摘要:
The disclosed technology relates to imaging catheters. A method is provided that includes: receiving, from a plurality of transducers disposed on a catheter probe, a corresponding plurality of analog signals selectively sampling the plurality of analog signals multiplexing to produce a sequence of samples and transmitting the sequence of samples to a receiver circuit. The receiver circuit includes a clock an analog to digital converter (ADC) in communication with the clock and a sampling phase correction circuit in communication with the clock and the ADC. The method further includes: determining optimum sampling times based on measured signal delays associated with the system adjusting a phase of the clock based on the measured signal delays and communicating the phase-adjusted clock to the transmitter circuit for the selective sampling of the analog signals. Certain embodiments of the disclosed technology may further be utilized in conjunction with beamforming.
