Supporting devices for small and portable X-ray devices are described in this application. In particular, this application describes a supporting device for a portable X-ray device that contains a movable base unit containing multiple legs with different lengths and heights configured so that the legs have a nestable configuration, an adjustable member extending from the mobile base unit where the adjustable member is configured with an adjustable height, an extension arm connected to the adjustable member where the extension arm is configured to collapse toward and extend away from the adjustable arm, and a connecting member configured to connect the extension arm with a portable x-ray device where the connecting member is able to rotate up to 360 degrees in the x, y, or z direction. The connecting member can also be configured to connect the extension arm with a portable x-ray device so that the portable x-ray device being removable from the connecting member and capable of being operated independently by hand. X-ray systems that contain such a supporting device and such a portable x-ray device are light and easy to move from location to location by medical personnel. The x-ray systems are also extremely versatile during medical procedures because the support device provides a wide range of motion for images to be taken of a patient using the portable x-ray device. Other embodiments are described.

A mobile radiography system includes a wheeled transport frame and a telescoping vertical column mounted on the transport frame. The vertical column includes a stationary base section and a vertically movable upper section coupled to the base section. A cap is positioned in a nest at the top of the movable upper section whereby a counterweight in the movable upper section displaces the cap when the counterweight is extended through the nest and replaces the cap in the nest when the counterweight is retracted into the movable upper section. A padded section of the nest and the counterweight prevents impact noise when the cap contacts the nest or the counterweight. Magnets are used to hold the cap and the nest together in alignment when they are adjacent.

A mobile radiography system includes a wheeled transport frame and a vertical column mounted on the transport frame. A telescoping arm is attached to the vertical column and to an x-ray tube head. The telescoping arm includes a first section, a second section movable within the first section, and a third section movable within the second section. The first section and the second section each include a drag assembly configured to provide a drag force on the linearly movable section therewithin. The drag assemblies each include a friction material pressed against the linearly movable section to provide a constant drag force on the linearly movable section while it moves. A permanent pressure source presses the friction material against the linearly movable section.

A telescopic lifting unit with a first segment, a second segment, and a third segment. The first and second segments may be displaced relative to one another, and the second and third segments may be displaced relative to one another. The first and second segments may be moved relative to one another by a motor unit, and the second and third segments may be moved relative to one another by a cable hoist.

A whole-body transmission x-ray scanner includes a collimated x-ray source, a linear x-ray camera configured to detect x-rays, a counterweight, and a positioner that aligns the source and ray camera and moves the source and camera synchronously to scan and acquire radiographic images of an object located therebetween. The positioner comprises a cable alignment assembly connecting the counterweight directly to the x-ray source and camera to maintain alignment of the source and camera during a scanning mode in which the source and camera move from one end of the object to another end. The positioner comprises a motor, a bi-directional crossover slide track bearing assembly connected to the source, and a conveyor operatively connected to the motor and to the slide track bearing assembly to move the slide track bearing assembly in a loop that correspondingly translates the source and camera along a single linear axis.

The present disclosure relates to an X-ray imaging apparatus. The X-ray imaging apparatus includes a first column connected to a main body, a second column connected to the first column and provided to be movable relative to the first column, an arm connected to the second column and slidably provided along the second column, and a weight compensator provided to compensate for the weight of the second column and the arm, wherein the weight compensator, the second column and the arm are connected by a wire, and the second column is provided with an elastic member connected to the arm and providing an elastic force such that the arm is moved by a uniform force regardless of the position of the second column.

The present invention provides a moving type radiation device improved in usability. The stroke of an intermediate member in a conventional configuration can be increased when an effective diameter of a pinion with respect to an effective diameter of a lower sprocket is determined so that a magnitude of a relative movement that occurs when a lower sprocket and the pinion between an X-ray tube and the intermediate member becomes larger than the magnitude of the relative movement between the X-ray tube and the intermediate member. In the device according to the present invention, the intermediate member moves further toward the floor side than in a conventional device. The operator can move the device while feeling high operability in a state in which the visibility is not interrupted by the intermediate member.

A radiation medical device, comprising a main support, and a radiation assembly (30) and an imaging assembly (20) respectively located at both ends of the main support. After an imaging scan is completed and pathological tissue positioning pictures are taken, a patient is directly moved to the other end of the main support to allow the radiation assembly (30) to perform radiation therapy to improve the efficiency of the radiation therapy after the completion of pathological tissue positioning, and effectively reduce movement of the patient when the patient is being moved for radiation therapy after the imaging assembly (20) completes pathological tissue positioning, thus reducing pathological tissue positioning error caused by too much movement.

This X-ray apparatus for rounds includes an X-ray generator capable of moving up and down in a vertical direction, a holding frame that holds a compression spring or a tension spring that expands and contracts as the X-ray generator moves up and down such that the compression spring or the tension spring is expandable and contractable, that holds a wire rope that transmits an elastic force of the compression spring or the tension spring to the X-ray generator and a pulley around which the wire rope is wound and which rotates, and that supports the X-ray generator such that the X-ray generator is movable up and down, and a support column that extends in the vertical direction and houses the holding frame such that the holding frame is detachable and upwardly exposable.

A cone beam computed tomography imaging system uses a C-shaped structure to revolve a source and detector around an imaging axis. To balance the system a counterweight is attached to the C-shaped structure at one end adjacent to the detector. The source is attached to another end of the C-shaped structure opposite the detector.
