• Origin:Discovered by Wilhelm Röntgen in 1895, radiography marked the beginning of medical imaging.

• Evolution: It has advanced from film plates to digital systems, improving image quality and reducing radiation exposure.
   

Physical Principles
 

• X-ray Generation:They are produced by bombarding a metallic target with high-energy electrons in an X-ray tube.

• Interaction with Tissues:X-rays are absorbed or attenuated by tissues to different degrees, depending on their density and composition.
   

Equipment and Technology
 

• X-ray tube: The main component that generates X-rays.

• Image Stop System:Includes both traditional film and digital detectors.

• Radiological Protection: Leads and barriers to protect both patient and operator from unnecessary radiation.
   

Techniques and Procedures
 

• Patient Positioning:Essential to obtain the proper view of the area of interest.

• Parameter Selection: Adjusting factors such as exposure time, current and voltage to optimize image quality and minimize radiation dose.
   

Clinical Applications
 

• Diagnosis of Fractures and Bone Injuries:Essential in orthopedics and traumatology.

• Detection of Pulmonary and Thoracic Diseases: Such as pneumonia, pleural effusions and heart diseases.

• Evaluation of Systems such as the Digestive: Detecting obstructions, perforations or gastrointestinal diseases.
   

Recent Advances and Developments
 

• Digital Radiography:Improves image quality and allows manipulations such as brightness and contrast adjustment.

• Radiation Dose Reduction:Technological advances allow high-quality images to be obtained with less exposure to radiation.
   

Challenges and Considerations 
 

• Accurate Interpretation:Requires experience and detailed knowledge of anatomy and pathology.

• Radiation Management:Continue to improve radiation protection and education about radiation risks.
