Adding Dose Limit Dose Action Points<br />

Dose Limit dose action points let you make a recurring alert for a dose related<br />

task. For example, you must change the field shape to avoid critical structures<br />

such as the spinal cord. In this exercise, you will add a Dose Limit dose action<br />

point.<br />

For Dose Action Points to operate correctly, you must set up<br />

dosimetry for the applicable dose tracking site. To do so,<br />

add the dose site coefficients that calculate the dose<br />

contributions from each applicable prescription site. Refer<br />

to Lesson 6 in Module II of this guide.<br />

1. In the <strong>Radiation</strong> Prescriptions dialog box, double-click the Lung Boost prescription,<br />

then click .<br />

Opens the Dose Limits window, shown in Figure 38.<br />
