A method and system for detecting an image of an object in an analyzer-based system with a polychromatic x-ray beam from an x-ray source, wherein an analyzer crystal and a detector simultaneously acquire a rocking curve of the x-ray beam for all energies of the x-ray beam. The x-ray beam is diffracted through the object using an asymmetrical monochromator. A detector movement is synchronized with one of the x-ray source or the object. The synchronization includes moving the detector at a first rate that is different than a second rate of the object or the x-ray source, wherein a ratio between the first rate and the second rate is determined by the magnification of the system.

An X-ray imaging system (XI) configured for phase contrast and/or dark-field imaging The system comprises an X-ray source (XS) operable to cause X-radiation to emanate from a focal spot (SF) of the source (XS) and an X-ray sensitive detector (D) operable to SMF detect the X-radiation after interaction of said X-radiation with an object to be imaged, if present, between the X-ray source and the detector (D). A control logic (CL) is operable to cause the X-ray imaging apparatus to operate in any one of two modes, an object image acquisition mode and a scattering measurement mode. When in scattering measurement mode, the X-radiation receivable at the detector comprises a higher proportion of scattering radiation than in X-radiation receivable when the system is in object image acquisition mode.

A Compton camera for medical imaging is divided into segments with each segment including part of the scatter detector, part of the catcher detector, and part of the electronics. The different segments may be positioned together to form the Compton camera arcing around part of the patient space. By using segments, any number of segments may be used to fit with a multi-modality imaging system.

This invention relates to an image processing device (1) comprising an input (2) for receiving image data representative of a region of interest in the body of a patient from a medical X-ray imaging apparatus (100). The image data comprises a first dark-field image obtained for a first X-ray spectrum and a second dark-field image obtained for a second, different, X-ray spectrum. A combination unit (3) provides a combination image that is representative of a medical condition map, e.g. a lung condition map, by combining the first dark-field image and the second dark-field image.

A non-spectral computed tomography scanner (102) includes a radiation source (112) configured to emit x-ray radiation, a detector array (114) configured to detect x-ray radiation and generate non-spectral data, and a memory (134) configured to store a spectral image module (130) that includes computer executable instructions including a neural network trained to produce spectral volumetric image data. The neural network is trained with training spectral volumetric image data and training non-spectral data. The non-spectral computed tomography scanner further includes a processor (126) configured to process the non-spectral data with the trained neural network to produce spectral volumetric image data.

According to one embodiment, an X-ray diagnostic apparatus includes an X-ray irradiator, a scatterer, a grid, and a detector. The X-ray irradiator irradiates X-rays. The scatterer is provided between the X-ray irradiator and an object, that scatters the irradiated X-rays. The grid is provided between the scatterer and the object, that transmits the scattered X-rays within a predetermined angular range. The detector detects X-rays transmitted through the object together with an incident angle of the X-rays.

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.

X-ray backscatter imaging (XBI) methods and systems are provided that enable depth-sensitive information to be obtained from images acquired during a single scan from a single side of an object being imaged. The depth-sensitive information is used in combination with other image information acquired during the scan to produce high-resolution 2-D or 3-D images, where at least one of the dimensions of the 2-D or 3-D image corresponds to depth in the object.

An imaging capsule, including a radiation source, a collimator that provides a collimated beam from the radiation source, a detector configured to detect particles resulting from X-ray fluorescence and/or Compton backscattering in response to the collimated beam, a motor to rotate the collimator and detector around an axle to scan a partial or full inner circumference of a user's colon with radiation, wherein the motor comprises a segmented commutator that is fed with a power signal via brush contacts; and wherein the motor provides a pulsed output signal based on mechanical switching of the segmented commutator on the brush contacts, providing an indication of the rotation angle of the motor as a function of time.

A radiation diagnostic device according to an aspect of the present invention includes a first detector, a second detector, and processing circuitry. The first detector detects Cherenkov light that is generated when radiation passes. The second detector is disposed to be opposed to the first detector on a side distant from a generation source of the radiation, and detects energy information of the radiation. The processing circuitry specifies Compton scattering events detected by the second detector, and determines an event corresponding to an incident channel among the specified Compton scattering events based on a detection result obtained by the first detector.
