Figure 8
Background-subtracted ultra-low-angle diffraction patterns of a cardiac papillary muscle in the diastole state recorded with 5 ms X-ray exposure. The well defined reflections correspond to the axial repeat of the sarcomeres of length ∼2.2 µm. Patterns (a) and (b) were recorded by the FReLoN and Eiger2 4M detectors, respectively. The fibre axis is along the vertical and the specimen was provided by courtesy of M. Linari et al. (University of Florence, Italy). |
