SYSTEM AND METHOD FOR DETERMINING A TRANSFER FUNCTION

摘要

A system and method is provided for using ultrasound data backscattered from vascular tissue to estimate the transfer function of a catheter (including components attached thereto -- e.g., IVUS console, transducer, etc.). Specifically, in accordance with a first embodiment of the present invention, a computing device (110) is electrically connected to a catheter (120) and used to acquire RF backscattered data from a vascular structure (e.g., a blood vessel, etc.). The backscattered ultrasound data is then used, together with an algorithm, to estimate the transfer function. The transfer function can then be used (at least in a preferred embodiment) to calculate response data for the vascular tissue (i.e., the tissue component of the backscattered ultrasound data).
