  • Patent number: 10828000
    Abstract: A system for analyzing image data can include a processor to detect a set of medical images and partition each medical image into a plurality of non-overlapping or overlapping patches. The processor can also generate an ordered set of patch clusters derived from the medical images, wherein the patch clusters are sorted based on a type of tissue identified in each of the medical images. Additionally, the processor can generate a digital representation of a percentage of the type of tissue calculated for each of the medical images and transmit an alert in response to detecting that the percentage of the type of tissue for an image exceeds a predetermined threshold.

  • Patent number: 10398398
    Abstract: A method and an apparatus for estimating a geometric thickness of a breast in mammography/tomosynthesis or in other x-ray procedures, by imaging markers that are in the path of x-rays passing through the imaged object. The markings can be selected to be visible or to be invisible when the composite markings/breast image is viewed in clinical settings. If desired, the contribution of the markers to the image can be removed through further processing. The resulting information can be used determining the geometric thickness of the body being x-rayed and thus setting imaging parameters that are thickness-related, and for other purposes. The method and apparatus also have application in other types of x-ray imaging.

  • Patent number: 10393681
    Abstract: The present invention relates to an X-ray Talbot interferometer including a source grating including a plurality of X-ray transmitting portions, configured to allow some of X-rays from an X-ray source to pass therethrough; a beam splitter grating having a periodic structure, configured to diffract X-rays from the X-ray transmitting portions by using the periodic structure to form an interference pattern; and an X-ray detector configured to detect X-rays from the beam splitter grating. The beam splitter grating diffracts an X-ray from each of the plurality of X-ray transmitting portions to form interference patterns each corresponding to one of the plurality of X-ray transmitting portions. The plurality of X-ray transmitting portions are arranged so that the interference patterns, each corresponding to one of the plurality of X-ray transmitting portions, are superimposed on one another to enhance a specific spatial frequency component in a sideband generated by modulation of the interference patterns.

  • Patent number: 10386788
    Abstract: An infrared imaging system includes a phase grating overlying a two-dimensional array of thermally sensitive pixels. The phase grating comprises a two-dimensional array of identical subgratings that define a system of Cartesian coordinates. The subgrating and pixel arrays are sized and oriented such that the pixels are evenly distributed with respect to the row and column intersections of the subgratings. The location of each pixel thus maps to a unique location beneath a virtual archetypical subgrating.

  • Patent number: 10365235
    Abstract: Provided is a radiation phase-contrast imaging device capable of assuredly detecting a self-image and precisely imaging the internal structure of an object. According to the configuration of the present invention, the longitudinal direction of a detection surface of a flat panel detector is inclined with respect to the extending direction of an absorber in a phase grating. This causes variations in the position (phase) of a projected stripe pattern of a self-image at different positions on the detection surface. This is therefore expected to produce the same effects as those obtainable when a plurality of self-images are obtained by performing imaging a plurality of times in such a manner that the position of the projected self-images on the detection surface varies. This alone, however, results in a single self-image phase for a specific region of the object.
