Technical details

ID17 is dedicated to biomedical imaging, radiation biology and radiation therapy; experiments can run in-vitro or in-vivo in two endstations. The first endstation (MRT) uses filtered white beam (40 - 600 keV) for microbeam, minibeam and pencilbeam radiation therapy and image-guided brain microsurgery. The beam can be either spatially homogeneous or spatially fractionated (using a multi-slit collimator). The second endstation (imaging) uses monochromatic X-rays for radiography, microtomography, radiation biology and radiation therapy. Up to 4 monochromators are available, each having its own range of energies and beam sizes. The beamline and annexed laboratories deal with scales from cell samples up to human patients. Imaging modes include absorption, time-resolved, K-edge substraction, phase contrast: propagation based, analyzer based, coded aperture. Both radiography and tomography can be done with time resolution. APPLICATIONS: Examples of applications include preclinical radiation therapy, radiation biology studies using monochromatic beams, preclinical brain microsurgery, in-vitro phase contrast imaging (mammography, cartilage studies, etc.), functional imaging: bronchography (large volume or time resolved), and paleontology studies using 3D high-resolution imaging of samples requiring a wide beam (skulls, bones, etc.).
