a bar phantom of thickness 0.5 cm is uniformly irradiated by monoenergetic x-ray photons, and a detector is placed behind the phantom to detect the x-ray photons. the bars of the phantom are made from a material that has an hvl of 0.1 cm. in the space between the bars, x-ray photons pass without attenuation. assuming the intensity of the image is proportional to the x-ray photons that hit the screen in a unit area, what is the relationship of the intensity in the areas of the final image that correspond to the bars vs the space between them? which areas will be brighter, and why? (please note the wording of the question for that!)
