3. Brief History of X-rays Discovered by Wilhelm Conrad Roentgen in 8 November 1895. Roentgen observed X-rays while experimenting with cathode rays in a vacuum tube. Received the first Nobel Prize in Physics in 1901 for his discovery. X-rays revolutionized medicine by providing a non-invasive method for imaging the internal structures of the body.

4. X-ray Production Mechanism X-rays are produced when high-speed electrons strike a target material. The process involves: Electron acceleration : Electrons are accelerated from the cathode to the anode within an X-ray tube. Target interaction: Electrons collide with the target material (usually tungsten) on the anode. X-ray emission: Energy from the collision is emitted as X-rays.

6. Types of X-ray Production Characteristics of X-ray Production: 1. X-rays are a form of electromagnetic radiation with high energy and short wavelengths. 2. They are produced when high-energy electrons, accelerated by a voltage, collide with a target material. 3. X-rays can penetrate through soft tissues but are absorbed by denser materials like bone and metal. 4. They are used in various fields such as medicine, industry, and research for imaging and analysis.

7. Bremsstrahlung X-ray Production: 1. Bremsstrahlung, German for "braking radiation," occurs when fast-moving electrons are decelerated by the electric field of atomic nuclei. 2. During this process, kinetic energy is converted into electromagnetic radiation, producing a continuous spectrum of X-rays. 3. The energy of the emitted X-rays depends on the initial kinetic energy of the electrons and the strength of the electric field. 4. Bremsstrahlung X-rays are utilized in medical imaging, industrial radiography, and security scanning.

8. Components of an X-ray Tube An X-ray tube consists of: Cathode: Emits electrons through thermionic emission. Anode: Target material where X-rays are generated. Glass or metal envelope: Encloses the cathode-anode assembly in a vacuum. Cooling system: Prevents overheating during operation. Focusing cup: Focuses electron stream towards the anode target.

9. Types of X-ray Tubes There are two primary types of X-ray tubes: Diagnostic X-ray tubes: Used in medical imaging for producing diagnostic images of the body. Industrial X-ray tubes : Employed in non-destructive testing, quality control, and security screening.

10. Medical Applications of X-ray Tubes X-ray tubes play a crucial role in various medical imaging modalities, including: Radiography: Capturing still images of the body's internal structures. Fluoroscopy: Real-time imaging for procedures like angiography and gastrointestinal studies. Computed Tomography (CT): Producing detailed cross-sectional images of the body. Mammography: Screening and diagnosing breast cancer. Interventional Radiology: Guiding minimally invasive procedures.
