Catheter and system for detecting the ultrasound signal and the photoacoustic signal

The present invention relates to an image acquisition system using the catheter, and this, for detecting ultrasonic / photoacoustic signal. The catheter has a lens optic; An ultrasonic transducer for transmitting and receiving ultrasonic signals; Wires for transmitting and receiving a signal is connected to the ultrasonic transducer; The catheter body disposed such that the lens optic and the through wire therein; The catheter is connected to the head end of the catheter body; And surrounding the surface of the membrane of the catheter head; equipped with a, and the ultrasonic transducer end of the of the lens optic lens is mounted fixed to the catheter head, and the ultrasonic transducer is provided to receive ultrasound signals and photoacoustic signals . The catheter according to the invention is able to provide a concentration of light by using a lens optic and is configured to transmit and receive ultrasound signals obtained photoacoustic signal or to use them to obtain a photoacoustic image of the ultrasound image and the high resolution at the same time .
