摘要：
The invention relates to a device and method for generating tomograms. By means of the combination of the device and method, results equivalent to those obtained with traditional CAT systems can be obtained, using very few projections obtained in a limited angular range of movement of a source-detector assembly and/or elevated mechanical tolerance in the positioning of the source and detector. The device comprises: an X-ray imaging device with an assembly comprising an X-ray source (1) and an X-ray detector (2), with movement； a surface scanning device (4)； and a data control and processing system configured to execute at least one calibration routine and one specific tomogram generation routine that uses data obtained by the X-ray imaging device and the surface scanning device to refine the geometric calibration according to the current trajectory and obtain a clinical-quality tomographic image (suitable for clinical diagnosis).
