  • Patent number: 10271810
    Abstract: An apparatus includes a positioning system and a patient reference sensor (PRS). The positioning system acquires a plurality of raw PRS readings over time, which can indicate the position and orientation of the PRS. A filter is configured to process the raw PRS readings and output filtered PRS readings. The filter outputs filtered PRS readings as a baseline value while the raw PRS readings stay within a predetermined range and output filtered PRS readings as unchanged raw PRS readings when the raw PRS readings reach or vary outside of the predetermined range. A motion compensation function generated based on at least the filtered PRS readings can be used to correct a subject position and orientation (P&O) to compensate for the motion of the moving region of interest over time.

  • Patent number: 10258246
    Abstract: MRI techniques seek to simultaneously measure physiological parameters in multiple directions, requiring the application of multiple encoding magnetic field gradient waveforms. The use of multiple encoding waveforms degrades the temporal resolution of the measurement, or may distort the results depending on the methodology used to derive physiological parameters from the measured data. The disclosed Direct Inversion Reconstruction Method (DiR) provides distortion-free velocity images with high temporal resolution, without changing the method of acquiring the phase data. The disclosed method provides a more stable and accurate recovery of phase-based dynamic magnetic resonance signals with higher temporal resolution than current state-of-the-art methods.

  • Patent number: 10136820
    Abstract: A method for evaluating treatment outcome in a patient having a genetic predisposition for a malignant neoplasm before clinical manifestation of the neoplasm can be seen radiographically. The method permits visualization of any tumor, whether located externally on a patient's body or located internally in the body, and as small as 2 mm in diameter, using a biomarker. The method uses biomarkers conjugated with nanoparticles which include but are not limited to quantum dots, with the conjugated form collectively termed functionalized nanoparticles, that are heated under specified conditions to produce a photoacoustic signal that is then visualized to locate and/or treat the tumor.

  • Patent number: 10130822
    Abstract: An implantable cardiac device that detects and protects against strong magnetic fields produced by MRI equipment is disclosed. The device has a magnetic field sensor for detecting the presence of a relatively weak static magnetic field (102, 110, 118, 122) of a level equivalent to that of a permanent magnet in the vicinity of the device. The device is switched from a standard operating mode (100) where the nominal functions of the device are active, to a specific protected MRI mode (114, 116) in the presence of a magnetic static field of a level corresponding to that emitted by MRI equipment. The device further temporarily switches the device from the standard operating mode (100) to an MRI stand-by state (108) when a magnetic field is detected by the magnetic field sensor such that a subsequent detection of a magnetic field switches the device from an MRI stand-by state to the specific protected MRI mode.

The method comprises: introducing into the patient a contrast enhancing agent; subjecting the patient to magnetic resonance imaging to obtain an image; and applying a 3-D autocorrelation function to a subdomain of interest of the image to obtain at least one 3-D autocorrelation spectrum. The method may further comprise comparing the at least one 3-D autocorrelation spectrum to a pre-existing 3-D autocorrelation spectrum that is characteristic for the pathological lesion. In one example, the methods and compositions may be useful for identifying and objectively characterizing amyloid plaque deposits characteristic of Alzheimer's Disease.

  • Patent number: 10117705
    Abstract: Methods and apparatus for optically recognizing tissue parameters during an energy-based tissue-sealing procedure involve grasping tissue with a tissue-sealing instrument, illuminating the grasped tissue or tissue adjacent to the grasped tissue with light, analyzing the light that is transmitted, scattered, or reflected by the tissue, and recognizing the tissue based on the result of analyzing the light. The wavelength of the light may be selected so that a vessel is sufficiently recognizable in tissue containing the vessel. A marker may also be introduced into fluid flowing in the vessel to increase the contrast between the vessel and tissue containing the vessel. Analyzing the light includes analyzing the spatial and spectral distribution of light. Analyzing the light may also include forming the light into an image of the illuminated tissue.
