  • Patent number: 10786227
    Abstract: The ultrasound examination system automatically detects a lesion, based on a dynamic image including a plurality of frame arrays that are temporally continuous and are output from the ultrasound examination apparatus with an ultrasonic probe being manipulated. Detection accuracy of the ultrasound examination system can be increased. A feature extractor in a frame checker extracts cubic higher-order local autocorrelation features from each frame of a plurality frames that constitute a dynamic image of a human body part as obtained from an ultrasound examination apparatus while an examiner manipulates an ultrasonic probe on the examinee. A final determinator determines that the frame in question is a normal frame when a speed determinator determines that the speed of the ultrasonic probe is not a normal speed even though the frame in question can be determined as an abnormal frame containing a lesion.

  • Patent number: 10774003
    Abstract: Provided herein is a method for forming a periodic microstructure on a surface of zirconia-based ceramics, which are not easily mechanically workable, without causing thermal adverse effects. A zirconia-based ceramic having a surface periodic microstructure is also provided. A linearly or circularly polarized laser beam is irradiated to a zirconia-based ceramic surface, and periodic irregularities are formed in a spot of the laser beam. Stripe-pattern irregularities parallel to the direction of polarization can be formed in a spot of a laser beam by irradiating a linearly polarized ultrashort pulsed-laser beam to a zirconia-based ceramic surface. A mesh-like raised region and a dot-like recessed region can be periodically formed by irradiating a circularly polarized ultrashort pulsed-laser beam to a ceramic surface.
