    • The present invention provides an osteoporosis diagnosis aiding apparatus that utilizes a panoramic radiograph. A digitalized image of the panoramic radiograph enters a personal computer (S210). The cortical bone at the lower edge of the mandibular molar in the panoramic radiograph is specified with a mouse to make that part a target of examination (S220). This extracted image is subjected to the following image processing. (1) Subject the image to median filtering so as to reduce noises throughout that image. (2) Find a skeleton constituted by micro-structural elements (S230). (3) Extract only components parallel to the tilt of the lower edge of the mandible (S240). (4) Binarize the image using Otsu's linear discrimination method, for example (S250). The binarized lines are then classified into three groups according to size, and can be determined as a risk of osteoporosis in a case where there is more than just a single line classified in the largest line group aside from the smallest line group.
    • 本发明提供一种利用全景X线片的骨质疏松症诊断辅助装置。 全景X光片的数字化图像进入个人计算机(S210)。 在全景X光片下的下颌磨牙下缘的皮质骨用鼠标指定使该部分成为检查目标(S220)。 对该提取图像进行以下图像处理。 (1)对图像进行中值滤波,以减少整个图像的噪声。 (2)找到由微观结构元素构成的骨架(S230)。 (3)仅提取与下颌骨下缘倾斜平行的部件(S240)。 (4)使用Otsu的线性判别方法对图像进行二值化,例如(S250)。 然后根据大小将二值化线分为三组,并且在除了最小线组之外的最多线组中不仅仅是分为单线的情况下,可以确定为骨质疏松症的风险。

    • A plasma-assisted deposition system for carrying out a plasma-assisted deposition method has a processing vessel defining a vacuum chamber and having an open upper end, a dielectric member covering the open upper end of the processing vessel, and a flat antenna member placed on the upper surface of the dielectric member. A coaxial waveguide has one end connected to the upper surface of the flat antenna member and the other end connected to a microwave generator. The flat antenna member is provided with many slots of a length corresponding to half the wavelength of a microwave arranged on concentric circles. For example, a circularly polarized microwave is radiated from the slots into a processing space to produce a source gas plasma. Electron temperature in the plasma in terms of mean square velocity is 3 eV or below and the electron density in the plasma is 5×1011 electrons per cubic centimeter or above. The plasma is used for depositing a fluorine-containing carbon film. Preferably, the process pressure is 19.95 Pa or below. Under such process conditions for depositing a fluorine-containing carbon film by using the plasma, the source gas, such as C5F8 gas, is decomposed properly to form a structure of long CF chains. A interlayer insulation film thus formed has a small relative dielectric constant and permits only a low leakage current.
