PURPOSE:To enable the synthesizing and superimposing of images of the same human body at an arbitrary position as obtained from different types of devices by sealing up a marker serving as position information source into a cavity or a fine catheter-shaped tube of material. CONSTITUTION:In a CT image, tubes 6, 7 and 8 are recognized as those 13, 14 and 15 by a means 25 for perceiving tubes in a body part sliced and among position markers comprising a second material tapered in the tubes, the position markers 16, 17 and 18 are perceived by a means 26 for perceiving position markers existing in inner diameter of the tubes. The positions of the above markers are detected from (n) slice images by a means 27 which calculates a relative degree of inclination and relative position from (n) pieces of information to calculate a relative variation. This enables obtaining positional information directly from images such as CT and MRI images and inclination information indirectly. |
