摘要： A subject support apparatus (100) includes a plurality of chambers (102) configured to hold a fluid under pressure and support a living being. At least one pressure transducer (108) determines a pressure of at least one of the chambers (108) and generates a signal indicative thereof. A controller (124) dynamically controls fluid entering and leaving the at least one chamber (102) based on the signal, thereby maintaining a pre-determined pressure range in the at least one chamber (102).

摘要： A roller truck for supporting a rotating drum of a CT scanner, including a spring plate having opposing ends, top and bottom surfaces and unconstrained side edges. At least two axles are secured to the spring plate, and an attachment member is secured to the spring plate between the two axles. The attachment member is for securing the roller truck to one of a support frame of the CT scanner and the drum mounted for rotation on the frame. Rollers are rotatably mounted on each axle of the truck for supporting and allowing the instrument drum to rotate. The spring plate is free to resiliently bend about the attachment member and is adapted such that, when the instrument drum is rotated, resulting vibration frequencies are shifted by the roller truck to minimize distortions in images produced by the CT scanner.

摘要： In an improved computed tomography scanner drive system and bearing configuration, a gantry disk is sheaved about its perimeter such that the gantry is operable as a driven pulley rotatable about an object to be scanned. A motor assembly mounted to a stationary frame includes a similar sheaved drive pulley. A belt tensioned between the drive pulley of the motor assembly and the driven pulley of the gantry disk transfers rotational motion of the motor to drive the gantry rotationally about the object. In a preferred embodiment, the belt comprises a V-belt or poly-V-belt, and the bearing comprises a wire bearing located proximal to the gantry center of mass. In this manner, the present invention provides a simple and effective technique for driving the gantry about the object, providing sufficiently accurate angular positioning in a reliable and cost effective drive system.
