The invention discloses a finite element rapid image reconstruction system and method for a photoacoustic breast imager. The system includes: a data acquisition module: used for collecting human breast data through a photoacoustic breast imager; a data resampling module: It is used to perform rapid imaging according to the data collected by the data acquisition module, and observe whether there are suspected lesions in the illumination area according to the imaging map, and intercept the data of suspected lesions to obtain effective data in the laser irradiation area; the quantitative image reconstruction module: use Quantitative imaging is performed on the output data of the data resampling module through the finite element algorithm, and the hemoglobin concentration and oxygen saturation images of the suspected lesion and its surroundings are reconstructed. When the present invention analyzes the lesion, the fast image reconstruction system is used to cut the image into an illuminated area with a diameter of 5 cm, so that when the finite element algorithm is performed, the grid diameter becomes very small, which not only ensures the accuracy of imaging , also ensures the speed of imaging.
Description
Technical field [0001] The present invention relates to the field of breast imaging, and more particularly to a finite element fast image reconstruction system and method for a photonic breast imaging device. Background technique [0002] Currently, methods for breast disease test are mainly various imaging methods, such as molybdenum target X-ray imaging, nuclear magnetic resonance imaging, ultrasound imaging, infrared imaging. However, these conventional imaging techniques have certain limitations. Using the most infrared imaging techniques, the resolution of infrared imaging is low, and the shape of the lesion is blurred, it is difficult to determine the specific shape and position, resulting in higher clinical misdiagnosis and mispensal rate. [0003] For the analysis of the lesion, the parameters of hemoglobin concentration and oxygen saturation are mainly passed through the photonic imaging data. Since the lateral diameter of the human body breast is greater than 10 cm duri...
