Abstract
A tomographic scanner for subjecting a planar region of a patient to radiation and producing an image representing the planar region in which at least the source or beam of radiation is moved with a varying speed. In particular, in a traverse and rotate type scanner, a carriage carrying the radiation source and detector(s) is traversed relative to the patient with generally simple harmonic motion. Additionally, vibration is reduced by using a motor, which may include a flywheel, running at substantially constant speed to traverse the carriage. Vibration is further reduced by connecting the motor for rotating the carriage to the carriage through a flexible, e.g. chain, drive. Cable connections to the X-ray tube and other elements carried by the moveable carriage are simplified with a bicycle-chain like flexible cable support.
