A mobile x-ray device includes a telescopic column including a fixed portion and an telescopic portion vertically moveable relative to the fixed portion, a telescopic arm moveably connected to the upper telescopic portion of the telescopic column, a head assembly for obtaining x-ray images on the telescoping arm, a wire rope connected to the telescopic portion and the telescoping arm for providing the vertical movement of the telescopic portion and telescoping arm, and a counterbalancing mechanism for balancing the weight of the telescopic portion and the telescopic arm during movement thereof. The counterbalancing mechanism includes a block and tackle connected to the wire rope and a compression spring connected to and extending between the fixed portion and the block and tackle for storing potential gravitational energy of the telescopic portion and telescoping arm during either synchronous or non-synchronous movement of the upper telescopic portion and telescoping arm.

A method includes receiving a subject support motion disable signal indicative of at least one of power removal of an imaging system, a collision of a horizontally moving tabletop of the imaging system, a decoupling of a horizontal motion drive system configured to horizontally drive the tabletop, or a collision of a vertically moving subject support of the imaging system, wherein a vertical motion drive system drives the subject support vertical motion, and disabling, in response to receiving the subject support motion disable signal, at least one of tabletop horizontal motion or subject support vertical motion.

A mobile x-ray apparatus having wheels for manual transport and an x-ray tube support attached to a base. The apparatus may be rolled by pushing and/or pulling the base, the support, or the x-ray tube. A brake is associated with at least one of the wheels to prevent rolling the apparatus when manually positioning the x-ray tube. The brake may be engaged from an actuator on the tube head, on the support, or on the base.

A vehicle includes a computed tomographic system (CT) including a CT gantry having an inner peripheral, and a subject window in a surface of the vehicle. The subject window is configured to be exposed to an exterior of the vehicle via a side face of the vehicle, such that the subject window is configured to enable a subject to enter or exit from the inner peripheral of the CT gantry in a body axis direction of the CT.

Disclosed herein is an ultrasonic imaging apparatus of displaying functions related to the ultrasonic imaging apparatus on a display unit when the ultrasonic imaging apparatus moves, and activating a function selected by a user from among the functions displayed on the display unit. According to an embodiment, the ultrasonic imaging apparatus includes: a display unit configured to display one or more functions related to movement of the ultrasonic imaging apparatus when the ultrasonic imaging apparatus moves; and a controller configured to activate a function selected by a user from among the one or more functions displayed on the display unit.

An imaging method, accesses a set of low-energy projection images and performs a low-energy reconstruction using the low-energy projection images. A synthesized intermediate low-energy projection image is generated. A high-energy reconstruction is performed using a set of high-energy projection images. A synthesized intermediate high-energy projection image is generated. A dual-energy reconstruction is performed using at least one low-energy projection image, the synthesized intermediate low-energy projection image, at least one high-energy projection image, and the synthesized intermediate high-energy projection image.

Provided is a mobile radiation generation apparatus which reliably prevents the unsteady motion of a carriage unit with a simple structure and facilitates the fine adjustment of the position of a radiation emitting unit. Each of a front wheel and a rear wheel of a carriage unit is a caster that swivels about a swivel axis extending in a vertical direction. A support that vertically stands on the carriage unit supports a base end of an arm unit having a free end to which an X-ray emitting unit is attached. The arm unit rotates about a rotation axis parallel to the swivel axis with respect to the carriage unit. The carriage unit includes a front pedal that is provided closer to the front wheel than the support and is used to lock both the rotation and swivel of the caster at the same time.

Provided is a mobile radiation generation apparatus which reliably prevents the unsteady motion of a carriage unit with a simple structure and facilitates the positioning of an operation panel even in a case in which a wheel of the carriage unit is a caster. Each of a front wheel and a rear wheel of a carriage unit is a caster that swivels about a swivel axis extending in a vertical direction. An operation panel is provided in a main body unit mounted on the carriage unit. The operation panel rotates about an axis that extends in the Z-axis direction with respect to the carriage unit. The carriage unit includes a front pedal that is provided closer to the front wheel than a support and locks both the rotation and swivel of the caster at the same time.

An x-ray imaging system, such as a mobile radiography unit, includes a plurality of stationary carbon nanotube based x-ray sources to be selectively energized. A circuit enables a selected subset of the radiation sources to be energized while another subset may be disabled. A light source may be attached to the support arm of the mobile radiography unit and a source of electric power is configured to energize the light source upon operator contact with the unit. The plurality of stationary x-ray sources may be used to capture a plurality of 2-D projection images of a subject to reconstruct a 3-D image thereof. The 3-D image is used to generate a 2-D projection image of the subject.

An N-M tomography system comprising: a carrier for the subject of an examination procedure; a plurality of detector heads; a carrier for the detector heads; and a detector positioning arrangement operable to position the detector heads during performance of a scan without interference or collision between adjacent detector heads to establish a variable bore size and configuration for the examination. Additionally, collimated detectors providing variable spatial resolution for SPECT imaging and which can also be used for PET imaging, whereby one set of detectors can be selectably used for either modality, or for both simultaneously.
