3. Type the number of the treatment field in the first Field text box.
4. Type the name of the treatment field in the second Field text box.
5. Click adjacent to the Machine field, then double-click the linear accelerator used to
treat the patient with the field.
6. Click adjacent to the Tolerance field, then select the tolerance table for the anatomical
area to treat.
This defines the degree of tolerance within which the treatment unit parameters must
remain when setting up the patient.
7. Type the dose in Dose field.
Dosimetry lets you calculate dose site coefficients and define the dose
contributions from each applicable prescription site.
8. Click adjacent to the Type field, then select the type of beam.
9. Click adjacent to the Modality field, then select the method of treatment.
10. In the Beam Configuration dialog box, select the Mv in the Energy column, select the
dose rate in the Doserate column, then click OK.
The energy and dose rate options that appear are defined in the machine characterization
of the selected linear accelerator. If an energy level or doserate was not defined in the
machine characterization, it does not appear in the Beam Configuration dialog box.
11. In the Treatment Field Definition dialog box, type the monitor units in the MU field.
The Wedge MU field is only significant for sites with Elekta or GE
linear accelerators. If you have a Varian or Siemens linear
accelerator, never use the Wedge MU field.
12. Type the treatment delivery time in the Time field.
Manually Creating Accessory Information
You can specify parameters for accessories such as wedges, compensators, and blocks.
If you choose electrons for the treatment modality, the Applicator
field appears instead of the Wedge field. The drop-down list shows
cones for the selected machine.

the Wedge field, then select the wedge to be used in treatment.
