In the previous sections, the concepts of X-ray generation and also their interaction behavior with matter has been outlined. In this section, we will now focus on different detection methods used to convert the X-rays that have passed the patient to an actual image. Unlike the old X-ray films, which use X-rays directly to change the chemical properties of the X-ray film material, the modern detection systems first convert the X-rays to light and eventually to electrons.
7.4.1. Image IntensifiersX-ray image intensifiers are vacuum tubes that are used to convert X-rays into visible light, i. e., an image. The schematic principle of this process is shown in . First, the incoming X-ray photons are converted to light photons using a phosphorus material called the input phosphor. The produced light is further converted to electrons by exploiting the photoelectric effect inside a photocathode. These electrons are then...
