Study Notes
High-Voltage Generator
- Provides power to the x-ray tube in three ways: single-phase, three-phase, and high-frequency power.
- mAs determines the number of x-ray photons produced by the x-ray tube.
Operator's Console Controls
- Major controls include: on/off, kVp selection, mA selection, and time (mAs) selection.
- Most consoles utilize computer technology.
kVp and Radiographic Image
- Adequate penetration of the area of interest is required before adjusting mAs for image quality.
- Increasing kVp results in more radiation reaching the image receptor (IR).
- kVp affects both image density and contrast.
- Increasing kVp increases IR exposure and film density, while decreasing kVp decreases IR exposure and film density.
X-ray Imaging System Power Requirements
- Most systems operate on 220 V power.
- Some systems can operate on 110 V or 440 V.
