This X-ray phase imaging system includes a plurality of gratings including a first grating that is irradiated with X-rays from an X-ray source and a second grating that is irradiated with X-rays from the first grating. The X-ray phase imaging system includes an imaging unit that optically images a subject and one or both of the first grating and the second grating.

Disclosed herein is a mobile fluoroscopic imaging system, and methods of use. A table top imaging system can include a support, an x-ray source carried by the support, an x-ray detector carried by the support and positionable at a distance from the source; a primary x-ray propagation axis extending between the source and the detector. The distance between the source and the detector can be adjustable along the axis, and the axis can be angularly adjustable throughout an angular range.

A method, device, and computer program product for capturing projection images of an object are provided. An x-ray beam source is moved by a control unit on a path into a plurality of positions, in which an x-ray beam is transmitted. An x-ray beam detector is moved by the control unit into a plurality of positions, in which the x-ray beam, penetrating the object, is detected. The x-ray beam source and/or the x-ray beam detector are moved on a calculated path around the object, at a constant distance between the x-ray beam source and the x-ray beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central x-ray beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the x-ray beam detector and the object is minimized.

The present disclosure provides an X-ray machine, which comprises a C-shaped arm. The C-shaped arm includes a connecting arm, a first support arm, and a second support arm. The first support arm and the second support arm are separately movably connected to the connecting arm. The first support arm moves relative to the connecting arm to move close to or away from the second support arm, and the connecting arm moves to drive the first support arm to move close to or away from the second support arm. An adjustable range of a distance between the first support arm and the second support arm is wider, so that when the radiation source is arranged on the second support arm and the detector is arranged on the first support arm, an adjustable range of a distance (SID) between the radiation source and the detector is wider.

Radiographic imaging system including: an x-ray transmission unit; an x-ray receiver unit; a plate made from a material opaque to x-rays and situated between the transmission unit and the receiver unit, the plate including at least four channels, each channel enabling a part of the x-rays emitted by the transmission unit to pass through the channel; and an image processing unit configured to determine the coordinates of the projected patterns and to calculate a position of the receiver unit from the coordinates of the projected patterns and from the coordinates of the channels.

A breast imaging apparatus includes a radiation generation unit configured to generate radiation and a radiation detection unit configured to detect radiation irradiation from the radiation generation unit and can rotate the radiation generation unit and the radiation detection unit in a state in which they face each other. Imaging is performed in a state in which a body part (breast) of an object to be imaged is sandwiched by a pressing panel on a first side of the breast imaging apparatus. In addition, imaging is performed while rotating the radiation generation unit and the radiation detection unit in a state in which the body part (breast) of the object to be imaged is inserted between the radiation generation unit and the radiation detection unit from a second side opposite to the first side of the breast imaging apparatus.

An apparatus for Digital Imaging in the Head Region of a Patient includes an X-ray source and an X-ray sensor, supported on i a rotary arm supported on a structure by a motor driven translation and rotation means. The rotary arm is provided with adjustment means for varying the distance between the source and the sensor. The apparatus comprises a single sensor for both panoramic imaging and computed tomography, and has a control unit, that controls the source, the sensor, the adjustment means, and the translation and rotation means and operates the apparatus in a basic operation mode for bigger patients and in an alternative operation mode for smaller patients, in which the distance between the source and the sensor is reduced as compared to the distance used for the basic operation mode.

A method for fluoroscopy energizes a radiation source to form a scout image on a detector and processes the scout image to determine and report a radiation field position with respect to a predetermined zone of the detector. The radiation source is energized for fluoroscopic imaging of a subject when the reported radiation field position is fully within the predetermined zone.

An extra-oral dental imaging apparatus for obtaining an image from a patient has a radiation source; a first digital imaging sensor that provides, for each of a plurality of image pixels, at least a first digital value according to a count of received photons that exceed at least a first energy threshold; a mount that supports the radiation source and the first digital imaging sensor on opposite sides of the patient's head; a computer in signal communication with the digital imaging sensor for acquiring a first two-dimensional image from the first digital imaging sensor; and a second digital imaging sensor that is alternately switched into place by the mount and that provides image data according to received radiation.

An extra-oral imaging apparatus is intended to obtain a cephalmetric image of a portion of a head of a patient. Exemplary apparatus embodiments of cephalometric functionality of such extra-oral imaging apparatus can include a cephalometric sup port mounted to a base of the imaging system that is configured to position a cephalometric sensor about a cephalometric imaging area so that x-rays impinge the cephalometric sensor after radiating the cephalometric imaging area. A cephalometric patient positioning unit mounted to the cephalometric support can be positioned between an x-ray source of the x-rays and the cephalometric sensor. A cephalometric alignment sight can be mounted to patient positioning unit to provide a visual indication of alignment between the x-ray source and the mounted alignment sight/cephaolmetric sensors. Exemplary methods are provided that can use such exemplary cephalometric alignment sights and/or install cephalometric functionality to imaging systems using the same.
