One important application for three-dimensional microscopy is the determination of the volumes of biological cells. In this paper we investigate the application of three-dimensional deconvolution techniques to the problem of cell volume determination. The theoretical discussion is based on a Fourier sampling condition for reliable image reconstruction and it is shown, using this condition and simulated images, that the cell volume determination is reliable only for cells with a shape and orientation such that their length along the optic axis is much greater than their width.

The intention of this review is to introduce to microscopists some of the fundamental limits as well as the advances made in digital optical microscopy techniques, also to show their potentialities in the field of molecular cell biology. Several items within the wide field of this subject will be discussed, such as geometric and photometric features, photophysics, statistics of photon flux and detection, spatial and intensity characteristics of digital images, their manipulation and display, fluorescent probes, and measuring techniques.
