Transformation of a set of slices rotated on a common axis to a set of Z-slices: application to three-dimensional visualization of the in vivo human lens.

A technique that transforms a set of images acquired as a rotating frame about an axis (Z axis) into a set of images along the Z axis in presented. This technique is applied to the three-dimensional visualization of the in vivo human lens. A Scheimpfling slit camera acquired 60 optical images through the in vivo human lens. Between each image acquisition the plane containing the slit beam of light was sequentially rotated. This set of 60 images was transformed into a new stack of images on the Z axis. The transformed stack of Z images was visualized with volume rendering software.
