Abstract: A computed tomography X-ray scanner, in which a monochromatic X-ray beam is generated by irradiating an X-ray producing target with high energy monoenergetic ions. The ion beam is preferably produced by a cyclotron. The X-ray beam is preferably rotated through an object to be scanned by angularly displacing the ion beam and target about the center axis of the object. A conventional X-ray detector array, a signal and data processor and imaging means are provided to convert detected X-ray absorption measurements into a two-dimensional visual image of the scanned object cross-section.
