Three-dimensional image construction equipment and three-dimensional image construction method

摘要

to construct a three-dimensional image can be easily observed a specific region, arithmetic unit 2 generates a depth image corresponding to the first three-dimensional image to the region of interest (S 11), the region of interest at the inner, setting the first image area on the basis of the depth gradient of depth image (S12). Next, the arithmetic unit 2, the pixel of the first image region, and moves to the back side or the front side only projection line direction moving amount B of the origin of the projection line (S 13), the first image area, after the movement configure the depth image based on the origin of the projection line of the (S 15), in the first image region, set the second image area based on the depth gradient of the depth image based on the origin of the projection line after the movement (S16) , until the end condition is satisfied, the second image area as a first image region (S 18), and repeats the processing of S13. After satisfying the end condition, the operation part 2, based on the origin of the projection line after the movement, it constitutes the second of the three-dimensional image (S19).
