More Information
Summary:The invention discloses a CT and X-ray luminescence computed dual-mode synchronous tomography method. Small animal X-ray luminescence computed tomography and computed tomography (CT) can be achieved synchronously, and a more accurate imaging object anatomical structure and molecular imaging information are provided. It is guaranteed that an XLCT projection and a CT projection are collected at the same location and same time by reducing the CT projection angle number and setting the CT projection angle number to be the same as that of the XLCT or be in a diploid relation with that of the XLCT; meanwhile, by means of a compressive sensing principle, a few-angle reconstruction algorithm achieving image total variation minimization is adopted for the CT projection, and a precondition matrix and wavelet transformation are introduced into XLCT iteration reconstruction so as to reduce ill conditioning of reconstruction. According to the CT and X-ray luminescence computed dual-mode synchronous tomography method, sync
