Various methods and systems are provided for x-ray imaging. In one embodiment, a method comprises acquiring, with an x-ray detector tilted at an angle with respect to an x-ray source, an x-ray image, calculating the angle from the x-ray image, generating a corrected x-ray image based on the calculated angle, and displaying the corrected x-ray image. In this way, tilt artifacts caused by the x-ray detector being tilted with respect to the x-ray source may be removed from an x-ray image.

An adjustable support for a gantry for a radiotherapy apparatus, wherein the support comprises a base and a mounting member for supporting a gantry, wherein the position of the mounting member relative to the base is adjustable.

At least one power supply produces a voltage between a cathode and an anode. The cathode and anode are operable such that electrons emitted from the cathode interact with the anode with energies corresponding to the voltage. The electrons interact with the anode at a focal spot to generate X-rays. The power supply provides the cathode with a cathode current. An electron detector is positioned relative to the anode, and a backscatter electron signal is measured from the anode. The measured backscatter electron signal is provided to a processing unit, which determines a cathode current correction and/or a correction to the voltage between the cathode and the anode using the measured backscatter electron signal and a correlation between anode surface roughness and backscatter electron emission.

Various embodiments are described herein for a system and method of integrated X-ray imaging and microscopic imaging of an imaging area having a sample on a sample stage. An X-ray apparatus may be disposed within the imaging area and be configured to acquire X-ray image data of at least a portion of the sample. A microscopic imaging apparatus may be disposed within the imaging area and be configured to acquire microscopic image data of the at least a portion of the sample. In some embodiments, a processing unit may then control the X-ray apparatus to acquire X-ray image data of the at least the portion of the sample, and generate one or more corresponding X-ray images; determine a region of interest (ROI) of the sample based on the one or more X-ray images; and control the microscopic imaging apparatus to obtain at least one microscopic image based on the ROI.

A method is disclosed for recording medical images of the human body or that of an animal. The method includes scanning for acquiring data and signaling the start and/or end of a manual administration of a contrast medium in temporal relation to the scan for acquiring data.

An X-ray imaging apparatus and control method for the same relate to a mobile X-ray imaging apparatus that allows a user to recognize whether the X-ray imaging apparatus is in an appropriate imaging distance from an object. The X-ray imaging apparatus includes an X-ray source, an input unit that receives distance information between the X-ray source and an X-ray detector, a reference light emitter that irradiates a light from the X-ray source in a direction where the X-ray detector is placed, at least one auxiliary light emitter that irradiates a light that overlaps with a light from the reference light emitter; and a controller that determines an auxiliary light emitter corresponding to the distance information among the at least one auxiliary light emitter, and controls the reference light emitter and the determined auxiliary light emitter so that the reference light emitter and the determined auxiliary light emitter irradiate a light.

Methods, systems, and devices for medical imaging are described. Examples may include an augmented reality (AR) server receiving a set of medical imaging data acquired by at least a first imaging modality. The set of medical imaging data may include a visual representation of a biological structure of a body. Next, the medical imaging data can be used to render an isolated anatomical model of a least a portion of the biological structure. The isolated anatomical model can be received by an AR viewing device such as AR glasses. The AR viewing device may display on a display of the AR viewing device, a first view perspective of the isolated anatomical model in a first orientation. The first orientation may be based on a position of the first AR viewing device relative to the body. Examples include displaying a virtual position of the medical instrument in the AR viewing device.

An assembly for a system includes a rotatable drum defining a bore and configured for rotation about an object positioned within the bore, a support structure configured to support the rotatable drum during a rotation of the drum, a first radial air bearing disposed between the rotatable drum and the support structure and positioned proximate to a first distal end of the rotatable drum, and a second radial air bearing disposed between the rotatable drum and the support structure and positioned proximate to a second, opposite distal end of the rotatable drum. The first radial air bearing and the second radial air bearing are located at different longitudinal positions along a longitudinal axis of the rotatable drum and the first radial air bearing and the second radial air bearing are configured to levitate the rotatable drum relative to the support structure.

An X-ray filter can include a curved structure for positioning around a computed tomography (CT) bore of a CT scanner. The curved structure can be formed of a metal capable of blocking X-rays emitted by an X-ray source of the CT scanner. The curved structure can include two or more apertures. Each aperture of the two or more apertures can allow X-rays emitted by the X-ray source to enter the CT bore when the X-ray source is aligned with the aperture. The X-ray filter can include an opening, arranged opposite to the two or more apertures across the CT bore, for exposing an X-ray detector of the CT scanner to X-rays emitted by the X-ray source and entering the CT bore through at least one of the two or more apertures. The CT scanner can include the X-ray filter.

Various methods and systems are provided for laser alignment systems, particularly laser alignment systems of medical imaging systems. In one example, a medical imaging system comprises: a gantry; and a laser mount including: a first section fixedly coupled to the gantry; a second section seated within the first section and slideable within the first section; and a third section seated within the second section and rotatable within the second section, the third section adapted to house a laser radiation source.
