    • An acoustical imaging catheter adapted to be used with a drive and control system wherein the system can be automatically advised to compensate for different characteristics of different acoustical imaging catheters used on the drive and control system. The catheter includes an elongated sheath (12) having a proximal end (7) and a distal end. A lumen is disposed within the sheath (12). A drive shaft (18) has an acoustic transducer disposed on the distal end thereof. The drive shaft and the transducer are disposed in the lumen of the sheath. An indicia bearing surface (2) is disposed on the sheath (12). The indicia bearing surface (2) is encoded with identification and characteristics especially related to the catheter and transducer. The indicia bearing surface is adapted to be read by a sensor associated with the control system to enable the control system to compensate for the identification and characteristics of the catheter being used.
    • 一种适合与驱动和控制系统一起使用的声学成像导管,其中该系统可被自动建议补偿驱动和控制系统上使用的不同声学成像导管的不同特性。 导管包括具有近端(7)和远端的细长护套(12)。 内腔设置在护套(12)内。 驱动轴(18)具有设置在其远端上的声学换能器。 驱动轴和换能器设置在护套的内腔中。 标记支承表面(2)设置在护套(12)上。 标记支承表面(2)编码有特别与导管和换能器相关的识别和特征。 标记支承表面适于由与控制系统相关联的传感器读取,以使控制系统能够补偿正在使用的导管的识别和特征。
