Microwave-induced thermoacoustic breast imaging detection device and method based on flexible detector and method thereof

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.
