1. An ultrasound imaging system, comprising: an interface for receiving user input; a controller coupled to the interface, the controller being adapted and configured to adjust parameters for a catheter-based ultrasound probe in response to received user input; and a catheter-based ultrasound probe coupled to the controller, wherein the controller is programmed to: receive a user request for a desired imaging depth; automatically determine an imaging frequency that corresponds to the desired imaging depth; adjust the frequency of signals applied to the catheter-based ultrasound probe to the determined imaging frequency that corresponds to the desired imaging depth; automatically process a first image of a feature of interest imaged at the determined imagine frequency to measure image resolution; adjust the frequency of signals applied to the catheter-based ultrasound probe by a delta-frequency; automatically process a second image of the feature of interest imaged at the delta-frequency adjusted imagining frequency to measure image resolution; automatically compare the measured resolution of the first image to the measured resolution of the second image; and automatically adjust the frequency of signals applied to the catheter-based ultrasound probe to the adjusted imaging frequency if the measured resolution of the second image is better than the measured resolution of the first image.
