Setup Checklist – Image Owl

Under Manage Sites & Machines, edit the Linac to and select SAD or SSD for photons. At this time SSD is the only selection for Electrons.
Under Manage Sites & Machines, edit the Linac to set factors for photons:

Enter the SSD or SAD
Enter the depth
Enter the field size
Select the energies used on the Linac
For SAD setup enter Clinical TMR _{(depth, field size)} factors for selected energies or for For SSD setup enter Clinical %dd(depth) factors for selected energies
Enter expiration dates (optional)

Under Manage Sites and Machines, edit the Linac to set factors for Electrons:

Enter cone size.
Select either Calculate from I₅₀ or Enter R₅₀ method
Enter I₅₀ or R₅₀ factors
Enter PDD (d_ref, cone size) factors
Enter expiration dates (optional)

Create an electrometer in measurement devices and set the P_elec and any setting notes under calibration.

Create the Ion chamber to be used for the TG-51 report in measurement devices:

Either select a predefined chamber or create your own by providing the cavity radius and the k_ecal.
Under calibrations enter the N^60_Co_D,wfactor for the chamber
Under calibrations enter the machine-specific k_Q (photons) and k'_R50 (electrons) factors

Add the TG-51 schedules to the Linac. The available templates will depend on the SAD/SSD selection in step 1 above.

In schedule settings you may want to preset the measurement conditions and change the voltage settings. Note do not preset the actual voltage readings.
