Cone-beam X-ray luminescence tomography system of combination imaging and method thereof

Abstract

The invention discloses a cone-beam X-ray luminescence tomography system of combination imaging and a method thereof. The system comprises a charge-coupled device (CCD) camera, an X-ray source, an X-ray detector, an electronic control rotating table and a narrow-band filter, wherein the CCD camera, the X-ray source, the X-ray detector, the electronic control rotating table and the narrow-band filter are coupled with a lens. The CCD camera and the narrow-band filter are fixed in the same direction, and then a to-be-imaged object, the CCD camera and the narrow-band filter are located on the same straight line; the X-ray source and the X-ray detector are placed in the direction perpendicular to the CCD camera, and then the X-ray source, the to-be-imaged object and the X-ray detector are located on the same straight line; and the CCD camera, the electronic control rotating table, the X-ray source and the X-ray detector are controlled to operate by using a computer. According to the cone-beam X-ray luminescence tomography system of the combination imaging and the method thereof, use ratios of X-rays are improved, and medicine of the to-be-imaged object can be fully excited; X-ray irradiation time is shortened, X-ray irradiation doses are reduced, and popularization and application of X-ray excitation imaging are benefited; information fusion of two types of imaging modals is achieved, and more biological characteristics of the to-be-imaged object are acquired.

Description

technical field [0001] The invention belongs to the field of electronic technology, and particularly relates to a combined imaging cone beam X-ray emission tomography imaging system. The invention utilizes cone beam X-rays to excite the medicines in the object to be imaged, not only can the medicines of the object to be imaged be fully excited, but also the three-dimensional anatomical structure information of the object to be imaged can be obtained by using X-ray imaging, so as to obtain accurate information about the anatomical structure of the object to be imaged. The three-dimensional spatial distribution imaging of drugs realizes multimodal imaging in the process of fluorescence tomography of the object to be imaged. Background technique [0002] X-ray computed tomography (CT) technology is widely used to obtain images of anatomical structures with high spatial resolution, but its role in the field of molecular imaging is very limited. Small amounts of several contrast...
