  • Patent number: 11490830
    Abstract: Method and systems provide a tool to quantify sensory maps of the brain. Cortical surfaces are conformally mapped to a topological disk where local geometry structures are well preserved. Retinotopy data are smoothed on the disk domain to generate a curve that best fits the retinotopy data and eliminates noisy outliers. A Beltrami coefficient map is obtained, which provides an intrinsic conformality measure that is sensitive to local changes on the surface of interest. The Beltrami coefficient map represents a function where the input domain is locations in the visual field and the output is a complex distortion measure at these locations. This function is also invertible. Given the boundaries and the Beltrami map of a flattened cortical region, a corresponding visual field can be reconstructed. The Beltrami coefficient map allows visualization and comparison of retinotopic map properties across subjects in the common visual field space.

  • Patent number: 11439848
    Abstract: A template matching is performed on two fluoroscopic images by using a template image prepared in advance and a position corresponding to a high matching score is listed as a candidate for the position of a marker 29. From two lists of the candidates of the position of the marker 29, the lengths of common vertical lines for all combinations are calculated. Then, the position of the marker 29 is detected based on the matching score and the common vertical line. Then, based on the detected position of the marker 29, an amount of a proton beam to be irradiated to a target is controlled. Therefore, a tracking target can be accurately detected even when the conditions for X-ray fluoroscopy is severe, e.g., a thick object.

  • Patent number: 11395642
    Abstract: This disclosure relates generally to bio-signal detection, and more particularly to method and system for non-contact bio-signal detection using ultrasound signals. In an embodiment, the method includes acquiring an in-phase I(t) baseband signal and a quadrature Q(t) baseband signal associated with an ultrasound signal directed from the sensor assembly towards the target. Magnitude and phase signals are calculated from the in-phase and quadrature baseband signals, and are filtered by passing through a band pass filter associated with a predefined frequency range to obtain filtered magnitude and phase signals. Fast Fourier Transformation (FFT) of the filtered magnitude and phase signals is performed to identify frequency of dominant peaks of spectrum of the magnitude and phase signals in the ultrasound signal. Value of the bio-signal associated with the target is determined based on weighted values of the frequency of the dominant peaks of the magnitude and phase signals.
