3D Data

The quantitative use of electron diffraction intensity data for the determination of crystal structures represents the pioneering achievement in the electron crystallography of organic molecules, an effort largely begun by B. K. Vainshtein and his co-workers. However, despite numerous representative structure analyses yielding results consistent with X-ray determination, this entire effort was viewed with considerable mistrust by many crystallographers. This was no doubt due to the rather high crystallographic R-factors reported for some structures and, more importantly, the failure to convince many skeptics that the measured intensity data were adequate for ab initio structure determinations.We have recently demonstrated the utility of these data sets for structure analyses by direct phase determination based on the probabilistic estimate of three- and four-phase structure invariant sums. Examples include the structure of diketopiperazine using Vainshtein's 3D data, a similar 3D analysis of the room temperature structure of thiourea, and a zonal determination of the urea structure, the latter also based on data collected by the Moscow group.

Präoperative Diagnostik

ZusammenfassungEine der kontroversesten Diskussionen in der Netzhautchirurgie wird derzeit über den Stellenwert der intraoperativen optischen Kohärenztomografie (iOCT) geführt. Hintergrund ist der Wunsch, den 2-dimensionalen Fundusblick des Operateurs mit der geschichteten Tiefeninformation der OCT zu kombinieren, um eine Art 4-dimensionale „Augmented Reality“ (3-D plus Veränderung über die Zeit) zu erreichen. Dies soll feine Strukturen, die dem Blick des Operateurs bisher verborgen sind, sichtbar machen. Deshalb erscheint die Netzhautchirurgie prädestiniert für den Einsatz einer iOCT zu sein. Die große Hoffnung liegt darin, dass ein dynamisches Live-3-D-Bild mit Echtzeit-Feedback dem Operateur zusätzliche Informationen liefert und die Sicherheit verbessert. So faszinierend die iOCT-Technologie auf den ersten Blick ist, so enttäuscht sie doch im klinischen Alltag, gerade in der Makulachirurgie. Sie liefert nur selten Informationen, die ohne iOCT nicht erzielbar wären oder durch präoperative Diagnostik nicht in wesentlich besserer Qualität vorlägen. Hoffnungsvoll sind einige Sonderindikationen, die insbesondere die subretinale Chirurgie betreffen.
