Cone beam CT utilizing a rotational digital radiographic system. Early clinical experience on pulmonary and skeletal lesions

Utilizing a rotational digital radiographic system (SF-VA100, Hitachi), 289 digital images were obtained during a 360-degree rotation in 4.8 seconds. The images were transferred to a high-speed workstation and post-processed to create volume data in 9 minutes. The multi-planar reconstruction method reconstructed high-quality tomographic images with equal resolution in any direction. We applied this system as a cone beam CT in order to demonstrate pulmonary and spinal lesions. Early clinical experience suggested the usefulness of the method in the evaluation of diseases in organs with high radiographic contrast. (author)
