Abstract
In order to elucidate the process of morphological formation in the development of human embryos, it is useful to browse their three-dimensional (3D) images. Currently, we are trying to acquire sets of 2D images from a large number of serially sectioned human embryo specimens and reconstruct 3D images from the series of images. Since the specimens have been obtained over a period of time, the 3D reconstruction has to be carried out retrospectively. Problems of image acquisition for retrospective 3D reconstruction include a large amount of manual operation, damage to some sections and variations of orientation. The goal of our research is the efficient acquisition of 2D images. We propose semi-automated methods to acquire images, with the elimination of damaged sections and rearrangement of the series of specimens. From experiments, we have evaluated the effectiveness of our proposed methods.
