A computerised technique for morphometry and 3D reconstruction of embryological structures.

In the last decade we have witnessed the development of software technology capable of image analysis and morphometry [1, 8-12]. Although these methods are sometimes difficult to master in a practical sense, they are tremendously efficient and precise when applied to the study and measurement of developing biological structures, particularly in the field of embryology. In this study we describe the application on human embryos of an image analyzing system that enables one to perform quantitative analyses of the morphology and size of developing organs and structures as well as their ultimate three-dimensional reconstruction (3DR).
