Provided herein are diffractometer-based global in situ diagnostic systems and uses thereof. The systems may comprise one or more tissue diffractometers that are configured for acquiring in situ diffraction data for a subject, e.g., a patient, and that are operatively coupled to a computer database over a network. The one or more tissue diffractometers may be configured for transfer of data such as image data, diffraction pattern data, subject data, or any combination thereof to the computer database over the network. The systems may further comprise one or more computer processors operatively coupled to the tissue diffractometers, which computer processors may be configured to receive the data from the tissue diffractometers, transmit the data to the computer database, and process the data using a data analytics algorithm which may provide a computer-aided diagnostic indicator for the individual subject.

This disclosure relates to planning systems and methods. The planning systems and methods disclosed herein may be utilized for planning orthopaedic procedures to restore functionality to a joint, and may include one or more calibration objects for calibrating images of patient anatomy.

Aspects of the disclosure provide for an x-ray detection device for detecting radiation scattered off of a target during an imaging procedure and generating temporal data indicating the time of occurrence of a pulse of radiation emitted towards the target. The temporal data can be sent to a host device and used to timestamp images generated from the pulses of radiation. The x-ray detection device is portable and can be installed in a catheterization laboratory or imaging environment to detect the occurrence of radiation, without occluding or partially occluding the beam source. Aspects of the disclosure also provide for a system for receiving temporal data generated by the x-ray detection device, and accurately tagging received image frames based on the temporal data.

A radiation imaging system includes a radiation detector configured to capture a radiation image based on emitted radiation, a control apparatus configured to control the radiation detector, a radiation generation apparatus configured to emit the radiation, and a plurality of relay apparatuses configured to connect these apparatuses. In the radiation imaging system, the control apparatus performs maintenance of the relay apparatuses via the radiation detector.

A method and system for determining a PET image of the scan volume based on one or more PET sub-images is provided. The method may include determining a scan volume of a subject supported by a scan table; dividing the scan volume into one or more scan regions; for each scan region of the one or more scan regions, determining whether there is a physiological motion in the scan region; generating, based on a result of the determination, a PET sub-image of the scan region based on first PET data of the scan region acquired in a first mode or based, at least in part, on second PET data of the scan region acquired in a second mode; and generating a PET image of the scan volume based on one or more PET sub-images.

The present disclosure directs to a system and method for controlling a radiation exposure on a subject. The method includes obtaining exposure instructions including an exposure state of an imaging device. The method also includes determining first components associated with the imaging device and one or more target operations of the first components corresponding to the exposure state. The method further includes generating target operation instructions based on the one or more target operations of the first components. The method still further includes controlling the first components to implement the target operation instructions.

A method of imaging a breast compressed with a foam paddle includes emitting an x-ray energy from an x-ray source towards the breast and the foam paddle having a plurality of upper markers and a plurality of lower markers, wherein the plurality of lower markers are movable relative to the upper markers. The x-ray energy is detected at a detector disposed opposite the breast from the x-ray source. An image of the compressed breast is generated based on the detected x-ray energy. At least one of the plurality of upper markers and at least one of the plurality of lower markers is identified in the image. A thickness of the compressed breast at a plurality of thickness locations is determined, wherein each of the plurality of thickness locations corresponds to at least one of the plurality of lower markers.
