  • Patent number: 10898109
    Abstract: A method for automatic identification of a measurement item is provided. The method comprises acquiring, via an image acquisition module, gray values of pixels of a specified section image corresponding to ultrasonic echoes generated by reflection of ultrasound waves by a tissue under examination; identifying, via an identification module, at least one measurement item corresponding to the specified section image based on the gray values of the pixels; and measuring, via a measuring module, a measurement item parameter of the specified section image based on the measurement item identified. Because the measurement item of a specified section image can be automatically identified based on the content thereof, the user does not need to move a trackball to select measurement items, and therefore efficiency is increased.

  • Patent number: 10856841
    Abstract: The ultrasonic imaging probe includes a proximal handle, a shaft extending distally from the handle, and an ultrasonic transducer attached to the distal end of the shaft. The shaft may define multiple bends to assist in properly positioning the transducer when the probe is inserted through the sinus of a patient. An ultrasound communications fiber extends through the probe to the transducer. A tube that may be used for dispensing an ultrasound gel extends out from the handle and follows the length of the shaft for dispensing ultrasound gel on the transducer and surrounding tissue. The ultrasonic transducer transmits ultrasonic waves and detects reflected ultrasonic waves for creating an image of structures within the tissue. A data cable extending proximally out from the handle is adapted to transmit the data from the reflected waves to a monitor, which produces a real-time image from the data.

  • Patent number: 10852446
    Abstract: A system and method for the measurement of radiation emitted from an in-vivo administered radioactive analyte. Gamma radiation sensors may be used to determine the proper or improper administration of a radioactive analyte. In some cases, the system employs a sensor having a scintillation material to convert gamma radiation to visible light, which enables embodiments of the sensor to be ex vivo. A light detector converts the visible light to an electrical signal. This signal is amplified and is processed to measure the captured radiation. Temperature of the sensor may be recorded along with this radiation measurement for temperature compensation of ex vivo embodiments. The sensor enables collection of sufficient data to support separate application to predictive models, background comparisons, or change analysis.
