3E.3.3 I.I. Input Dose Calibration
This procedure sets the actual operating input dose to the I.I. Please note the following:
•
Ensure that the collimator is adjusted to only expose the I.I. input.
•
The central ray from the X-ray tube must coincide with the center of the I.I.
•
The required I.I. input dose must be known before proceeding. Typical values (for reference only) are:
⇒
6 inch (15 cm) I.I. = 8.1 mR/min.
⇒
9 inch (23 cm) I.I. = 3.6 mR/min.
⇒
12 inch (30 cm) I.I = 2.0 mR/min
