X-ray deconvolution microscopy.
Recent advances in single-photon-counting detectors are enabling the development of novel approaches to reach micrometer-scale resolution in x-ray imaging. One example of such a technology are the MEDIPIX3RX-based detectors, such as the LAMBDA which can be operated with a small pixel size in combination with real-time on-chip charge-sharing correction. This characteristic results in a close to ...
متن کاملPhotoelectron X-ray Microscopy
The soft-X ray range, between 1-10 nm wavelength, is highly interesting for X-ray microscopy. Taking advantage of it requires, however, to operate a high resolution instrument at a variable wavelength. We describe here an image converter X-ray microscope which is based on secondary pharoemission. This instrument is now developped at the Institut dlOptique (Orsay); it will be installed near ACO ...
متن کاملX-Ray Microscopy
Injuries were made in rabbit corneas 4-48 hours before tritium-labelled thymidine were injected. Only the injured cells picked up the thymidine. Injured lens cells of rats, rabbits and frogs incorporated thymidine within 14-16 hours with increasing numbers up to 32 hours. Cysteine which stops mitosis for four days, was definitely found to protect lens cells from radiation damage, particularly w...
متن کاملImage formation in cellular X-ray microscopy.
Soft X-ray Tomographic (TomoX) microscopy has become a reality in the last years. The resolution range of this technique nicely fits between confocal and electron microscopies and will play a key role in the elucidation of the organization between the molecular and the organelle levels. In fact, it offers the possibility of imaging three-dimensional structures of hydrated biological specimens n...
متن کاملImage Quality Enhancement in X-Ray Microscopy
The goal of this work is to develop digital image processing tools for improving the quality of the images provided by the Göttingen transmission X-ray microscope at BESSY [1, 2]. We first present a method for correcting the inhomogeneous illumination. Then, we present results of image restoration techniques applied to X-ray microscopy images of test objects and of biological specimens containi...
