Oblique irradiation angle CT system

摘要

An oblique-view cone-beam CT system comprises an X-ray source 8 that irradiates an object 4 to be imaged placed on a rotary specimen table 3. The X-ray source irradiates the object with X-ray 12 from an oblique angle to the rotational axis of the object. An X-ray detector 9 detects projection images resulting form the slanted X-ray irradiation and a computer 10 electrically connected to the detector records the detected images and reconstructs these images to provide a three-dimensional (3-D) image. The X-ray source and X-ray detector are mounted on a swingable and vertically adjustable tilting frame 7. A method of obtaining images of a sample using an oblique-view cone-beam CT system is also disclosed.
