Towards 100 nm resolution X-Ray tomography

Using a nano-focus x-ray source we have been able to visualize structures down to 150 nm in x-ray projection images. Because of their unlimited depth of focus, these sources don´t restrict the specimen size in case of 3D tomographic imaging. Simulation studies have shown that optimization of the detector response curve and switching from a reflective x-ray target to a transmission target might allow us to reach sub-100 nm resolutions.
