Preparing the System and Patient for Image Registration<br />
CAUTION<br />
Make sure that your treatment machine gantry, collimator, SAD,<br />
and all couch sections are properly characterized. Your<br />
ELEKTA/Impac installer typically does this. The Image Registration<br />
process will not work properly if your machine is not properly<br />
characterized. Contact ELEKTA/Impac to assist you with proper<br />
machine characterization.<br />
Configuring Setup Offset Reference<br />
1. Click File | System Utilities | Department Setup…, then click the Clinical (RO) tab<br />
in the Department Setup dialog box.<br />
2. Click adjacent to the Setup Offset Reference field.<br />
Shows the two Setup Offset Reference options, as shown in Figure 35.<br />
Figure 35: Setup Offset Reference Options<br />
These options specify whether to move the isocenter or patient in the direction of setup<br />
correction. The settings are opposite each another. If you move the patient in the inferior<br />
direction, the isocenter moves in the superior direction.<br />
3. Click Isocenter to configure <strong>MOSAIQ</strong> for isocenter movement.<br />
The offset is 5cm in the superior direction for the isocenter setting. Error! Reference<br />
source not found. shows a 5 cm shift.<br />
4. Click Patient to configure <strong>MOSAIQ</strong> for the direction of the patient motion.<br />
The offset would be 5mm in the inferior direction for this setting.<br />
Entering Site Setup for the Prescription<br />
<strong>MOSAIQ</strong> uses the machine coordinates from the machine characterization and the patient<br />
orientation specified in the Site Setup Definition window to provide set-up corrections in<br />
patient coordinates. The ELEKTA/Impac installers or your system administrator<br />
characterizes the machines in <strong>MOSAIQ</strong>, but you must add the patient orientation setting in<br />
the Site Setup Definition window if it was not imported with your treatment plan. Image<br />
Registration also requires a site setup for all prescription sites.<br />
1. Click eChart | Diagnoses and Interventions… to open the Diagnoses and<br />
Interventions window.<br />
2. Click the <strong>Radiation</strong> Prescription in the Diagnoses and Interventions window, then click<br />
