3D Images 10 Times Faster

In x-ray phase contrast imaging (XPCI), pictures are created by tracking changes in both the x rays’ phase and absorption after they have passed through the object of interest. Now researchers report a new image reconstruction algorithm that halves the number of x-ray shots required to produce the image. Implementing the algorithm also eliminates the need to reposition optical elements between exposures, so the total acquisition time can be cut to a tenth of the usual. Faster acquisition may benefit biological studies that often have a limited time window.
