The radiographs of the tumor vessel cast were measured at TOMCAT beamline (SLS at Paul Scherrer Institute, Villigen, Switzerland): (a) global radiograph with a pixel size of 5.92 µm; the dashed-line rectangle illustrates the region measured for local tomography with a pixel size of 0.74 µm; the full-line rectangle denotes the region of interest shown in the other images: (b) radiograph of local tomography using a pixel size of 0.74 µm, (c) cropped area from global radiograph, (d) re-sampled image from local radiograph; (e) difference image between the global projections (Ig) and re-sampled local projection (Il) to reveal their intensity differences. The 100 µm grids are incorporated as guidelines.  [article HTML]
