COUNTERBALANCING MECHANISM FOR X-RAY TUBEHEADS

... - i An X-ray tubehead counterbalancing mechanism devoid of springs, cams and chains is disclosed. The mechanism requires only a single adjustment to precisely counterbalance objects, such as tubeheads and the like. The mechanism includes a commercially available gas spring which is used in conjunction with parallel motion linkage assembly which carries the tubehead. The piston rod end of the gas spring is adjustable upwardly or downwardly in a direction substantially normal to the axis of the piston rod by means of a single adjustment screw cooperation with a clevis which pivotally mounts the piston rod. With such adjustment capability, the present mechanism will support and counterbalance tubeheads having wide variations in weight and inertia.

METHODS AND SYSTEMS FOR CT BALANCE MEASUREMENT AND ADJUSTMENT

The present application discloses a method for detecting an abnormity in an optical path or measuring and adjusting of a dynamic balance of a gantry in a CT system, comprising performing, by a gantry controlled by a controller, a test scan along an optical path of the CT system, the optical path being a path along which rays pass from a ray source to a detector. The method further comprises obtaining, by a processor, data relating to the test scan, and based on the data relating to the test scan. The method further comprises determining, by the processor, a status characteristic index of the optical path or an amount of dynamic imbalance of the gantry. The method further comprises analyzing, by the processor, a result of the status characteristic index; determining, by the processor, whether the optical path is abnormal, or determining whether a dynamic balance of the gantry satisfies a requirement based on a result of the analysis of the amount of dynamic imbalance.

This support comprises two arms which are pivotable about parallel axes and which are coupled to one another in such a way that opposite pivotal movements through equal angles are obtained. The C-shape or the U-shape of the support is then changed, so that the support can be rotated without the risk of a collision with the table top carrying the patient.

Self-adjusting X=ray device - has active device part and position member activated by coupled counter balance

The x-ray device has an active unit (1, 31) and a coupled counterbalance (4,33) via a power transmitting tube (8, 26) and with a position member (15, 39) for adjusting the length of the tube (8, 26). The position member (15, 39) is activated by the counterbalance (4, 33) moving above a lower threshold position resulting in a variation in the length of the tube (8, 26) by an amount which increases with the path of the counterbalance (4, 38) put back by the operation of the position member (15, 39) and is smaller than that path. USE/ADVANTAGE - Reduced expense of manually correcting length of tube after device has been set up.

X-ray apparatus and x-ray detector

An X-ray apparatus includes an X-ray radiator configured to radiate X-rays to an object and a controller configured to acquire orientation information indicating an orientation of the X-ray radiator and motion information indicating a movement of an X-ray detector configured to detect the X-rays radiated by the X-ray radiator and select the X-ray detector based on the orientation information and the motion information.

APPARATUS AND METHOD FOR PROVIDING PATIENT IMAGING

A method of providing imaging of a patient supported by a patient support platform arranged to be rotated about a first patient rotation axis by a patient rotation angle, the method constituted of: rotating an imager about an imager rotation axis by the patient rotation angle; translating the imager along a first imager translation axis; and translating the imager along a second imager translation axis different than the first imager translation axis, wherein responsive to the translation of the imager along the first imager translation axis and along the second imager translation axis, the imager is translated along an imaging axis defined by the patient support platform such that the imager is arranged to image the patient supported by the patient support platform. 1. An imaging apparatus for a patient supported by a patient support platform , the patient support platform arranged to be rotated about a first patient rotation axis by a patient rotation angle , the apparatus comprising:an imager;an imager positioner in communication with said imager and arranged to rotate said imager about an imager rotation axis;a first imager translation mechanism in communication with said imager and arranged to translate said imager along a first imager translation axis;a second imager translation mechanism in communication with said imager and arranged to translate said imager along a second imager translation axis different than said first imager translation axis; and control said imager positioner to rotate said imager about said imager rotation axis by the patient rotation angle;', 'control said first imager translation mechanism to translate said imager along said first imager translation axis; and', 'control said second imager translation mechanism to translate said imager along said second imager translation axis,', 'wherein responsive to said translation of said imager along said first imager translation axis and along said second imager translation axis, said imager is ...
