Abstract
A method and system is provided for using backscattered data and known parameters to characterize vascular tissue. Specifically, methods and devices for identifying information about the imaging element used to gather the backscattered data are provided in order to permit an operation console having a plurality of Virtual Histology classification trees to select the appropriate VH classification tree for analyzing data gathered using that imaging element. In order to select the appropriate VH database for analyzing data from a specific imaging catheter, it is advantageous to know information regarding the function and performance of the catheter, such as the operating frequency of the catheter and whether it is a rotational or phased-array catheter. The present invention provides a device and method for storing this information on the imaging catheter and communicating the information to the operation console. In addition, information related to additional functions of the catheter may also be stored on the catheter and used to further optimize catheter performance and/or select the appropriate Virtual Histology classification tree for analyzing data from the catheter imaging element.

88. A method, comprising:
-
providing a catheter having an RFID chip located adjacent a proximal end of the catheter and a transducer adjacent a distal end of the catheter, the RFID chip storing information related to a function of the catheter; accessing information related to a function of the catheter stored on the RFID chip using the RFID scanner of a catheter interface device in response to the RFID chip being positioned within a transmitting distance from the RFID scanner, wherein the catheter interface device is a pullback device configured to control longitudinal movement of the catheter, including the transducer, through a vessel; identifying at least one operating characteristic related to the function of the catheter based on the information related to the function of the catheter accessed from the RFID chip, the at least one operating characteristic including an operating parameter of the transducer; and using the at least one operating characteristic related to the function of the catheter to control operation of the transducer. - View Dependent Claims (89, 90, 91, 92, 93, 94, 95, 96, 97, 98)
