How are the QUALITY of image determined? | Density, Contrast, Recorded Detail, Disortion |
Density | Overall darkening of xray |
Contrast | definition of density-kvp |
Recorded detail | sharpness, resolution, definition |
Distortion | magnification and shape |
Prime factors | mAs, kVp, Distance |
mAs controls | exposure, quantity and output. mAs controls density |
kVp controls | quality, speed of electrons, energy of xray beam, and penetrability. |
Distance | 72inch, 40inchs, SID, OID |
Magnification is controlled by | OID & SID |
