Abstract:
1. A method for detecting a stenosis using ultrasound data, comprising the steps of: (a) generating ultrasound data reflected from an internal site using an ultrasound machine including an ultrasound transducer; (b) processing the ultrasound data using a vibration processor to identify tissue vibrations at the internal site, producing a tissue vibration signal from which any contribution to the tissue vibration from a source other than the stenosis at the internal site has been reduced, said tissue vibration signal providing an indication of the stenosis, wherein the step of producing the tissue vibration signal is implemented using the following steps: (c) outputting an indication of the tissue vibration signal to a user in a format perceptible to the user, wherein the indication conveys to the user that a stenosis is present at the internal site.
