Study Notes
Radiographic Imaging
- The invisible change induced in the silver halide crystal is known as latent image formation.
- The immediate result after exposure to image-forming x-rays is the formation of silver atoms, which eventually become visible as the image develops.
Energy Deposition Pattern
- The energy deposit pattern representative of the anatomical part being radiographed is called the subject contrast.
Radiographic Intensifying Screen-Film
- The energy in the emulsion of the radiographic intensifying screen-film is primarily deposited through absorption of x-ray photons, which excites the phosphor atoms, leading to light emission.
X-ray Tube Failure
- Causes of x-ray tube failure include anode heat overload, filament failure, and power supply faults.
- The potential consequences of anode cracking or pitting in an x-ray tube are reduced x-ray output, increased risk of tube failure, and decreased image quality.
- X-ray tube failure can occur due to mechanical damage, such as physical shock, vibration, or dropping the tube.
