SNC Machine

Automate Your Machine QA

  • TG-142 & VMAT Test Libraries
  • Automated QA File Capture & Analysis
  • Works with Varian, Elekta, Aria®, MOSAIQ®


Complete Automation

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.

TG-142 & VMAT Imaging and Mechanical QA

All image-based tests for TG-142 imaging and mechanical QA, plus VMAT 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

  • Image Quality (CBCT, kV, MV)
  • MLC (Picket Fence, Log File Positioning, Leaf Speed, Hancock MLC)
  • Winston-Lutz Isocenter (Radiation, Machine, Hancock Winston-Lutz)
  • Star Shot (Gantry, Couch, Collimator)
  • Light / Radiation Field Congruence
  • Beam (Field Size, Flatness, Symmetry)

All VMAT tests recommended by Varian are included with SNC Machine.

VMAT

  • Dose Rate versus Gantry Speed
  • Leaf Speed
  • Arc Point Dose
  • DMLC Point Dose

SNC Machine in Action

19 different tests for TG-142 & VMAT QA

Dashboard

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.

MLC Picket Fence

In this MLC Picket Fence test, failed leaves are highlighted as are the pickets that failed.

Star Shot

Results and images for a Star Shot Test with automatically calculated circle diameter and spoke angles.

Winston-Lutz

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.

SNC Machine Trending

Create trend graphs from any test result and easily compare trends using a single graph.

CBCT

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.

Trending

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.
