2 Available TG-148 Products DoseLab RITG148 Y-jaw divergence/beam centering Y-jaw/gantry rotation plane alignment Treatment field centering MLC alignment test Gantry angle consistency Couch speed uniformity Couch translation/gantry rotation Interrupted treatment Laser localization Cheese phantom image quality Y-jaw divergence/beam centering Y-jaw/gantry rotation plane alignment Treatment field centering MLC alignment test Gantry angle consistency Couch speed uniformity Couch translation/gantry rotation Interrupted treatment Laser localization Cheese phantom image quality Is DoseLab right for my clinic? DoseLab is able to provide the metrics required for tests: Some test are multi-step Require the use of a spreadsheet for final calculation User will utilize Custom Tests for data entry Best method for testing DoseLab workflow is with Demo license User Guides are easy-to-follow Provide us with feedback we truly investigate suggested workflow optimizations via user input 2

3 DoseLab stands out We are the only easily automated linear accelerator software (with AutoQA setup) that has this capability Sites with linear accelerators AND TomoTherapy units this opens doors that are otherwise closed TG-148 tests are for annual performance Workflows for TomoTherapymachine QA will easily be recuperated with our software automation for TG-142 QA of linear accelerators Customer-driven integrations Introduction to the Quick Guide 12 page User Guide Two sections Prior to guide usage, it is recommended the user is familiar with TG-148 Imaging setup and techniques not discussed Refer to TG Report 3
