Embodiment Construction

[0020] exist figure 1 The tiltable stand is shown in . The base 100 preferably has at least one supporting base 101, 102, which are most preferably fastened, eg by screws or bolts, to a supporting floor, which may be the floor of a hospital room. Preferably, a supporting structure 103 is provided to connect the supporting bases 101, 102 to a solid base. In addition, at least one strut 104, 105 is provided. In this embodiment, the first strut 104 is mounted on the first support base 101 and the second strut 105 is mounted on the second support base 102 . Bearings 110 are mounted on top of the struts 104 , 105 to hold the tiltable frame 200 . The tiltable frame 200 holds a rotating member 300 having an axis 310 of rotation. On each side of the rotating part, the tiltable frame is held by one of the struts 104,105. In order to turn the rotating part, a drive system is provided. It preferably consists of a motor 210 with at least one pulley 211 for driving a belt 212 which a...

Abstract

A CT scanner gantry comprises a base with a tiltable frame holding a rotating part, the rotating part having a rotation axis and drive means for tilting the tiltable frame with respect to the base. Furthermore, a tilt drive control unit is provided to control the drive means. In inclination sensor is provided at the tiltable frame to indicate the inclination of the tiltable frame with respect to the center of gravity of earth to the tilt drive control unit.

Description

technical field [0001] The present invention relates to X-ray CT (Computed Tomography) scanners, and more particularly to devices for monitoring specific characteristic parameters of CT scanners. Background technique [0002] A traditional x-ray CT scanner has a gantry that holds the x-ray tube and detectors. The gantry has fixed parts and it stands or is mounted on the floor of the hospital room. In addition, it has a rotating part held at a fixed part by bearings. The swivel member holds the X-ray tube and the X-ray detector in relative position and enables them to rotate about a patient table on which a patient can be placed. For certain types of imaging, at least the rotating part of the gantry can be tilted relative to the various parts of the stationary part and the patient table. [0003] A common CT scanner is disclosed in US Pat. No. 6,301,324. A tiltable swivel part of a stage is disclosed in US Patent 6,097,030. Here, a detector position sensor such as a deco...
