    The confocal fluorescence microscope is considered as a true volume imager but intrinsic imaging properties of the optical scheme yield a corrupted image that can hamper quantitative analysis of successive image planes. By a post-image collection restoration we obtained an estimate of the true object, utilizing the Point Spread Function (PSF).The PSF was measured and predicted to have a mathematical and physical model of the image-formation process. We used the regularized Iterative Constrained Tykhonov Miller restoration algorithm for solving the inverse problem. In order to compare the effective improvement in the quantitative image information analysis, we measured the volume of reference objects before and after image restoration, using the isotropic fakir stereological method

    Použili jsme dekonvoluci obrazu pro zpřesnění odhadu objemu z konfokálních řezů. Zpřesnění bylo vyhodnoceno porovnáním odhadů objemů referenčních objektů před a po dekonvoluci s využitím fakírské stereologické metody
