摘要： Disclosed herein is a method for quantifying a pigmented lesion using Optical Coherence Tomography (OCT). The method includes (a) irradiating light and receiving an interference signal produced by reflection of the light from first and second boundary layers of a pigmented lesion; and (b) calculating size information of the pigmented lesion using phase information of the interference signal. According to embodiments of the present invention, there is an advantage of allowing calculation of size information of a pigmented lesion using OCT, by increasing a measurement range in the axial direction to which beams are irradiated.

摘要： 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.

摘要： The present invention relates to a three-dimensional oral cavity scan device for a digital impression that obtains a three-dimensional image by processing a two-dimensional image acquired by photographing a three-dimensional subject in an oral cavity. The device includes: a pattern mask converting parallel light incident thereto into structured light; a piezoelectric plate where a mechanical vibration is generated on a surface thereof by an AC voltage applied thereto; and a power supply unit applying the AC voltage to the piezoelectric plate, wherein the piezoelectric plate moves the pattern mask in a longitudinal direction of the piezoelectric plate by using the mechanical vibration. The device can reduce noise and vibration by moving the pattern mask with an electrical method. In addition, the device can accurately measure depth of teeth by electrically controlling a focal length of structured light projected on the teeth.
