Vizualizace velkých biologických tkáňových vzorků s použitím laserové konfokální mikroskopie
Čapek, Martin ; Kubínová, Lucie ; Hána, K. ; Smrčka, P.
In biology there is often necessary to visualize a biological specimen which size is greater when compared with the field of view of a used optical acquisition instrument. The visualization of such the specimen can be achieved by volume reconstruction. We study biological specimens by using a confocal laser scanning microscope which is able to capture a digital volume representation of the specimen. We investigate great specimens containing, for example, a human tooth pulp, an epithelial layer and a vascular bed of chick embryonic gut or chick embryonic kidneys
Analýza endoplazmatického retikula konfokální mikroskopií
Janáček, Jiří ; Radochová, Barbora ; Demjénová, E. ; Schwarzerová, K. ; Tomori, Z. ; Karen, Petr ; Kubínová, Lucie
Image analysis techniques for preprocessing, segmentation and estimation of geometrical characteristics of fiber-like structures from images captured by a confocal microscope are presented. Methods are demonstrated on the study of endoplasmic reticulum of tobacco cells
Účinná kompenzace útlumu jasu a kontrastu s hloubkou v konfokální mikroskopii
Čapek, Martin ; Kubínová, Lucie
Images captured by a confocal laser scanning microscope from deep layers of the specimen are often darker than images from the top most layers due to absorption and scattering of both excitation and fluorescent light. These effects cause problems in subsequent analysis of biological objects. Therefore, methods for compensation of the light attenuation with depth must be used
Obnovení jasu a kontrastu datových souborů získaných konfokálním mikroskopem
Čapek, Martin ; Kubínová, Lucie ; Hána, K. ; Smrčka, P.
Images captured by a confocal microscope are degraded by light attenuation with depth. We developed a histogram warping based method to eliminate this problem
