📚 Understanding Factors

kVp (Kilovoltage Peak)

Controls beam penetration and contrast. Higher kVp reduces dose but lowers contrast (more gray shades).

mAs (Milliampere-seconds)

Controls x-ray quantity and image density. Directly proportional to patient dose. Keep as low as possible (ALARA).

Grid Usage

Absorbs scatter radiation to improve image contrast. Requires higher mAs (dose) to compensate for absorption.

SID (Distance)

Inverse Square Law: Increasing distance significantly reduces intensity, requiring more mAs to maintain exposure.
