This document discusses the production of x-rays for diagnostic radiology. It describes how bremsstrahlung and characteristic x-rays are produced when electrons interact with matter. It also discusses how factors like tube voltage, current, filtration, target material and waveform affect the quality and quantity of the x-ray beam. Beam filtration is important as it can shift the beam spectrum to higher energies, reducing patient dose without compromising image quality. Scattered radiation decreases image quality and increases dose, so techniques like anti-scatter grids are used.
