摘要： The present invention relates to an expandable stent which does not contract in an axial direction during expansion. The expandable stent has an axial direction, a circumferential direction, and a radial direction. Also, the expandable stent has a cylindrical shape before and after the expandable stent is expanded in the radial direction. The expandable stent includes a plurality of rings, a plurality of first flexible links, and a plurality of second flexible links. The rings are arranged in the axial and circumferential directions. The first flexible links may connect together two rings that are adjacent along the circumferential direction in the links, and may be expandable in the circumferential direction. The second flexible links may connect together two rings that are adjacent along the axial direction in the links, and may be expandable in the axial direction. According to the present invention, since the contraction of the expandable stent in the axial direction during the expansion is minimized by the rings, the stent may be accurately disposed at a position such as in a lumen.

摘要： The present invention relates to a non-invasive early diagnostic method and device that allows an early diagnosis of Marssonina blotch disease, which infects apple tree leaves, before the occurrence of lesions to enable early prevention of apple Marssonina blotch disease. The method and device of the present invention comprise the following steps: irradiating a broadband light source on an apple tree leaf undergoing diagnosis by means of optical coherence tomography; detecting interference signals from light reflected from the apple tree leaf undergoing diagnosis and light reflected from a reference arm; signal processing the interference signals, which have been detected through optical coherence tomography by means of a signal processing unit; obtaining digital tomographic image data on the apple tree leaf undergoing diagnosis; analyzing the digital tomographic image by means of a diagnostic unit; and observing the boundary of at least two tissues, wherein the apple tree leaf undergoing diagnosis is considered to be healthy and uninfected with Marssonina blotch disease if the boundary between at least two tissues is clearly defined, and wherein the apple tree leaf undergoing diagnosis is considered to be infected with Marssonina blotch disease if the boundary between at least two tissues is not clearly defined.

摘要： The present invention relates to a noninvasive method and apparatus for screening seeds of high quality, which is capable of noninvasively distinguishing healthy and virus-free seeds from virus-infected seeds using an optical tomography technique. The noninvasive apparatus for screening seeds of high quality can screen seeds of high quality rapidly, simply, and accurately by: noninvasively capturing tomograms of seeds to be diagnosed by means of an optical coherence tomography machine; acquiring tomogram data of the seeds to be diagnosed by signal-processing an optical coherence signal from the captured tomogram; analyzing the acquired tomogram data to compare the analyzed tomogram data with preset reference tomogram data; diagnosing whether the seeds are infected or healthy according to the comparison result; and screening seeds of high quality by distinguishing healthy seeds from infected seeds according to the diagnosis result. Accordingly, the noninvasive method and apparatus for screening seeds of high quality can be utilized in a variety of applications for domestic and foreign seed companies and for plant quarantine inspection.
