Finite-element quick image reestablishment system and method for optoacoustic mammary gland imager

Abstract

The invention discloses a finite-element quick image reestablishment system and method for an optoacoustic mammary gland imager. The system comprises a data collection module, a data resampling moduleand a quantitative image reestablishment module. The data collection module is used for conducting data collection on the mammary gland of the human body through the optoacoustic mammary gland imager; the data resampling module is used for conducting quick imaging on data collected by the data collection module, observing whether or not a suspected focus exists in an illumination area according to an imaged graph and intercepting data with the suspected focus to obtain valid data of a laser radiation area; the quantitative image reestablishment module is used for conducting quantitative imaging on output data of the data resampling module through a finite element algorithm and reestablishing hemoglobin concentration and oxygen saturation images of the suspected focus and the periphery ofthe suspected focus. According to the system, when the focus is analyzed, the images are cut through the quick image reestablishment system, the illumination area with the diameter of 5 cm is cut, sothat the grid diameter becomes extremely small when the finite-element algorithm is conducted, the imaging precision is guaranteed, and the imaging speed is also guaranteed.

Description

Technical field [0001] The invention relates to the technical field of breast imaging, in particular to a finite element fast image reconstruction system and method used in a photoacoustic breast imager. Background technique [0002] At present, the methods used for breast disease examination are mainly various imaging methods, such as: mammography X-ray imaging, magnetic resonance imaging, ultrasound imaging, and infrared imaging. However, these traditional imaging techniques have certain limitations. Infrared imaging technology is the most used, but the resolution of infrared imaging technology is low, the shape of the diseased tissue is blurred, and it is difficult to determine the specific shape and location, resulting in high clinical misdiagnosis and missed diagnosis rates. [0003] For the analysis of lesions, the parameters of hemoglobin concentration and oxygen saturation are mainly obtained through photoacoustic imaging data. Since the lateral diameter of the human breas...
