Patent ID: 8808183

Claim:
A system for acquiring ultrasound response data, comprising: a catheter including at least one transducer and adapted to transmit an ultrasound signal and to receive a backscatter of said ultrasound signal, the catheter being sized and shaped for maneuvering through a vascular structure such that the catheter is positionable at a first location for acquiring first backscattered ultrasound data from a first portion of the vascular structure; and a processing system in communication with the catheter, the processing system configured to: estimate a first transfer function of the catheter based on at least a portion of the first backscattered ultrasound data, the first transfer function being independent of the vascular structure; and calculate first ultrasound response data based on the first transfer function such that the first ultrasound response data is independent of ultrasound data modifications resulting from the catheter.
