  • Patent number: 9977236
    Abstract: This optical scanning method yields a high quality image. An emission end of an optical fiber is displaced two-dimensionally to scan light emitted from the optical fiber, the emission end being displaced with an optical scanning actuator that includes a first driver and a second driver for driving the emission end in different directions. A circular scanning area is scanned by controlling, with a driver controller, a first drive signal supplied to the first driver and a second drive signal supplied to the second driver so as to rotate a scanning pattern of the light while causing the scanning pattern to reciprocate repeatedly in a nearly parallel manner with constant length.

    Abstract: In a magnetic resonance (MR) apparatus and a method for operating an MR apparatus, MR data are acquired and evaluated with regard to multiple tentative signal models for producing a parameter map based on one of those signal models. The parameter map shows multiple parameters that have respective effects on the MR data. Each tentative signal model is initially analyzed to determine whether any of the parameters used therein can be assumed to be at least locally constant, and the initially analyzed tentative signal model is then subjected at least to a quality of fit analysis. The tentative signal model having at least the best quality of fit analysis result is then used to generate a parameter map that is displayed at a display monitor.

  • Patent number: 9958521
    Abstract: A system that determines an invariant magnetic-resonance (MR) signature of a biological sample is disclosed. During operation, the system determines a magnetic-resonance (MR) model of voxels in a biological sample based on differences between MR signals associated with the voxels in multiple scans and simulated MR signals. The MR signals are measured or captured by an MR scanner in the system during multiple MR scans, and based on scanning instructions, and the simulated MR signals for the biological sample are generated using the MR model and the scanning instructions. Moreover, the system iteratively modifies the scanning instructions (including a magnetic-field strength and/or a pulse sequence) in the MR scans based on the differences until a convergence criterion is achieved. Then, the system stores, in memory, an identifier of the biological sample and a magnetic-field-strength-invariant MR signature of the biological sample that is associated with the MR model.

  • Patent number: 9895127
    Abstract: Systems and methods of object reconstruction from x-ray imaging include receiving an input of a first angulation for a first x-ray image. A first score representative of a quality of a reconstruction of an object from an x-ray image acquired at the first angulation is calculated. The first x-ray image is acquired at the first angulation. An input of a second angulation for a second x-ray image is received. A second score representative of the quality of the reconstruction of the object from the first x-ray image and an x-ray image acquired at the second angulation is calculated. The second x-ray image is acquired at the second angulation. The object is reconstructed from the first x-ray image and the second x-ray image.

  • Patent number: 9888968
    Abstract: A method and system for automated decision support for treatment planning of arterial stenoses is disclosed. A set of stenotic lesions is identified in a patient's coronary arteries from medical image data of the patient. A plurality of treatment options are generated for the set of stenotic lesions, wherein each of the plurality of treatment options corresponds to a stenting configuration in which one or more of the stenotic lesions are stented. For each of the plurality of treatment options, predicted hemodynamic metrics for the set of stenotic lesions resulting from the stenting configuration corresponding to that treatment option are calculated.

  • Patent number: 9892521
    Abstract: A console structure in an X-ray imaging system performs image processing of plural radiation images formed by an X-ray imaging apparatus having an active pixel area with pixels for detecting a radiation image of a body. The plural radiation images are formed by imaging one object in the body with a time interval. The console structure acquires the radiation images. An information controller obtains field information of a position of an exposure field which is associated with each one of the radiation images and automatically set in the active pixel area according to a position of the body being positioned for automatic exposure control in the X-ray imaging apparatus before imaging. A matching unit performs position matching according to the field information to match the position of the body in the plural radiation images between plural display images corresponding to respectively the plural radiation images.

  • Patent number: 9886748
    Abstract: Methods and systems are described for removing reflective artifacts from an imaging. A first volumetric model and a second volumetric model of the same object are accessed from a computer-readable memory. The orientation and scale of at least one of the two models is repeatedly and automatically adjusted until an optimized orientation and scale is determined that correlates the first volumetric model and the second volumetric model. The second volumetric model is then overlaid onto the first volumetric model. Any data points in the first volumetric model that extend beyond a surface of the second volumetric model are detected and removed to create an artifact-reduced volumetric model.

    Abstract: Robotic navigation is provided in nuclear probe imaging. Adaptive reconstruction is provided. A measure of quality of the reconstruction is used as a feedback to determine when sufficient sampling has occurred. For example, once a pre-determined number of separate lesions are indicated in the reconstruction, the quality of the reconstruction is considered sufficient.

  • Patent number: 9870615
    Abstract: Locating morphology in a tissue sample is achieved with devices and methods involving storage of a plurality of feature vectors, each associated with a specific named superpixel of a larger image of a tissue sample from a mammalian body. A microscope outputs, in some embodiments, a live image of an additional tissue sample or a digitized version of the output is used. At least one superpixel of the image is converted into a feature vector and a nearest match between the first feature vector and the plurality of stored feature vectors is made. A first name suggestion is then made based on the nearest match comparison to a store feature vector. Further, regions of interest within the image can be brought to a viewer's attention based on their past history of selection, or that of others.
