The use of a fast-readout CCD x-ray detector in a scanning transmission x-ray microscope (STXM) allows a range of simultaneous imaging modes to be realised. The CCD records the full 2-D distribution of x-rays transmitted by the sample for every pixel in the raster scan that generates the STXM image, potentially generating large volumes of data. The data in each CCD frame can then be processed in a variety of ways to produce useful image signals, including both absorption and phase contrast. Since the detector effectively records a convergent-beam micro-diffraction pattern for every position in the STXM raster other processing algorithms can be used to provide additional information to the user.
