Panel PET and optical dual-mode fusion imaging system and method based on breast cancer detection

Abstract

The invention discloses a panel PET and optical dual-mode fusion imaging system and method based on breast cancer detection. The system comprises a signal acquisition subsystem and a computer subsystem, wherein the signal acquisition subsystem comprises a panel PET imaging device and an optical imaging device, and is used for obtaining PET data and optical data; the computer subsystem comprises asystem control module, a data processing module, a data reconstruction module and a data registration module; the data processing module can preprocess the PET data and optical data; the data reconstruction module can reconstruct the preprocessed PET data and optical data respectively to obtain reconstructed images; the data registration module is used for performing registration and fusion on thetwo reconstructed images, so as to realize accurate positioning of breast cancer. The system can perform PET imaging and optical imaging at the same time on a breast, and provides a powerful image technology support for the early accurate diagnosis and prognosis therapeutic evaluation of breast cancer.

Description

Technical field [0001] The invention belongs to the technical field of medical imaging equipment, and in particular relates to a flat-plate PET and optical dual-mode fusion imaging system and method based on breast cancer detection. Background technique [0002] Early and accurate diagnosis of breast cancer is the key to the treatment of breast cancer. Traditional mammography systems include mammography, ultrasound imaging of the breast, and magnetic resonance imaging (MRI). The sensitivity of mammography is strongly dependent on the density of the breast. Breast ultrasound imaging has problems in detecting very small tumors, and cannot distinguish benign and malignant tumors, and it is very dependent on the experience and skills of the operating physician. MRI imaging has a long imaging time, is too sensitive, and is not suitable for patients with metal objects in the body. [0003] With the rapid development of molecular imaging technology in recent years, positron emission tom...

Problems solved by technology

Since photon propagation in biological tissue is affected by scattering, its spatial resolution is relatively low, and the reconstruction problem itself has a certain morbidity. Therefore, the strategy of introducing prior information of other modalities to improve the quality of optical imaging has been studied by many Adopted by the team, but there is currently no breast detection device for PET / optical fusion
