SNC Machine™ listens for and captures your QA files, processes and analyzes the files, and saves the results to the database. Simply log in to the application and immediately view a dashboard of results. Accept results that pass, and drill down into the analysis details for results that fail. Trend any piece of data against any other piece of data. It is that simple, and that powerful.
All TG-142 recommended imaging and mechanical tests for monthly QA are included with SNC Machine. Simply deliver the test beam and SNC Machine does the rest. Accept or reject results on your terms and timeframe.
TG-142
All VMAT tests recommended by Varian are included with SNC Machine.
VMAT
19 different tests for TG-142 & VMAT QA
SNC Machine Dashboard presents all recently executed tests. Failed tests are highlighted red. Approve the tests from the dashboard or click the test to drill down and scrutinize the results.
In this MLC Picket Fence test, failed leaves are highlighted as are the pickets that failed.
Results and images for a Star Shot Test with automatically calculated circle diameter and spoke angles.
Results and images for a Winston-Lutz Isocenter Test. View the 2D results for each image as well as the combined 3D results of all images.
Create trend graphs from any test result and easily compare trends using a single graph.
Results and images for a CBCT Test. Rollover any thumb nail to see the parameters and the specific corresponding ROI’s to ensure image registration was performed correctly.
Trend and compare the test parameter against other test parameters from any number of machines. Easy to read graphs display trend lines relative to custom tolerances.
