For such imaging techniques, the method can therefore significantly improve image quality, or maintain image quality with further reduced exposure time per image.

Here we apply hyperspectral bright field imaging to collect computed tomographic images with excellent energy resolution (800 eV), applying it for the first time to map the distribution of stain in a fixed biological sample through its characteristic K-edge.
