  • Patent number: 10265045
    Abstract: A medical diagnostic imaging apparatus according to an embodiment includes control circuitry. The control circuitry obtains three-dimensional medical image data of acquiring an area of an object. The control circuitry defines a setting region on the three-dimensional medical image data. The control circuitry divides the setting region into a region of interest and a region other than that by at least a single boundary position. The control circuitry generates, from the three-dimensional medical image data, an image in which the region of interest and the region other than that are distinguished from each other. The control circuitry calculates information about at least one of a volume of and a motion index of the region of interest. The control circuitry displays the calculated information for the region of interest in the image.

    Abstract: A method for medical image segmentation. The method includes accessing and updating a knowledge-base in accordance with embodiments of the present invention. The techniques include: receiving a medical image and computing a sparse landmark signature based on the medical image content. Next, a knowledge-base is searched for representative matches to form a base set, wherein the base set comprises a plurality of reference image sets. A portion of the plurality of reference image sets of the base set is deformed to generate mappings from the base set to the medical image set. Finally a weighted average segmentation for each structure of interest of the medical image set is determined.

  • Patent number: 10262106
    Abstract: A method of creating medical documentation uses selection of images representing synonyms for complex medical concepts. The images can be of two types, one corresponding to a parameter or Key in a Key/Value pair and the other corresponding to possible values of the selected parameter or Key. The user first selects an image or portion thereof corresponding to the parameter they wish to record observations, such as the heart or a valve of the heart. A set of images representing possible values of the parameter is then displayed e.g., images representing possible murmurs the selected valve may have. The user selects the image representing the value corresponding to the observation of the patient. A document is created by recording either the Key/Value image pairs or, alternative, text representing the synonyms for the images. Other methods of recording the document are possible, such as instantiating a set of class objects.

  • Patent number: 10251594
    Abstract: Minimally-invasive spinal inventions are often performed using fluoroscopic imaging methods, which can give a real-time impression of the location of a surgical instrument, at the expense of a small field of view. When operating on a spinal column, a small field of view can be a problem, because a medical professional is left with no reference vertebra in the fluoroscopy image, from which to identify a vertebra, which is the subject of the intervention. Identifying contiguous vertebrae is difficult because such contiguous vertebrae are similar in shape. However, characteristic features, which differentiate one vertebra from other vertebra, and which are visible in the fluoroscopic view, may be used to provide a reference.

  • Patent number: 10197697
    Abstract: Systems, methods, and software for modeling subterranean formation permeability are described. In some aspects, a method of training a subterranean formation permeability model based on NMR data includes accessing relaxation-time distributions generated from NMR measurements associated with a subterranean region. Multiple sets of principal components are generated from the relaxation-time distributions. Each set of principal components represents a respective one of the relaxation-time distributions. Parameters for weighted radial basis functions are computed based on the sets of principal components. A subterranean formation permeability model that includes the weighted radial basis functions and the computed parameters is produced.

  • Patent number: 10194883
    Abstract: Disclosed are a radiographic imaging device and a radiographic imaging method which appropriately set an irradiation condition of radiation according to the presence or absence of an implant in a breast. An implant information acquisition unit 80 acquires implant information representing whether or not an implant is included in a breast M as a subject. An irradiation condition setting unit 82 sets, based on the implant information, a first irradiation condition C1 for irradiating the breast M with radiation when an implant is present and a second irradiation condition C2 for irradiating the breast M with radiation when an implant is absent. A radiation source drive control unit 70 drives an X-ray source 50 under the irradiation condition set by the irradiation condition setting unit 82 to irradiate the breast M with radiation.
