Conditions to Meet Previously Mentioned Accuracies
- Handswitch must have been released for 25 seconds after previous exposure.
- 15-minute interval after change completion with keyswitch in ON or CHARGE.
- Main power circuit breaker ON must be allowed before making an exposure
Collimator
- Minimum inherent filtration is 1.5 mm aluminum equivalent to 150 kVp. Additional filtration may be obtained by inserting 1 mm and/or 2 mm aluminum filters.
- Minimum source-to-skin distance is limited to more than 30 cm by the tracks on the bottom of the collimator for mounting the accessory extension cylinder.
- Full 17" x 17" (.43 m x .43 m) radiographic coverage at 40" (1.02 m) source to image distance is provided for tubes with a 15-degree target angle.
- Collimator can be rotated and locked positively at 0°, ±15°, ±30°, ±45°, and ±90° from the front position.
