    • 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。

    • There are disclosed a vaporizer wherein at least a portion of a CVD material feed portion in contact with a CVD material is constituted of a corrosion resistant synthetic resin; and an apparatus for vaporizing and supplying which comprises a cooler and the vaporizer wherein the inside of the CVD material feed portion of the vaporizer and the surface on the side of the vaporization chamber of the CVD material feed portion are constituted of a corrosion resistant synthetic resin; the feed portion in contact with the outside of the vaporizer is constituted of a metal; and the CVD material feed portion which is constituted of a metal and which undergoes heat transfer from the heating means upon heating the vaporization chamber can be cooled with a cooler. The vaporizer and apparatus, when used for supplying a gaseous CVD-material to CVD equipment for producing semiconductors, enables the CVD material to be efficiently vaporized and supplied at desirable concentration and flow rate without causing deposit or adhesion of the CVD material at a CVD material feed port even if a solid CVD-material is used.
