  • Patent number: 10258313
    Abstract: An ultrasonic intracranial sonothrombolysis pressure amplitude is pre-quantified by using an ultrasound-scanner control unit (110) having an increasing and/or decreasing mode and designed for: with respect to a current mode, interrogating a blockage site iteratively so as to progressively and respectively increase or decrease a pressure amplitude of ultrasound being emitted to the site at which bubbles (144) for oscillating that is caused by the emitted ultrasound are present; iteration to iteration, deriving, from echoes of the emitted ultrasound, a magnitude of an energy of a signal; and automatically identifying, for the quantifying, an iteration that, in comparison with a just-previous iteration, fails to increase the magnitude. The interrogating may span a region that contains or goes through: the obstruction; another part of the blood vessel; and bubble circulation within a neighboring vessel and a neighboring capillary (136).

  • Patent number: 10222461
    Abstract: A system for ultrasonic imaging utilizing multiple sets of transmit pulses differing in amplitude, frequency, phase, and/or pulse width. One embodiment has phase differences between the k transmit signal as 360 k degrees providing for constructive interference of the kth order harmonic pulse, while an amplitude modulation of each transmit profile is constant between sets. These sets of pulses are transmitted into media of interest and received echoes from these pulses are combined to form an averaged signal. The averaged pulses represent the net common mode signal received from each of the transmit sets. This combined signal set is used to reconstruct an ultrasound image based on broad beam reconstruction methodology.

  • Patent number: 9861287
    Abstract: Featured are methods, apparatus and devices for detecting a hematoma in tissue of a patient. In one aspect, such a method includes emitting near infrared light continuously into the tissue from a non-stationary near infrared light emitter and continuously monitoring the tissue using a non-stationary probe so as to continuously detect reflected light. The near infrared light is emitted at two distances from a brain of the patient, so the emitted light penetrates to two different depths. Such a method also includes applying a ratiometric analysis to the reflected light to distinguish a border between normal tissue and tissue exhibiting blood accumulation.
