Study Notes
Fluoroscopy
- Dynamic, real-time imaging technique used in operating theatres to guide surgeons in placement
- Provides continuous image of motion, with frame rate over 30 frames per second
- Capable of capturing static images (spot film) in 2D
Varieties of Fluoroscopy
- Mobile source and fixed set-ups, including interventional suite areas
- Image receptor can be placed over or under the table
History of Fluoroscopy
- Created by Thomas Edison, but he stopped research after his assistant died from metastatic skin cancer due to radiation exposure
Benefits of Fluoroscopy
- Provides images of continuous nature, enabling real-time dynamic imaging and screening
Physical Principles of Operation
- X-ray source: same as general x-ray tube
- Image receptor: different from x-ray, can be flat-panel detector or image intensifier tube
- Image intensifier tube:
- Complex electronic device
- Converts image to higher intensity and brightness
- Creates light of higher intensity and brightness
- Encased in glass with a scintillation layer
Exposure Parameters
- kVp (x-ray energy) depends on body region
- Tube current is typically low
