Abstract
The construction of the imaging system includes: (1) replacing the linear detector of the CT scanner with an image intensifier coupled to a TV camera, (2) modifying the gantry to mount the image intensifier, (3) replacing the system computer by a PC, (4) designing and constructing the interfacing and data acquisition system and (5) developing software for system control and data acquisition. The system consists of a x-ray tube and an image intensifier that are separately mounted on a gantry. The tube-detector set can be rotated over 360 degree(s) in the gantry. Two sets of images acquired with this imaging system indicate that two types of distortion occur in image intensifiers, S distortion and pincushion distortion. In the future, these two types of distortions need to be corrected prior to three-dimensional (3-D) reconstruction.
