專利摘要(英)
An ultrasonic echo detection system and its method for catheters, suitable for introduction into a cardiovascular system to improve the treatment of blockage within the cardiovascular system or its surrounding tissues. The ultrasonic echo detection system is comprised of an ultrasonic balloon catheter embedded with ultrasound transducers. The ultrasound transducer is utilized for emitting ultrasound continuously and for receiving echo signals from calcified blood vessels. A control system additionally is composed of a signal receiving unit electrically connected to the ultrasound transducers for receiving calcified echo signals, and a digital-to-analog conversion circuit for receiving the echo signal from calcified blood vessels and generating characteristic signal of calcification. A T/R switch circuit is coupled to both the signal receiving unit and the digital-to-analog conversion circuit, and a processing unit electrically connected to the digital-to-analog conversion circuit to analyze and calculate the characteristic signal of calcification, thereby generating a control signal which is used to enhance or reduce the ultrasound output energy. The amplifier circuit, which is electrically connected to the processing unit, is used to amplify the resonance signal based on the control signal, thereby causing the ultrasound transducers to emit ultrasound.
