moved on the surface of the breast by human hands, so this kind of detector has the following disadvantages: 1. Manual operation is required, and the efficiency is low; 2. The parts that are prone to missed detection; .Need to use coupling liquid

In the prior art, there is only the technology of using flexible detectors for the sealing detection of metal boxes, there is no technology of using flexible detectors for microwave thermoacoustic imaging, and there is no technology of using flexible detectors for breast detection
