  • Patent number: 9814549
    Abstract: A flexible arch model (FAM) is computed to capture and parameterize the variations of the multiple real dental arches in a training set to reconstruct missing teeth in a patient's dental anatomy. Building the FAM includes acquiring multiple sets of digitized dental arches with a pair of maxillary (upper) and mandibular (lower) jaws in the right relative position and gathering a pre-defined set of landmark points on the occlusal surface of each arch all in the same order and same corresponding positions across multiple samples. The gathered vectors of landmark points are used to perform statistical modeling (e.g. Principal Component Analysis) to create a linear subspace of the feature points with the basis of principal components (when PCA is used) found during the procedure. An arbitrary set of landmark points on a pair of upper and lower arches can be reconstructed by a linear combination of the principal components within a reasonable range of variations captured from the training samples.

  • Patent number: 9788751
    Abstract: An electrophysiology map, for example a map of arrhythmic substrate, can be generated by acquiring both geometry information and electrophysiology information pertaining to an anatomical region, and associating the acquired geometry and electrophysiology information as a plurality of electrophysiology data points. A user can select two (or more) electrophysiological characteristics for display, and can further elect to apply various filters to the selected electrophysiological characteristics. The user can also define various relationships (e.g., Boolean ANDs, ORs, and the like) between the selected and/or filtered characteristics. The user-selected filtering criteria can be applied to the electrophysiology data points to output various subsets thereof. These subsets can then be graphically rendered using various combinations of colorscale, monochrome scale, and iconography, for example as a three-dimensional cardiac electrophysiology model.

  • Patent number: 9784725
    Abstract: A method to measure the volume of fluid present that relies on the pattern of light refraction as it passes though an airway surface liquid (ASL) meniscus. The method comprises allowing epithelial cells to grow on a membrane in a well so as to form a fluid meniscus about the perimeter of the well. The well is then illuminated by a light source. The illuminated cells in the well are then optically imaged by a scanner, a flat bed optical scanner, a camera, or any device capable of imaging. Microscopy may be used but is not needed, and high powered microscopy is certainly not needed. Then the imaging information from the cells in the well is used to determine a property of the meniscus in the well. Specifically, the imaging information can be analyzed to determine the dimensions, shape, and/or volume of the meniscus and the fluid in the well.

    Abstract: A charged particle detector array includes one or more pairs of super modules, one super module in a pair of super modules is positioned above a volume of interest (VOI), and the other super module in the pair of super modules is positioned below the VOI. This calibration technique first calibrates individual super modules in the one or more pairs of super modules while treating each super module being calibrated as a rigid body. Each super module in the one or more pairs of super modules further includes multiple vertically-stacked modules, and each module in the multiple vertically-stacked modules is composed of multiple layers of drift tubes. The calibration technique then calibrates individual modules in each of the super modules while treating each module being calibrated as a rigid body.

  • Patent number: 9782106
    Abstract: In a method and apparatus, magnetic resonance angiography images of an examination volume of a patient are obtained using time-of-flight angiography in a magnetic resonance scanner. By continuous recording, a number of two-dimensional slice images covering the examination volume along an axial direction are acquired in a slice-by-slice layer-wise, such as with overlapping. The slice images are divided into groups of, in each case, a predetermined number of consecutive slice images in the axial direction. A maximum intensity projection image is determined for each group, and the angiography images are determined as the maximum intensity projection images and/or dependent on the maximum intensity projection images.

  • Patent number: 9779503
    Abstract: A method measures the efficacy of a stain/tissue combination for histological tissue image data comprising a set of pixels. The measures of efficacy comprise a statistical measure of clustering performance of the different stain/tissue combinations in the Maxwellian Chromaticity plane, and a representative density of the stain/tissue combinations in the density maps. The method captures histological tissue image data using a light absorbent stain; transforms the histological tissue image data to optical density data; projects the optical density data to the Maxwellian Chromaticity plane; identifies at least one reference color using a statistical technique; inverts the reference color to form a color mixing matrix; derives a density map; derives a statistical measure for the clustering performance of the different stain/tissue combinations in the Maxwellian Chromaticity plane; and finds a representative density of the stain/tissue combinations in the density maps.

  • Patent number: 9779504
    Abstract: Method for locating anomalous features in medical images in which medical images are supplied by an external source. A sequence of specific measurements is executed on the supplied data to obtain image-related metrics. The metrics are compared to corresponding values in a database resulting in an anomalous/not anomalous determination. Anomalous determinations are presented to the test operator for analysis along with supplemental historical data. In application to all types of medical imagery, potential anomalies are located resulting in an efficient and accurate diagnosis. For paired body parts having symmetrical properties, as a pre-screening stage, a line of symmetry between the body parts is determined and symmetric regions of the two body parts on opposite sides of the determined line of symmetry are analyzed for differences. The metric comparison using the database is performed between both symmetric regions only when differences between the symmetric regions of the subject medical image are present.

  • Patent number: 9779492
    Abstract: Automatically determining image quality of a machine generated image may generate a local saliency map of the image to obtain a set of unsupervised features. The image is run through a trained convolutional neural network (CNN) to extract a set of supervised features from a fully connected layer of the CNN, the image convolved with a set of learned kernels from the CNN to obtain a complementary set of supervised features. The set of unsupervised features and the complementary set of supervised features are combined, and a first decision on gradability of the image is predicted. A second decision on gradability of the image is predicted based on the set of supervised features. Whether the image is gradable is determined based on a weighted combination of the first decision and the second decision.
