Abstract

A micro-CT (computed tomography) system with spatial resolution down to 6 urn was developed at SPring-8 using an X-ray indirect-conversion type detector incorporating a fluorescent screen and a lOM-pixel CCD camera for 3-D biomedical imaging. The detector's X-ray field of view was 24 mm wide by 16 mm high. X-rays are converted into a visible image in a phosphor layer of the screen, and a visible light image is detected by the CCD camera. Following the barium sulphate angiography, a rabbit auricle specimen implanted with VX2 carcinoma was fixed in formalin. 2D images were recorded for different angular positions of the specimen. A 3D image of the specimen was obtained by tomographic reconstruction, and 3D microangiographic features of small tumor blood vessels were demonstrated.
