TRANSFORMATION OF A SET OF SLICES ROTATED ON A COMMON AXIS TO A SET OF Z-SLICES - APPLICATION TO 3-DIMENSIONAL VISUALIZATION OF THE IN-VIVOHUMAN LENS

A technique that transforms a set of images acquired as a rotating fra me about an axis (Z axis) into a set of images along the Z axis is pre sented. This technique is applied to the three-dimensional visualizati on of the in vivo human lens. A Scheimpflug slit camera acquired 60 op tical images through the in vivo human lens. Between each image acquis ition the plane containing the slit beam of light was sequentially rot ated. 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. (C) 1997 Elsevier Science Ltd.
