The present invention relates to a photoacoustic / ultrasonic fusion catheter and a system and method for acquiring an integrated image using the same, and more particularly, to a photoacoustic / ultrasound fusion catheter having a body connected to a rotary stage. And a head coupled to the body to obtain a photoacoustic / ultrasound signal, the head including: an ultrasonic transducer capable of receiving and transmitting photoacoustic / ultrasound signals An optical fiber passing through the head and the body and transmitting the laser in the direction of the ultrasonic transducer A prism attached to a distal end of the optical fiber in the direction of the ultrasonic transducer to radiate a laser transmitted through the optical fiber to a target tissue in a radial manner And a wire which passes through the head and the body and is connected to the ultrasonic transducer to transmit a photoacoustic signal obtained through the ultrasonic transducer to an image processing unit.According to the photoacoustic / ultrasound fusion catheter proposed in the present invention and the system and method for acquiring an integrated image using the same, it is possible to maintain the various merits of the existing single ultrasound image by fusing the ultrasound image and the photoacoustic imaging technique, Combining new advantages such as acquisition of physiological information, excellent contrast ratio and spatial resolution of acoustic images, the lesion can be diagnosed more accurately than existing methods.Further, according to the present invention, by using the optical fiber and the micro prism, the catheter size is reduced by the dense catheter internal structure and spread radially when the light is emitted from the optical fiber, By adapting to the limiting pulse rate of a deep, tunable laser, ultra-high-speed imaging is possible and an epoch-making effect compared to previous catheters can be obtained.본 발명은 광음향/초음파 융합 카테터와 이를 이용한 통합 영상 획득 시스템 및 방법에 관한 것으로서, 보다 구체적
