A system according to at least one embodiment of the present disclosure includes an imaging source; an imaging detector; a sensor coupled to at least one of the imaging source and imaging detector; and a controller that adjusts a relative position of the imaging source and the imaging detector based on an output of the sensor.

An x-ray diagnosis apparatus according to an embodiment includes an x-ray tube holder, a supporter, an ultraviolet ray, a contact portion detector, and an irradiation controller. The x-ray tube holder holds an x-ray tube. The supporter movably supports the x-ray tube holder. The ultraviolet ray emitter is disposed to the x-ray tube holder and emits ultraviolet rays. The contact portion detector detects a contact portion touched by a subject of detection, which is at least one of a subject of examination and an examination technician. The irradiation controller controls the support to move the x-ray tube holder to a position corresponding to the contact portion, and controls the ultraviolet ray emitter to emit the ultraviolet rays toward the contact portion.

Disclosed is a medical imaging system, including a processor circuit configured for communication with an x-ray imaging device movable relative to a patient and an intravascular catheter or guidewire sized and shaped for positioning within a blood vessel of the patient, wherein the processor circuit is configured to receive a first angiographic image of a first length of the vessel and a second angiographic image of a second length of the vessel, wherein the first image is obtained at a first position and the second angiographic image is obtained at a second position. The processor is further configured to generate a roadmap image of a combined length of the blood vessel by combining the first image and the second image, and to receive intravascular data associated with the blood vessel, and to co-register the intravascular data to corresponding locations in the roadmap image; and output the roadmap image and a graphical representation of the intravascular data at the corresponding locations in the roadmap image.

An imaging capsule including, a radiation source, a collimator that provides a collimated beam from the radiation source, at least one detector configured to detect particles resulting from X-ray fluorescence and/or Compton backscattering in response to the collimated beam to reconstruct images of a user's gastrointestinal tract, wherein the imaging capsule is configured to identify an inflamed area, within the user's gastrointestinal tract, based on a count of the detected particles and initiate actions responsive to detecting the inflamed area.

Medical imaging devices, systems, and methods thereof. The medical imaging system may include a movable station and a gantry. The movable station includes a gantry mount rotatably attached to the gantry. The gantry includes an outer C-arm slidably mounted to and operable to slide relative to the gantry mount, an inner C-arm slidably coupled to the outer C-arm and, an imaging signal transmitter and sensor attached to the C-arms. The two C-arms work together to provide a full 360 degree rotation of the imaging signal transmitter. In embodiment, the imaging signal transmitter and imaging sensor are offset from a center axis of the medical imaging system such that the portable medical imaging system is operable to capture an enlarged field of view.

Various methods and systems are provided for an x-ray imaging system. In one example, a method for decelerating a rotor of an x-ray tube of an imaging system includes controlling and/or monitoring a speed and position of the rotor, passing the rotor through a first position where a force exerted on the rotor, is less than Earth's gravitational pull, the force due to a combination of gravity and radial acceleration, and initiating a predefined deceleration profile to decelerate the rotor to a halt when the x-ray tube passes through the first position.

Method for assessing a position of a patient with respect to an automatic exposure control chamber, AEC chamber (11, 12), for a medical exam, wherein a patient is positioned between an X-ray source and the AEC chamber (11, 12); comprising the steps:—acquiring (S10) an X-ray image (32) of at least part of the patient, wherein the AEC chamber is configured for detecting a radiation dose of the X-ray source;—determining (S20), by the control unit, a position of the AEC chamber (11, 12) with respect to the patient from the acquired X-ray image (32);—determining (S30), by the control unit, an exam protocol performed on the patient dependent on the medical exam to be performed on the patient and determining, by the control unit, an ideal position of the AEC chamber (11, 12) with respect to the patient dependent on the exam protocol, wherein the ideal position relates to a position of the patient relative to the AEC chamber (11, 12), in which the detected radiation dose is reliable for the medical exam; and—determining (S40), by the control unit, a position deviation of the position of the AEC chamber from the ideal position of the AEC chambers; characterized in that determining, by the control unit, the position deviation comprises the steps:—segmenting at least an anatomical structure (21, 22) of the patient in the X-ray image (32) thereby determining at least one segmented anatomical structure (21, 22); and—determining the position deviation dependent on the at least one segmented anatomical structure (21, 22);—determining an overlap of the at least one segmented anatomical structure (21, 22) with the AEC chamber (11, 12); and—determining the position deviation dependent on the determined overlap.

A method is for providing collision information. In an embodiment, the method includes acquiring first position data relating to an outer contour of an object, via at least one measuring device arranged on a gantry of a medical imaging device; receiving second position data relating to an inner contour of an opening of the gantry and/or an outer contour of the gantry; receiving movement data relating to relative movement between the gantry and the object; calculating the collision information relating to a collision of the object and the gantry, based on the first position data, the second position data and the movement data; and providing the collision information.

The invention is directed to a system (100) for image processing, which is capable of improving an usability of an imaging device during an intervention.

The method comprises receiving an image sequence of the subject from the camera during the medical imaging scan; receiving at least one of the current position or velocity of the patient table during the medical imaging scan; performing a motion tracking analysis of the image sequence to extract a motion model, wherein at least one of the motion tracking analysis or the motion model is tailored to the body region of interest and takes into account the at least one of the current patient table position or velocity; and analysing the motion model to detect subject motion and, if the detected motion is above a threshold, at least one of adapting the medical imaging examination or issuing an alert.
