Adding Measurement Settings<br />
Measurement settings include SSD (Source to Skin Distance), SFD (Source to Film<br />
Distance), and the SAD (Source to Axis Distance). In this exercise, you will add<br />
measurement settings.<br />
1. In the Simulation Field dialog box, type 92.5 in the SSD measurement field.<br />
Specifies the Source to Skin Distance.<br />
2. Type 145 in the SFD measurement field, then press TAB.<br />
Specifies the Source to Film Distance, then moves the insertion point to the SAD<br />
measurement field.<br />
3. Type 100 in the SAD measurement field, then press ALT+G.<br />
Specifies the Source to Axis Distance, then moves the insertion point to the<br />
Gantry field in the Geometric group.
