  • Patent number: 10260945
    Abstract: An integrated circuit for an imaging system is disclosed. In one aspect, an integrated circuit has an array of optical sensors, an array of optical filters integrated with the sensors and configured to pass a band of wavelengths onto one or more of the sensors, and read out circuitry to read out pixel values from the sensors to represent an image. Different ones of the optical filters are configured to have a different thickness, to pass different bands of wavelengths by means of interference, and to allow detection of a spectrum of wavelengths. The read out circuitry can enable multiple pixels under one optical filter to be read out in parallel. The thicknesses may vary non-monotonically across the array. The read out, or later image processing, may involve selection or interpolation between wavelengths, to carry out spectral sampling or shifting, to compensate for thickness errors.

  • Patent number: 10192295
    Abstract: The current document is directed to digital-image-normalization methods and systems that generate accurate intensity mappings between the intensities in two digital images. The intensity mapping generated from two digital images is used to normalize or adjust the intensities in one image in order to produce a pair of normalized digital images to which various types of change-detection methodologies can be applied in order to extract differential data. In one approach, a mapping model is selected to provide a basis for statistically meaningful intensity normalization. In this implementation, a genetic optimization approach is used to determine and refine model parameters. The implementation produces a hybrid intensity mapping that includes both intensity mappings calculated by application of the mapping model and intensity mappings obtained directly from comparison of the images.

In certain embodiments, a method for calculating and applying single and hybrid second-derivative splitting filters to gray-scale images and binary bone masks is described. These filters can accurately identify the split lines/planes of the bones even for low-resolution data, and hence accurately morphologically disconnect the individual bones. The split bones can then be used as seeds in region growing techniques such as marker-controlled watershed segmentation. With this approach, the bones can be segmented with much higher robustness and accuracy compared to prior art methods.

  • Patent number: 10062165
    Abstract: A borderline extraction element 15 extracts a borderline B of adjacent vertebrae from an X-ray image on which multiple vertebrae are projected connected in a line. A vertebral area setting element 17 sets a area sandwiched by the adjacent borderlines B as a vertebral area and an area number is put to the respective vertebral areas L. When the vertebral areas are erroneously set up, a setup data erase element 21 erases the data of the vertebral areas L and the area number when the borderline is corrected. The setup data are erased, so that the borderline B can be shift-corrected to any location. A vertebral area setting element 17 resets the vertebral area L based on the location of the corrected borderline. Accordingly, the respective vertebral areas L are set up to the accurate locations and only the borderline B extracted to the wrong location is shift-corrected and the vertebral areas are reset. The work-burden to the operator for setting the vertebral area can be largely lessened.

  • Patent number: 10043111
    Abstract: There is provide a medical image processing apparatus, a medical image processing method, and a medical image processing program that can accurately specify at least either vertebral bodies or intervertebral discs included in the vertebra even if parts of the vertebral bodies and the intervertebral discs are deformed. A candidate detection unit detects intervertebral disc candidates and vertebral body candidates from a medical image, and a centerline detection unit detects a spine centerline. A distribution generation unit generates the distribution of a feature amount indicating the intervertebral disc likeness and a feature amount indicating the vertebral body likeness on the spine centerline. A specification unit specifies at least either the intervertebral discs or the vertebral bodies included in the medical image based on the distribution.

  • Patent number: 10028718
    Abstract: Data of a predetermined volume portion of an object under examination is captured by an x-ray system that includes an x-ray source and a detector. The x-ray source is activated to generate x-rays that emerge from the x-ray source, radiate through the volume portion, and after radiating through, impinge on the detector. X-rays impinging on the detector are captured pixel by pixel, in order to capture the data of the predetermined volume portion. With the pixel-by-pixel capture, only a subset of all the pixels of the detector is evaluated.

  • Patent number: 10021324
    Abstract: Provided is a method of correcting a defective pixel of a digital image. In the method, the defective pixels are pre-corrected. The similarities of normal pixels and each defective pixel are calculated. The weight of each normal pixel to each defective pixel is calculated based on the similarities of the normal pixels and each defective pixel. The weight of each normal pixel to each defective pixel is normalized. The normalized weighted values of the normal pixels to each defective pixel are weighted summed to obtain the corrected pixel value of each defective pixel.

  • Patent number: 10015413
    Abstract: A camera system captures an image in a source aspect ratio and applies a transformation to the input image to scale and warp the image to generate an output image having a target aspect ratio different than the source aspect ratio. The output image has the same field of view as the input image, maintains image resolution, and limits distortion to levels that do not substantially affect the viewing experience. In one embodiment, the output image is non-linearly warped relative to the input image such that a distortion in the output image relative to the input image is greater in a corner region of the output image than a center region of the output image.
