  • Patent number: 10295485
    Abstract: An x-ray transmission spectrometer system to be used with a compact x-ray source to measure x-ray absorption with both high spatial and high spectral resolution. The spectrometer system comprises a compact high brightness x-ray source, an optical system with a low pass spectral filter property to focus the x-rays through an object to be examined, and a spectrometer comprising a crystal analyzer (and, in some embodiments, a mosaic crystal) to disperse the transmitted beam, and in some instances an array detector. The high brightness/high flux x-ray source may have a take-off angle between 0 and 15 degrees, and be coupled to an optical system that collects and focuses the high flux x-rays to micron-scale spots, leading to high flux density. The x-ray optical system may also act as a “low-pass” filter, allowing a predetermined bandwidth of x-rays to be observed at one time while excluding the higher harmonics.

  • Patent number: 10172585
    Abstract: An imaging system such as a medical C-arm x-ray fluoroscopy machine includes a tracking system that tracks a position of an x-ray source and an x-ray detector using sensors which monitor positions of joints which allow relative motions of segments in a support for the x-ray source and detector. Sensor readings are used in a kinematic chain. One or more segments that behave in a non-rigid manner are replaced by a virtual rigid link in the kinematic chain that takes into account deformations of the segments (e.g. under the influence of gravity). Calibration methods permit calibration of the system using images of phantoms.

  • Patent number: 10143430
    Abstract: One aspect of the present disclosure relates to a system that can employ multi-modal imaging to provide an image with an enhanced resolution. In some instances, the multi-modal imaging can allow an operator to determine and control a tissue margin without the need for intra-operative tissue pathology. The system can include an imaging system that includes a gamma camera to detect a gamma image and an optical imaging modality to detect an optical image. The system can also include a display device to display an enhanced gamma image created based on a function of the optical image. The enhanced gamma image illustrates a characteristic of a disease in the field of view (e.g., a lymphatic pathway, a sentinel lymph node target, or a satellite disease state).

  • Patent number: 10147511
    Abstract: Linear ribs are formed radially with a center at a through-hole on one face of an X-ray transmissive film (radiolucent film) in an X-ray transmissive window (radiolucent window) to be used for an X-ray detector (radiation detector). The X-ray transmissive window faces a sample. A beam for irradiation to the sample passes through the through-hole, and X-rays (radiation) are radially emitted on a line extending through the through-hole and enter the X-ray transmissive window. Since the linear ribs are formed radially with the center at the through-hole, even X-rays entering at shallow angles with respect to the X-ray transmissive window are transmitted through the X-ray transmissive window at a probability equivalent to X-rays entering at deep angles. More X-rays are transmitted through the X-ray transmissive window, and thus the X-ray detector can detect X-rays with high efficiency.

  • Patent number: 10136864
    Abstract: An X-ray apparatus for image acquisition and a related method. The apparatus comprises a field-of-view corrector (CS) configured to receive a scout image (SI) acquired by the imager with a tentative collimator setting in a pre-shot imaging phase where said imager operates with a low dosage radiation cone causing the detector to register the scout image. The low dosage cone has, in the detector's image plane, a first cross section smaller than the total area of the detector surface. The field-of-view corrector (CS) uses said scout image to establish field-of-view correction information for a subsequent imaging phase where the imager is to operate with a high dosage radiation cone, the high dosage higher than the low dosage.

  • Patent number: 10141081
    Abstract: A phase grating for a phase contrast X-ray imaging device has a transverse surface which is to be aligned substantially transversely with respect to a radiation incidence direction and which is spanned by an x-axis and a y-axis perpendicular thereto. The phase grating is formed from a multiplicity of grating webs composed of a basic material, which are arranged alternately with optically denser interspaces. The grating webs subdivide the transverse surface into grating strips which are in each case elongated in the y-direction and which are lined up parallel alongside one another in the x-direction. The phase grating has in each grating strip along a z-axis, which is perpendicular to the transverse plane, a homogeneous total thickness of the basic material which always differs between adjacent grating strips. At least one grating web extends within the transverse surface over a plurality of grating strips.
