A. Phase Contrast Imaging
The information carried by the phase of X-Ray wavefield,
or phase effects, may be converted into image contrast,
enhancing detail visibility [1], especially if compared to the
poor contrast given by media with small X-Ray absorption
differences. The effect of the phase contrast may be noticed in
Fig. 1 (at the borders of plastic and insect regions). The
images of interest were obtained at the Synchrotron Radiation
for MEdical Physics (SYRMEP) beam line at the Elettra
Synchrotron Laboratory (Trieste, Italy) [2].
The image of interest is the slice no. 183, related to the
sample of the insect Rhodnius Prolixus [3] labeled as C4B,
part of a group of control, object of current biological
research. The image of interest is depicted in Fig. 1. The only
image processing operation performed was the normalization
of the image.
