  • Patent number: 11911210
    Abstract: A system includes an image guidance system with a memory with computer executable instruction, a processor configured to execute the computer executable instructions, and a display. The computer executable instructions cause the processor to: receive a three-dimensional model of vasculature from an ultrasound imaging system, receive a real-time optical feed of an interior of a cavity from an optical camera-based guidance system, receive a first tracking signal indicative of a first spatial location of a probe of the ultrasound imaging system, receive a second spatial location of the optical camera-based guidance system, and overlay the optical feed with the three-dimensional model based on the first and second tracking signals. The display is configured to visually present the optical feed with the three-dimensional model overlaid thereover.

  • Patent number: 11559281
    Abstract: An imaging system includes transmit circuitry, a transducer array with an array of capacitive micromachined ultrasonic transducer elements, a beamformer, a decoder and a display. The transmit circuitry includes a signal generator and at least one excitation coding scheme. The transmit circuitry combines an excitation signal generated by the signal generator with an excitation coding scheme of the at least one excitation coding scheme, generating a coded excitation signal. The array of transducer elements is excited with the coded excitation signal to emit ultrasound signals. The coding scheme does not introduce heating on the capacitive micromachined ultrasonic transducer elements. The array of ultrasonic transducer elements receives echo signals produced in response to the ultrasound signals interacting with structure and generates electrical signals indicative thereof.
