  • Patent number: 10368832
    Abstract: Issuance of ultrasound pulses to a volume and receiving echo data is followed by estimating, based on the received data, center frequency subvolume-by-subvolume. Distinguishing between heart and lung tissue occurs based on a result of the estimating, and may include automatically identifying a spatial boundary (332) between the heart and lung tissue (324, 328), or a user display of center frequencies that allows for visual distinguishing. The issuance can include issuing, ray line by ray line, pair-wise identical, and/or pair-wise mutually inverted, ultrasound pulses. Center frequency calculations may be made for incremental sampling locations of respective imaging depth along each of the A-lines generated from echo data of the rays. The distinguishing might entail averaging center frequencies for locations along an A-line, and applying a central frequency threshold to the average. The leftmost of the qualifying A-lines, i.e.

  • Patent number: 10362961
    Abstract: Systems and methods for magnetic resonance imaging (“MRI”), in which accurate and conspicuous visualization of vascular calcifications and other bony structures can be achieved. An MRI system is operated to perform a pulse sequence that generates substantially similar signal intensity from soft tissues (e.g. muscle, fat, blood) within the body. For instance, blood can be rendered to have a signal intensity that is substantially similar to the vessel wall, while fat and muscle are rendered to appear substantially similar to the vessel wall. With this “neutral” contrast, arterial calcifications, which appear dark due to their low proton density, can be more readily and efficiently visualized by an interpreting physician.

  • Patent number: 10314512
    Abstract: In a magnetic resonance method and apparatus for determining an item of deformation information of an examination object that exhibits a cyclical movement within an examination subject, a spatial magnetization pattern is generated in an MR scanner, and MR signals are acquired from the subject during at least two cycles of the cyclical movement, with the spatial magnetization exhibiting differences in a subsequent cycle of the movement compared to an earlier cycle. Segmented subsequent MR images are acquired in a subsequent cycle and the examination object is localized therein. This localization of the examination object is then used to localize the examination object in segmented earlier MR images from the earlier cycle, and the item of deformation information is determined in a spatial direction from the segmented earlier MR images.

  • Patent number: 10307136
    Abstract: The present invention relates to a monitoring apparatus (100, 200) for monitoring a structural change in an object (280, 340), such as a heart wall tissue. Tissue at first and second locations exhibits first and second velocities. The monitoring apparatus (100, 200) comprises an ultrasound signal providing unit for providing ultrasound signals of the object (280, 340) for different times. The monitoring apparatus (100, 200) further comprises a discontinuity determination unit (120, 220) for determining a discontinuity of the first and second velocities based at least in part on a change in time of tissue velocity differences and of tissue velocity sums. From the discontinuity an ablation depth can be determined, which is an important parameter while performing an ablation procedure.

  • Patent number: 10310097
    Abstract: Apparatus, techniques and systems are described for facilitating identification of a target area during a probe-guided radio-localization surgical procedure. The described apparatus, techniques and systems can be used to implement a nuclear-uptake mode controller integrated into a probe to allow a user to instantly switch between multiple nuclear-uptake modes directly from the probe hand-piece. For example, a nuclear-uptake mode controller integrated into the probe can be used to instantly switch between a high-sensitivity nuclear-uptake mode and a high-resolution nuclear-uptake mode to effectively identify the target area in the presence of interfering nuclear signals by better matching the probe's nuclear detection parameters to a search task for that target area.

  • Patent number: 10299717
    Abstract: Described herein are systems and methods for detecting a stress level of a user. In one embodiment, a system includes an inward-facing head-mounted thermal camera (CAM) and a computer. CAM takes thermal measurements of a region on a periorbital area (THROI1) of the user. The computer generates feature values based on THROI1, and utilizes a model to detect the stress level based on the feature values. The model was trained based on: previous THROI1 taken while the user was under elevated stress, and other previous THROI1 taken while the user was not under elevated stress. Some embodiments may utilize additional thermal cameras that take thermal measurements of other regions on the face, which may be utilized to detect the stress level.

  • Patent number: 10285622
    Abstract: An MR Spectroscopy (MRS) system and approach is provided for diagnosing painful and non-painful discs in chronic, severe low back pain patients (DDD-MRS). A DDD-MRS pulse sequence generates and acquires DDD-MRS spectra within intervertebral disc nuclei for later signal processing and diagnostic analysis. An interfacing DDD-MRS signal processor receives output signals of the DDD-MRS spectra acquired and is configured to optimize signal-to-noise ratio by an automated system that selectively conducts optimal channel selection, phase and frequency correction, and frame editing as appropriate for a given acquisition series. A diagnostic processor calculates a diagnostic value for the disc based upon a weighted factor set of criteria that uses MRS data extracted from the acquired and processed MRS spectra for multiple chemicals that have been correlated to painful vs. non-painful discs. A display provides an indication of results for analyzed discs as an overlay onto a MRI image of the lumbar spine.

  • Patent number: 10271801
    Abstract: Disclosed are a radiation imaging system, an image processing device, and a non-transitory computer-readable recording medium having an image processing program recorded thereon which facilitate the confirmation of a positional relationship between an object of interest and a biopsy needle. A control unit of a console reconstructs a projection image obtained by tomosynthesis imaging to generate a tomographic image parallel (an x-y-axis direction) to an imaging surface in a state where a needle is inserted into a breast, and specifies an image of an object of interest from the tomographic image. The control unit generates a sectional image which includes the specified image of the object of interest and an image of the needle and intersects the imaging surface. The control unit generates an image of the needle from the projection image, synthesizes the generated image of the needle into the sectional image while aligning, and displays the sectional image.
