    • A shaft-seal device for high-temperature fluid including a seal case (2) formed as a metallic cylindrical structure of a single unit and comprised of a main body portion (2a, 2b, 2c), first and second holding portions (2d, 2e), first and second partition portions (2f, 2h), a channel formation portion (2g) forming a minute annular channel (27) with the outer circumference surface of a rotary shaft (1), and an o-ring holding portion (2i). The seal case is installed in an apparatus housing (8) with first and second o-rings (2m, 2n) in between. The intra-seal case region (A1), in which sealing rings (31, 32, 41, 42, 51, 52) of mechanical seals (3, 4, 5) are provided, and the high-temperature fluid region, which is an intra-apparatus housing region (A), are partitioned by a cooling chamber (28) into and from which coolant (82) is supplied and discharged via feed/discharge coolant paths (80, 81).

    • A segmentation method and system for medical images of a structure, including at least one substructure are described herein. Examples of such structure and substructures are a vertebra and its spinal canal or a sacrum with its two foramens. The method consists of first providing a plurality of digital images representing consecutive slices of the structure. The set of images is then divided into groups for which initial substructures center position are estimated. Using this information, the pixels corresponding to each substructure and common to all the images in the group are determined. Iterations are performed between these two last steps until the best candidates are obtained. The method consists then in estimating the substructures center position in each image of the group. After the substructures have been identified in each image, the images are then processed to remove noise in the substructures, in the rest of the structure and outside the structure.
    • 本文描述了包括至少一个子结构的结构的医学图像的分割方法和系统。 这种结构和子结构的实例是椎骨及其椎管或具有其两个孔的骶骨。 该方法包括首先提供表示结构的连续切片的多个数字图像。 然后将该组图像划分成对其初始子结构中心位置进行估计的组。 使用该信息,确定与每个子结构相对应的像素并且对于该组中的所有图像共同的像素。 在这两个最后的步骤之间进行迭代,直到获得最佳候选者。 该方法包括估计组中每个图像中的子结构中心位置。 在每个图像中已经识别到子结构之后,然后处理图像以去除子结构中的噪声,在结构的其余部分和结构外部。
