Abstract
A system for use with ultrasound transducers on a catheter and connected to different respective channels includes circuitry and a processor. The circuitry is configured to receive a signal, which includes transduction of ultrasound reflections, over any given one of the channels, and to receive respective noise-signals, which include less transduction of ultrasound reflections than the signal, over a group of others of the channels. The processor is configured to receive the signal and the noise-signals from the circuitry, and to reduce noise in the signal, by, based on the noise-signals, computing, for the given channel, one or more noise-estimation functions, each of which is applicable to a respective subset of the noise-signals so as to return an estimate of noise received over the given channel while the subset of the noise-signals were received, using the noise-estimation functions, computing an estimated-noise signal, and subtracting the estimated-noise signal from the signal.
