Thermoacoustic, photoacoustic and ultrasonic three-mode breast tumor detection device and method

Abstract

The invention relates to a thermoacoustic, photoacoustic and ultrasonic three-mode breast tumor detection device and a thermoacoustic, photoacoustic and ultrasonic three-mode breast tumor detection method. The thermoacoustic, photoacoustic and ultrasonic three-mode breast tumor detection device comprises a pulse train generator, a microwave source, a laser source, an ultrasonic emitting source, acoupler, a detector, a data acquisition module and an image processing module, wherein a tissue to be detected is placed inside the coupler; energy of the microwave source, the laser source and the ultrasonic emitting source is radiated into the coupler; generated thermoacoustic, photoacoustic and ultrasonic signals are jointly received by the detector; then, the signals are acquired by the data acquisition module and transmitted into the image processing module; the image processing module reconstructs thermoacoustic, photoacoustic and ultrasonic images by a back-projection algorithm to obtain three-mode images; finally, the three-mode images are superposed and synthesized on the same image. The thermoacoustic, photoacoustic and ultrasonic three-mode breast tumor detection device integrates the advantages of respective single modes in one system, and can not only eliminate misdiagnosis of breast edema, inflammation and fibroadenoma, but also improve the accuracy of early breast cancerdetection through combination of multiple parameter indexes.

Description

technical field [0001] The invention belongs to the technical field of thermoacoustic, photoacoustic and ultrasonic imaging, and in particular relates to a thermoacoustic, photoacoustic and ultrasonic three-mode breast tumor detection device and method. Background technique [0002] At present, medical imaging generally uses a single modality for imaging. Existing single-modal medical imaging has its limitations, such as thermoacoustic imaging, which can only provide information at the deep lesion tissue and molecular levels; photoacoustic imaging, which can only effectively image the structure and function of biological tissues The structural morphology, physiological and pathological characteristics, function and metabolism research of human body provide important methods and means; ultrasound imaging can only be used for imaging at the level of histomorphology, but ultrasound is hindered by gas and bone, and the tissue contrast is low. Specifically: [0003] Thermoacous...
