Comparison of Rhenium and Iodine as Contrast Agents in X-Ray Imaging

Figure 3

Geometry of Monte Carlo simulation. The schematic shows the X-ray beam (red), the Solid Water® phantom (blue), and the detector (brown). A FOV of 20 cm at the surface of the phantom was chosen. All the simulations were conducted assuming a total of 8.5 × 10⁵ photons in the transmitted X-ray beam.
