    • According to one embodiment, a CT scanning tabletop includes a tabletop body and an aid. The tabletop body has a placement surface where a subject is to be placed, and is formed in a manner that an X-ray transmission loss by one end portion in a longitudinal direction thereof is smaller than an X-ray transmission loss by a portion of the tabletop body other than the one end portion. The aid is provided on the one end portion in a manner that the aid is attachable and detachable by moving in advancing and retreating directions toward and away from the placement surface, the aid is configured to hold a part of the subject.
    • 根据一个实施例,CT扫描台面包括台面主体和辅助部件。 桌面本体具有放置对象的放置面,并且以使得其长度方向上的一个端部的X射线透射损失小于X射线透射损失的方式形成 桌面体以外的一个端部。 辅助设置在一个端部上,其方式是借助于朝向和远离放置表面的前进和后退方向的移动而可以附接和拆卸该辅助件,该辅助件构造成保持被摄体的一部分。

    • There is provided a contour extraction apparatus and a method thereof by which candidate data of a plurality of subjectively evaluable contour curves can be presented to a user by obtaining an accurate color projection axis and the user can be invited to make selection. An update sector extract section 31 obtains an update sector of a closed contour curve from representative points specified by a user. A color projection axis candidate calculator section 32′ calculates a plurality of color projection axes which maximizes contrast around an edge within the update sector, based on representative points 1 and 2 and an image. A contour curve generator section 33 generates a contour curve candidate list corresponding to the list of the plurality of color projection axis candidates. The contour curve candidate list generated by the contour curve generator section 33 is displayed on a display device. Further, a user is invited to make selection by a candidate list select section 71, and the color projection axis selected by the user is sent to the contour curve generator section 33. The contour curve generator section 33 generates a new contour curve within the update sector from the image, representative points 1 and 2, and the color projection axis. The update sector synthesizer section 34 synthesizes the contour curve of an updated sector with a closed curve thereby to generate a new closed contour curve.
    • 提供了一种轮廓提取装置及其方法,通过该轮廓提取装置及其方法,通过获得准确的颜色投影轴可以向用户呈现多个可主观评估的轮廓曲线的候选数据,并且可以邀请用户进行选择。 更新扇区提取部分31从由用户指定的代表点获取封闭轮廓曲线的更新扇区。 颜色投影轴候选计算部32'基于代表点1,2,以及图像,计算使更新扇区内的边缘的对比度最大化的多个颜色投影轴。 轮廓曲线生成部33生成与多个颜色投影轴候选的列表对应的轮廓线候选列表。 由轮廓曲线生成部33生成的轮廓曲线候选列表显示在显示装置上。 此外,请求用户由候选列表选择部分71进行选择,并且由用户选择的颜色投影轴被发送到轮廓曲线生成部33。轮廓曲线生成部33在更新内生成新的轮廓曲线 图像中的扇区,代表点1和2以及颜色投影轴。 更新扇区合成器部分34将具有闭合曲线的更新扇区的轮廓曲线合成,从而生成新的闭合轮廓曲线。
