  • Patent number: 10987086
    Abstract: An intravascular ultrasound imaging system comprises a catheter having an elongated body having a distal end and an imaging core arranged to be inserted into the elongated body. The imaging core is arranged to transmit ultrasonic energy pulses and to receive reflected ultrasonic energy pulses. The system further includes an imaging engine coupled to the imaging core and arranged to provide the imaging core with energy pulses to cause the imaging core to transmit the ultrasonic energy pulses. The energy pulses are arranged in repeated sequences and the energy pulses of each sequence have varying characteristics. The reflected pulses may be processed to provide a composite image of images resulting from each different characteristic.
    Type: Grant

  • Patent number: 9693754
    Abstract: Systems and methods for image processing based on ultrasound data. The system may include an IVUS catheter configured to collect data vectors including ultrasound data and an imaging engine configured to process the ultrasound data of the data vectors. The imaging engine may receive the data vectors and divide the data vectors into different sets. The ultrasound data of each respective set may be averaged and then an envelope of each set may be detected. The envelopes of each set may then be averaged to generate an enhanced data vector which may be used to generate an image.
