IMAGO: a complete system for acquisition, processing, two/three-dimensional and temporal display of microscopic bio-images

Abstract

This work describes IMAGO, an integrated bio-imaging system developed in our laboratory. The whole system consists of a personal computer, a commercially available frame grabber directly plugged into a personal computer, video input/output modules, specific hardware for z-axis movement and light shuttering, and a software package. IMAGO is user-friendly, menu driven and enables one to perform image acquisition with different methods: optical sectioning, flashing epifluorescence, transmitted and phase contrast microscopy. It makes various functions possible, including: image transfer, gray scale processing, conventional and advanced filtering, logical operations, look-up table management, three-dimensional (3D) editing, 3D representation and auto-correlation techniques. More than 100 image processing functions have been implemented and can be easily managed through IMAGO. Examples are given in the area of biophysical research, like 3D representation of nuclei and of electron microscopic images, in situ microscopy of living cells. IMAGO processes information in an x, y, z, t space.
