Notes Adding Geometric Settings<br />
Geometric settings include gantry angle, collimator angle, field size, and couch<br />
settings. In this exercise, you will add geometric settings.<br />
1. In the Simulation Field dialog box, type 12 in the Field X geometric field.<br />
Specifies the size of the X jaws for the simulation.<br />
2. Type 15 the Field Y geometric field.<br />
Specifies the dimensions of the Y jaws for the simulation. Fields are automatically<br />
symmetrical unless you click the X Jaws Asy and/or the Y Jaws Asy checkboxes.<br />
You can then add individual measurements for each jaw.<br />
3. Type 111.2 in the Couch Vrt geometric field.<br />
Specifies the couch vertical setting.<br />
4. Type 97.1 in the Couch Lat geometric field.<br />
Specifies the couch lateral setting.<br />
5. Type 125 in the Couch Lng geometric field.<br />
Specifies the couch longitudinal setting. Keep the Couch Ang and Couch Ped fields at<br />
their defaults. Replace the parameters above with the correct parameters for your<br />
simulator if necessary, shown in Figure 60.<br />
