According to one embodiment, an X-ray computed tomography apparatus includes an X-ray tube, a photon counting detector, and processing circuitry. The X-ray tube radiates X-rays. The photon counting detector detects the X-rays radiated from the X-ray tube and transmitted through a subject. The processing circuitry adjusts a temperature adjustment amount used for regulating a temperature of the photon counting detector according to an imaging mode.

Methods, systems, and apparatus for performing spectral tomographic reconstruction of an object. The imaging system includes a power source that is configured to provide a variable high voltage. The imaging system includes a distributed X-ray source. The distributed X-ray source includes an array of X-ray emitters that allows fast switching “ON” and “OFF” using X-ray emitter grid electrode. The distributed X-ray sources is configured to generate an X-ray beam with an energy spectrum based on the variable high voltage and uses additional X-ray filters. The imaging system includes a controller. The controller is configured to operate synchronously with the change of the variable high voltage. The controller is configured to control a timing of when to engage an X-ray emitter of the array of X-ray emitters of the distributed X-ray source based on a predefined firing pattern.

A panoramic X-ray imaging apparatus includes: an X-ray generating unit; an X-ray detecting unit; a support that supports the X-ray generating unit and the X-ray detecting unit; a drive mechanism that turns at least the X-ray generating unit and the X-ray detecting unit by driving the support; a displacement mechanism that adds movement including a displacement component in a direction different from the turning to the X-ray detecting unit; a subject holding unit that holds an imaging subject; a turning controller that controls the turning by a drive mechanism and the displacement mechanism. The turning controller controls the drive mechanism and the displacement mechanism so as to add the movement avoiding the contact with the shoulder of the imaging subject during the turning of the X-ray generating unit and the X-ray detecting unit by the drive mechanism during the panoramic X-ray imaging.

A C-arm X-ray apparatus includes an x-ray emitter (5) and an X-ray detector (4) which are maintained on a C-arm (2) mounted on a reference plane. The x-ray emitter (5) has nanorods as electron emitters and has an elongated structure which is at least partially aligned along a surface normal of the reference plane.

A computed tomography device comprises: a gantry with an opening and a radiation protection apparatus configured to cover the opening, wherein the opening is configured to receive an examination object introduced into the opening along a system axis of the gantry; wherein the radiation protection apparatus has a radiation protection curtain, a curtain mounting and a pivot apparatus; wherein the curtain mounting has a bar-shaped area; wherein an upper edge of the radiation protection curtain is attached to the bar-shaped area such that the radiation protection curtain is stretched along the bar-shaped area and hangs down from the bar-shaped area; and wherein the curtain mounting is pivotably supported relative to the gantry about a pivot axis via the pivot apparatus.

A pressure regulator for an x-ray apparatus includes a piston housing having a recess formed therein and a piston seated in the recess. The piston is free to reciprocate, and define a variable volume chamber, within the recess. A circumferential groove is formed in an exterior surface of the piston, and a seal is seated in the circumferential groove. A manifold in the piston housing places the chamber in fluid communication with an exterior of the piston housing.

Embodiments generally relate to routing a bundle of loose cables with a cable chain during a medical procedure. The cable chain comprises split tubing and a plurality of links extending discretely along a length of the split tubing. Each link comprises a housing including an outer surface and an inner surface. The outer surface comprises a magnet and the inner surface forms a recess in the link. The split tubing is disposed within the recesses of the links.

The computed tomography device has a gantry with an opening and a radiation protection apparatus for covering the opening. The radiation protection apparatus includes a radiation protection cover and a pivoting apparatus, wherein an object under examination may be inserted into the opening along a system axis of the gantry when the radiation protection cover is in a first position relative to the gantry. The radiation protection cover is pivotably mounted relative to the gantry about a pivot axis by the pivoting apparatus such that a first pivoting motion of the radiation protection cover about the pivot axis enables the radiation protection cover to be lowered relative to the gantry from the first position to a second position. The computed tomography device may furthermore include at least one of a lighting system or a camera system.

A mobile computed tomography system has a gantry with an opening for at least partially accommodating a patient, and a carriage configured to be moved over a substrate with motor assistance. The gantry is arranged on an upper side of a support frame of the carriage. The support frame includes at least one shaped profile tube.

The invention relates to a computer-assisted tomography (CT) system having the following features: a) at least one X-ray source, b) at least one patient couch for supporting a patient, c) at least one first X-ray detector, provided permanently or at least temporarily in the ray path of the X-rays radiated by the X-ray source through the patient couch, d) at least one second X-ray detector, provided permanently or at least temporarily in the ray path of the X-rays radiated by the X-ray source through the patient couch, e) at least one actuable drive mechanism, using which the first and/or second X-ray detector can be moved from a position in the ray path of the X-rays radiated by the X-ray source through the patient couch, to a position outside the ray path and vice versa, f) at least one electronic control device that is configured to actuate the drive mechanism.
