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.

A radiography apparatus includes an upright imaging stand that is used for radiography on a subject, a camera as a detection sensor that immediately detects a state of the subject with respect to the upright imaging stand, a tablet terminal, and a reflective member. The tablet terminal displays a notification screen including an image output from the camera. The reflective member reflects the notification screen such that the subject facing the upright imaging stand visually recognizes the image.

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.

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.
