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.

A whole-body transmission x-ray scanner includes an x-ray source, an x-ray camera, a controller, and a positioner aligning the source and camera to point x-rays towards the camera and moving the source and camera synchronously to scan and acquire radiographic images of an object located therebetween. The positioner includes a closed-loop cable alignment assembly fixed to the source and to the 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 includes a motor controlled by the controller, a bi-directional crossover slide track bearing assembly connected to the source, and a conveyor connected to the motor and bearing assembly such that, actuation of the motor by the controller moves the slide track bearing assembly in a loop that correspondingly move the source and camera along a single linear axis.

Provided herein is technology relating to radiology and radiotherapy and particularly, but not exclusively, to apparatuses, methods, and systems for multi-axis medical imaging of patients in vertical and horizontal positions.

A mobile radiography apparatus with a portable transport frame has a sectioned vertical column mounted on the transport frame. The sectioned vertical column defines a vertical axis and has a vertically fixed base section and an upper section that is movable with respect to the base section along the vertical axis. Cable and pulley systems are coupled to the vertical column sections and/or the transport frame. A boom is coupled to the movable section for positioning an x-ray source attached to the boom.

A urological device include a patient table with longitudinal and broad sides, and an X-ray imaging system containing an X-ray source and an X-ray detector for detecting the X-ray radiation emitted by the X-ray source towards the patient on the patient table. A first linear drive is provided for moving the X-ray source parallel to the broad side and a second linear drive is provided for moving the X-ray detector parallel to the broad side, but in an opposite direction. A dedicated pivoting mechanism is configured to pivot the X-ray source around a first pivot axis.

A medical radiation device, including a main frame, and a radiation assembly and an imaging assembly respectively located at an end of the main frame. After an imaging scan is completed and diseased tissue positioning images are taken, a patient is directly moved to the other end of the main frame to allow the radiation assembly to perform a radiation treatment to improve the efficiency of the radiation treatment after the completion of diseased tissue positioning, and effectively reduce movement of the patient when the patient is being moved for radiation treatment after the imaging assembly completes diseased tissue positioning, thus reducing a positioning error of the diseased tissue caused by too much movement.

The purpose of the present invention is to prevent the risk when the wire-rope that is hanging an X-ray irradiation element including an X-ray tube breaks. The X-ray imaging apparatus to solve the above problem comprises a wire-ropes 17, 18 that hang and support an X-ray irradiation element 5 and have a different fatigue strength each other, wherein the different between the fatigue progressions of the wire-ropes 17, 18 takes place, the wire-rope 17 or the wire-rope 18 having a weaker fatigue strength breaks first and both wire-ropes 17, 18 never break simultaneously.

Device comprising: a chassis (1) which supports the entire assembly, a telescopic column (2) which comprises a lower fixed portion (5) rotating with respect to a vertical axis, and at least one upper mobile portion (6), a telescopic arm (3) that moves along the vertical column and that supports an x-ray emitter (4) at its end, wherein the telescopic arm-head assembly can be moved from the lower position of the mobile column in its retracted position to the upper position of the mobile column in its extended position, and also in that all the movements of the column are manual and have a mechanical balancing mechanism which comprises a first mechanism consisting of a spring, a block and tackle, and a variable radius pulley all housed in the fixed portion of the column, and a second balancing mechanism consisting of a recovery pulley and a two-radii pulley which balances the weight between the input of the cable and that of the telescopic arm and head assembly.

A radiation CT apparatus includes a rotation unit configured to rotate about a rotation axis, a radiation generation unit and a radiation detector which are fixed on either side of the rotation axis in the rotation unit, and a gantry cover containing the radiation generation unit and the radiation detector and including a breast insert portion configured to insert a breast of an object. An opening portion that can be opened and closed is placed on the gantry cover of the radiation CT apparatus. The radiation generation unit and the radiation detector are stopped to form a space that allows a user to access the breast insert portion from the opening portion.

A nuclear medicine tomography system comprising: a detector carrier having a circular or partially circular aperture and defining a plane; a plurality of SPECT detector assemblies attached to the detector carrier and arranged around the aperture; a patient carrier movable relative to the plane; each detector assembly comprising an arm defining an extension axis and at least one detector head movable along the axis, wherein each detector assembly has a rounded distal portion; wherein each detector head is extendible along the axis, from the detector carrier toward the patient carrier; and a controller to: control, based on desired bore size and shape, extension and retraction of the detector heads to a spatial arrangement defined by the extension and retraction, control data acquisition by the detector heads, and control image reconstruction of acquired data; the controller further configured to control data acquisition and/or image reconstruction, based on the spatial arrangement.
