Study Notes
Introduction to X-rays
- Discussion on imaging technology, focusing on macro and micro imaging techniques
- Importance of X-rays in understanding internal issues
Historical Context
- James Garfield's assassination: Difficulty locating the bullet due to lack of imaging technology
- Alexander Graham Bell's metal detector: Failed due to interference from bed springs
Photographic Revolution
- Advances in photography were vital for X-ray development
- High-quality imaging was necessary for effective X-ray applications
Discovery of X-rays
- Wilhelm Röntgen discovered X-rays accidentally using cathode ray tubes
- First X-ray image: Röntgen's wife's hand, showing bones and a wedding ring
Applications of X-rays
- Early use in medical diagnostics
- Treatment for skin conditions like psoriasis
- Identifying foreign objects inside the body
- Radiation side effects initially unknown
How X-rays Work
- Short wavelengths and high energy
- Penetrate soft tissue but absorbed by dense materials like bones
- Can damage DNA at atomic level due to energy transfer
X-ray Technology
- Modern X-ray tubes provide focused radiation for precision
- Enabled the development of dynamic imaging and 3D structures (e.g., CT scans)
Advanced Applications
- X-ray Microscopy: Cellular-level imaging analysis
- X-ray Crystallography: Determines molecular structures (e.g., proteins, DNA)
- Stereophotogrammetry: Combines X-rays with markers for surgical precision, especially in joint replacements
