What is filtration?
Understand the Problem
The question discusses the concept of filtration in radiography, focusing on the elimination of unwanted low energy X-ray photons, the types of filtration, and its effects on patient dose and beam intensity. It aims to provide an overview of the importance and function of filtration in X-ray imaging.
Answer
Filtration separates solids from liquids or gases using a filter medium.
Filtration is the process of separating solid particles from liquids or gases using a filter medium that permits only the fluid to pass through, leaving the solid particles behind.
Answer for screen readers
Filtration is the process of separating solid particles from liquids or gases using a filter medium that permits only the fluid to pass through, leaving the solid particles behind.
More Information
Filtration is commonly used in everyday situations such as brewing coffee or purifying water. The principle is to have a porous material that allows only certain sizes of particles to pass through.
Tips
A common mistake is confusing filtration with other separation techniques like centrifugation or decantation, which also separate substances but through different methods.
