  • Patent number: 10325176
    Abstract: A method of assessing the quality of an retinal image (such as a fundus image) includes selecting at least one region of interest within a retinal image corresponding to a particular structure of the eye (e.g. the optic disc or the macula), and a quality score is calculated in respect of the, or each, region-of-interest. Each region of interest is typically one associated with pathology, as the optic disc and the macula are. Optionally, a quality score may be calculated also in respect of the eye as a whole (i.e. over the entire image, if the entire image corresponds to the retina).

  • Patent number: 10307057
    Abstract: An eye imaging apparatus includes a lighting device including a fundus illuminator and a cornea illuminator; a half mirror; an imaging device including a camera having a first objective lens; and a first polarizer. The first polarizer is disposed between the half mirror and the camera. The fundus illuminator irradiates the half mirror with first light polarized in a direction orthogonal to a transmission axis of the first polarizer. The half mirror receives the first light and outputs resulting light to an eye. A travel direction of the resulting light is in alignment with an optical axis of the first objective lens. The cornea illuminator emits light at a timing different from an emission timing of the first light, and the eye is irradiated with second light based on the light emitted by the cornea illuminator from a direction different from a direction parallel with the optical axis.

  • Patent number: 10013740
    Abstract: The present invention is directed to a novel tomographic reconstruction framework that explicitly models the covariance of the measurements in the forward model using a mean measurement model and a noise model. This more accurate model can result in improved image quality, increased spatial resolution, and enhanced detectability—in particular, for imaging scenarios where there are features on the order of the correlation length in the projection data. Applications where these methods might have particular benefit include high resolution CBCT applications as in CBCT mammography (where very fine calcifications are difficult to resolve due to detector blur and correlation), musculoskeletal imaging (where fine bone details are important to the imaging task), or in temporal bone imaging where the fine detail structures of the inner ear are also difficult to resolve with standard imaging techniques.

  • Patent number: 9959486
    Abstract: A single level machine-learnt classifier is used in medical imaging. A gross or large structure is located using any approach, including non-ML approaches such as region growing or level-sets. Smaller portions of the structure are located using ML applied to relatively small patches (small relative to the organ or overall structure of interest). The classification of small patches allows for a simple ML approach specific to a single scale or at a voxel/pixel level. The use of small patches may allow for providing classification as a service (e.g., cloud-based classification) since partial image data is to be transmitted. The use of small patches may allow for feedback on classification and updates to the ML. The use of small patches may allow for the creation of a labeled library of classification partially based on ML. Given a near complete labeled library, a simple matching of patches or a lookup can replace ML classification for faster throughput.

  • Patent number: 9915642
    Abstract: A method of assessing a tissue sample includes the steps of: 1) splitting source electromagnetic radiation into: a) sample arm radiation directed in a Z direction toward a sample thereby illuminating the sample at a first selected XY coordinate pair of the sample, and b) reflector arm radiation directed toward a reflector so that the reflector arm radiation travels a path length; 2) interfering sample-scattered electromagnetic radiation with reflector-reflected electromagnetic radiation thereby establishing an interference pattern associated with the sample; 3) comparing the sample interference pattern to a reference interference pattern; and 4) reaching a conclusion about the sample based on the comparison.

  • Patent number: 9915520
    Abstract: An optical instrument including at least a first and second wavelength swept vertical cavity laser (VCL) sources. The wavelength sweeping ranges spanned by the first and second VCL sources may differ with a region of spectral overlap. The first and second VCL sources may be operable under different modes of operation, wherein the modes of operation differ in at least one of: sweep repetition rate, sweep wavelength range, sweep center wavelength, and sweep trajectory. A VCL source may also exhibit sweep-to-sweep variation. Apparatus and methods are described for aligning sample signal data from the first VCL and sample signal data from the second VCL to generate output digital data. The output digital data is aligned with respect to at least one of: wavelength, wavenumber, and interferometric phase. The apparatus and methods can also be used to phase stabilize successive sweeps from the same VCL source or wavelength swept source.

  • Patent number: 9901254
    Abstract: The invention relates to systems and methods for tomographic imaging of a subject comprising diffuse media by converting measurements of electromagnetic radiation, e.g., fluorescent light, obtained in free space exterior to the subject into data that would be measured if the subject were surrounded by an infinite and homogeneous diffusive medium, e.g., a medium with optical properties equal to the average optical properties of the subject. After applying a transformation to convert measurements to virtually-matched values, propagation of light is simulated from the index-matched surface to a set of virtual detectors exterior to the subject and arranged in a geometrically advantageous fashion, for example, in a planar array, thereby facilitating the use of fast reconstruction techniques.

  • Patent number: 9880268
    Abstract: A method is presented for correcting errors in a 3D scanner. Measurement errors in the 3D scanner are determined by scanning each of a plurality of calibration objects in each of a plurality of sectors in the 3D scanner's field of view. The calibration objects have a known height, a known width, and a known length. The measurements taken by the 3D scanner are compared to the known dimensions to derive a measurement error for each dimension in each sector. An estimated measurement error is calculated based on scans of each of the plurality of calibration objects. When scanning target objects in a given sector, the estimated measurement error for that sector is used to correct measurements obtained by the 3D scanner.
