The present invention relates to an integrated catheter device for cardiovascular diagnosis and an image processing system using the same. According to an specific example of the invention, a cardiovascular image having a number of analytical aspects is obtained by acquiring an image in a cardiovascular region by one catheter using ultrasound, photoacoustic light, and near-infrared light, thereby enabling diagnosis of fibrosis of a blood vessel, atherosclerotic plaque, rupture prediction to be accurately performed.Since the catheter device is provided with the DCF for guiding near-infrared light having a predetermined wavelength in a core portion and guiding photoacoustic light and ultrasonic wave used in a clad portion, it is possible to guide light having different wave-lengths to the sample through the same path simultaneously. Accordingly, it is advantageously possible to reduce the radius of the catheter device capable of acquiring the cardiovascular image having a number of analytical aspects, and to acquire ultrasound, acoustic wave and near-infrared light at the same time.
