    • The positions where back-projection lines from a plurality of images pass through a predetermined voxel slice of a 3D space are calculated. Letting a predetermined one of the plurality of images be defined as a basic image and the other remaining images as reference images, information about back-projection lines from the basic image is stored in a basic back-projection line information storage part and information about the back-projection lines from the reference images are stored, as information associated with voting, in a voting information storage part. A count is taken of reference back-projection lines which pass through the same passing position of each basic back-projection line, and this count value is used to update the information about the basic back-projection line. After execution of each processing in all voxel slices of the 3D space, the information about the basic back-projection line information is read out of the basic back-projection line information storage part.
    • 计算来自多个图像的背投影线穿过3D空间的预定体素片的位置。 将多个图像中的预定图像定义为基本图像,将其余剩余图像定义为参考图像,将来自基本图像的关于背投影线的信息存储在基本背投影线信息存储部分中,以及关于 来自参考图像的背投影线作为与投票相关联的信息被存储在投票信息存储部分中。 拍摄通过每个基本背投影线的相同通过位置的参考反投影线的计数,并且该计数值用于更新关于基本背投影线的信息。 在3D空间的所有体素片中执行每个处理之后,从基本背投影线信息存储部读出关于基本背投影线信息的信息。

    • An endoscope has a first bending portion, a second bending portion, and a hand-held unit. The first bending portion is the distal portion of an elongated insertion member and has a plurality of joint pieces concatenated so that the joint pieces can rotate freely. The second bending portion is located at the proximal end of the first bending portion, and has a plurality of joint pieces concatenated so that the joint pieces can rotate freely. The hand-held unit is located at the proximal end of the insertion member, and has a control section that is used to bend the first bending portion and second bending portion. In the endoscope, the control section of the hand-held unit has an angling knob that is used to bend the first bending portion, and a second angling lever that is used to bend the second bending portion.
