  • Patent number: 11366208
    Abstract: In some embodiments, ultrasound receive beamforming yields beamformed samples, based upon which spatially intermediate pixels (232, 242, 244) are dynamically reconstructed. The samples have been correspondingly derived from acquisition through respectively different acoustic windows (218, 220). The reconstructing is further based on temporal weighting of the samples. In some embodiments, the sampling is via synchronized ultrasound phased-array data acquisition from a pair of side-by-side, spaced apart (211) acoustic windows respectively facing opposite sides of a central region (244) to be imaged. In particular, the pair is used interleavingly to dynamically scan jointly in a single lateral direction in imaging the region. The acquisition in the scan is, along a synchronization line (222) extending laterally across the region, monotonically progressive in that direction. Rotational scans respectively from the window pair are synchronizable into a composite scan of a moving object.

  • Patent number: 11350907
    Abstract: A multimodal intravascular catheter system includes a catheter with an optical channel and an electrical channel. A distal end of the catheter includes an optical element and an ultrasonic transducer, which are oriented orthogonally to a rotational axis of the catheter. A motor drive unit (MDU) is coupled to a proximal end of the catheter and includes a drive motor to rotate the catheter. The optical channel directs light from a pulsed UV laser source to the optical element, and returns an optical fluorescence signal from the optical element. A photodetector converts the returned optical fluorescence signal into an electrical fluorescence signal. An intravascular ultrasound (IVUS) processor is coupled to the ultrasonic transducer through the electrical channel, wherein the IVUS processor generates a drive signal for the ultrasound transducer, and processes echo information returned from the ultrasound transducer. Finally, a digitizer samples the electrical fluorescence signal and associated echo information.
