An imaging support device used in a radiography apparatus including a radiation source and a radiation image detector that detects a radiation image of a subject on the basis of radiation emitted from the radiation source and transmitted through the subject includes an optical camera that outputs an optical image by optically imaging a region including an irradiation field of the radiation applied to the subject from the radiation source, and at least one processor, in which the processor associates the optical image acquired by the optical camera with the radiation image on the basis of a timing signal transmitted from the radiation image detector side.

A radiation detector includes a sensor panel unit, a support table to which the sensor panel unit is attached, and two fixing members. The sensor panel unit includes two sensor panels. The sensor panel has pixels that sense visible light converted from radiation and generate charge. The sensor panel unit has a configuration in which an end portion of one sensor panel and an end portion of the other sensor panel are arranged to overlap each other in a thickness direction. A first fixing member fixes two sensor panels in an overlap region in which the end portions overlap. A second fixing member fixes the sensor panel unit and the support table in the overlap region. The second fixing member at least partially overlaps the first fixing member in the overlap region in a plan view of the sensor panel unit in the thickness direction.

A radiation detector has a sensor panel unit which includes two sensor panels and in which end portions of the two sensor panels are arranged to overlap each other in a thickness direction. An image processing unit acquires two projection images from the two sensor panels. A combination unit of the image processing unit performs a process related to image quality on the projection image in a case in which a tomographic image which is a diagnosis image to be used for a doctor's diagnosis is generated and does not perform the process related to image quality on the projection image in a case in which a scout image which is a confirmation image for confirming a reflected state of the subject is generated.

An imaging apparatus for use with an imaging device in order to image a subject. The imaging device includes an annular gantry having an opening and a table to accommodate the subject or a portion thereof for imaging. The imaging apparatus includes a platform and a positioning device. The imaging device is mounted to the platform. The annular gantry is in a fixed position relative to the platform. The table is horizontally displaceable relative to the annular gantry. The positioning device supports the platform and is configured to horizontally displace the platform relative to a supporting surface for the subject. The positioning device is configured to position the platform with the imaging device in at least one operational state in such a way that, during a relative movement of the table with respect to the annular gantry, the table remains stationary relative to the supporting surface.

A mini C-arm with a movable X-ray source is disclosed. The mini C-arm including a moveable base, a C-arm assembly, and an arm assembly for coupling the C-arm assembly and the base. The C-arm assembly includes a first end, a second end, and a curved intermediate body portion defining an arc length. The source is positioned adjacent to the first end. A detector is positioned at the second end. The source is moveable along the arc length and relative to the detector to enable a plurality of images of the patient's anatomy to be acquired including a first image when the X-ray source is at a first position and a second image when the X-ray source is at a second position. The images being taken without moving the patient's anatomy. The C-arm assembly may include a motor and a belt drive system for moving the source relative to the detector.

Various embodiments discussed herein utilize a C-shaped imager to provide images with a minimal footprint, such as may be suitable in a surgical context. In addition the systems and methods described herein allow for suitable angular (i.e., azimuthal) scan coverage about the patient. To provide real-time 3D imaging, multiple X-ray tubes or a distributed X-ray source may be employed, coupled with an extended detector or multiple detectors. To reconstruct high-quality volumes, in some implementations reconstruction techniques may be employed that utilize pre-operative (pre-op) computed tomography (CT), magnetic resonance imaging (MRI), ultrasound (U/S), or other suitable modality images or data as prior information.

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 radiography apparatus includes: an irradiation unit that emits radiation; an arm that can hold the irradiation unit and an image receiving unit in a facing posture; a first rotation mechanism that rotates the arm; and a friction mechanism that is switchable between a first state in which a frictional force is applied to the arm in a direction opposite to a direction in which the arm is rotated and a second state in which the frictional force applied to the arm is less than that in the first state.

Various methods and systems are provided for stationary CT imaging. In one embodiment, a method for an imaging system includes activating a plurality of emitters of a stationary distributed x-ray source unit to emit x-ray beams toward an object within an imaging volume, where the x-ray source unit does not rotate around the imaging volume, receiving attenuated x-ray beams with one or more detector arrays to form a sparse view projection dataset, where each attenuated x-ray beam generates a different view, and reconstructing an image from the sparse view projection dataset using a sparse view reconstruction method.

A method includes receiving a selection of an examination template including a hierarchical examination workflow and baseline configuration parameters corresponding to the examination template, wherein the examination template is associated with an anatomical area; automatically configuring an imaging system with the baseline configuration parameters from the examination template; capturing image data of a patient using the imaging system according to the hierarchical examination workflow; storing the image data on a storage system, such that the image data is associated with the anatomical area; displaying an anatomical model of a plurality of anatomical areas of the patient; and displaying thumbnails of the image data on respective areas of the anatomical model corresponding to anatomical areas of the patient where the image data was captured by the imaging system.
