| Research Abstract |
To investigate problems for developing a 3D CT system using a pinhole CCD sensor, 1) a simulation p program, 2) a reconstruction program, 3) a control system for four stepping motor and 4) a CCD control system were developed. By using the simulation program (1), numerical 2D projection data were obtained. The reconstruction images for the data were calculated by using the reconstruction program (2). These results made it possible to evaluate the propriety of the simulation program and the reconstruction program. The control system for four stepping motor (3) made it possible to control up to 4-axis moving. By developing the CCD control system, we could obtain direct projection images. Using all these developed programs and systems, tomographic images, the center of which was above the images obtained by a CCD sensor, could be obtained without problems. However, there is a problem to be left. The insufficient of the x-ray photons made it difficult to obtain the projection using a pinhole CCD sensor. We have to improve this problem in the future.
