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
