Abstract

The invention discloses a tri-modal breast imaging system and an imaging method thereof.A testing system of the tri-modal breast imaging system comprises a frame, first, second and third lifting platforms, a pressing plate, a transparent plate, an X-ray source, an X-ray detector, an ultrasonic array, a laser, a data collection card, a computer, a refractive divergence component and a motion platform or a transfer platform. By means of integration among three modals including photoacoustic tomography, X-ray breast imaging and ultrasonic imaging, one piece of imaging equipment is adopted for tri-modal breast imaging without changing positions of tissue to be tested. The three modals differ in imaging contrast sources and complement with one another in terms of information. Therefore, non-invasive imaging among the structure, physiological and pathological features and the metabolic function of mammary tissue is carried out after images are filtered, projected and fused so that position and size of a tumor can be accurately determined. The tri-modal breast imaging system is particularly suitable for early detection and continuous monitoring of treatment effect of a breast cancer.

Description

technical field [0001] The invention relates to breast imaging technology, in particular to a three-mode breast imaging system including photoacoustic tomography, ultrasonic imaging and X-ray breast imaging and an imaging method thereof. Background technique [0002] According to the statistics of the World Health Organization, 1.2 million women in the world suffer from breast cancer every year, and 500,000 women die of breast cancer. The incidence rate is increasing at a rate of 2% to 8% every year. Approximately 100 million women are currently screened for breast cancer each year. Ultrasound imaging (Ultrasound) and X-ray mammography (Mammography) have been widely used in early breast cancer screening. Although ultrasonography has the advantages of non-destructive, non-invasive, portable, and good distinction between solid tumors and cystic lesions, the sensitivity and specificity of ultrasonography are insufficient, and it is not sensitive to imaging of tiny calcificatio...
