Abstract: The present invention relates to a method for extracting collagen from a liposuction effluent, wherein collagen is extracted by treating a collagen-containing liposuction effluent in the presence of a supercritical fluid. According to the present invention, conventionally discarded collagen in a liposuction effluent can be extracted at high purity, and the extracted high purity collagen can be widely used in medical, pharmaceutical, and cosmetic products.

Abstract: The present invention relates to a three-dimensional scanning device and method for scanning the shape of a subject by means of a three-dimensional scanner while rotating the subject and, more specifically, to a three-dimensional scanning device and method wherein scan data of a subject, acquired at arbitrary rotation angles of a turntable, can be automatically registered without user intervention and without a need to perform calibration according to the position of a three-dimensional scanner relative to the turntable.

Abstract: The present invention relates to a three-dimensional intraoral scanner and an intraoral scanning method using same, the scanner being capable of reducing a matching error generated during a three-dimensional model data generation process for all the teeth in an oral cavity, and the three-dimensional intraoral scanner and the intraoral scanning method using same, according to one embodiment of the present invention, generate three-dimensional model data for all the teeth in an oral cavity by using a large-area scan image, thereby enabling the minimization of cumulative errors generated when the three-dimensional scan data is matched, and match, with the three-dimensional model data, three-dimensional scan data generated by using a narrow-area two-dimensional scan image, thereby enabling improved precision of the three-dimensional model data.

Abstract: In a desktop three-dimensional scanner for dental use of the related art, a two-axis rotation motion unit, on which a target object can be placed and rotated in order to image the entire shape of the target object, is coupled to the scanner, and thus, when a subject is placed on the imaging stage and is rotated along the horizontal axis of rotation of the stage, the subject is dropped from the stage by gravity after being inclined, and accordingly, additional fixing means or a receiving jig should be placed on the stage together with the subject to prevent same. In such a case, inconvenience is caused because the target objects to be scanned have various shapes and the fixing means or receiving jigs should fit the shapes thereof.
