  • Patent number: 10271817
    Abstract: A regurgitant orifice of a valve is detected. The valve is detected from ultrasound data. An anatomical model of the valve is fit to the ultrasound data. This anatomical model may be used in various ways to assist in valvular assessment. The model may define anatomical locations about which data is sampled for quantification. The model may assist in detection of the regurgitant orifice using both B-mode and color Doppler flow data with visualization without the jet. Segmentation of a regurgitant jet for the orifice may be constrained by the model. Dynamic information may be determined based on the modeling of the valve over time.

  • Patent number: 10231637
    Abstract: In a system and method for non-contact mapping of an anatomic structure, the spatial position of an electrode is determined independent of a previously generated three-dimensional model of the anatomic structure. A position of the electrode relative to a boundary surface of the model is determined, along with a corresponding point on the boundary surface of the three-dimensional model that is closest to the relative electrode position. A signed distance (d) of the relative electrode position from the corresponding closest point on the boundary surface is determined, wherein a positive signed distance indicates the relative electrode position is exterior to the model. In such an instance, the boundary surface is perturbed (e.g., expanded outward) at least in part as a function of the signed distance (d) until the relative electrode position lies interior to the model.

  • Patent number: 10076652
    Abstract: Methods to use medical imaging to monitor the molecule penetration into CNS during ultrasound-mediated delivery are disclosed. The method states a two-step process to predict the amount of molecular penetration which is based on the observation of medical imaging. The first is to propose a unified exposure input to unify the exposure condition so as to build a transferred relation to imaging index. The second is to propose a unified imaging index to unify the imaging readout so as to build a reliable transferred relation to molecular concentration. Linking these two, the molecular penetration induced by ultrasound irradiation can be estimated from medical imaging with ultrasound exposure conditions and molecular sizes.

  • Patent number: 9986923
    Abstract: What is disclosed is a system and method for selecting a region of interest for extracting physiological parameters from a video of a subject. In one embodiment the present method involves performing the following. First, time-series signals are received which have been generated by having processing image frames of a video of a subject captured using a single band video camera with a bandpass filter with a pass band in a wavelength range of 495-565 nm and/or 800-1000 nm. The regions of interest are areas where a plethysmographic signal can be detected by the camera. Each time-series signal is associated with a different region of interest. A signal strength is then calculated for each of the time-series signals. The region associated with the time-series signal having a highest signal strength is selected. The time-series signal associated with the selected region can be processed to extract a videoplethysmographic (VPG) signal containing physiological parameters.
