Machine QA
Daily, Monthly, and Annual Machine QA for LINACs
- Enhanced 3D Winston-Lutz (Isocenter Optimization) with Virtual Star Shot*
Automatically process a set of EPID Winston-Lutz images for a fast and accurate measurement of isocenter position. RIT’s version of this test allows you to use 3 to 16 images, and provides error estimates for ball setup and wobble around isocenter. Increased angle flexibility allows you to mimic more clinically relevant angles to determine isocenter at specific treatment configurations. *US Patent 9192784, JP Patent 6009705, CA Patent 2918045, and other international patents pending.

MLC QA
Varian LINAC
- EPID Picket Fence Test
This routine automates the classic picket fence test.
- Automated Varian RapidArc® Tests
Images may be taken at any distance from EPID, Film, or CR Images. This includes: Tests 0.1, 0.2, 1.1, 1.2, 2, and 3. RIT’s RapidArc QA routines support the Millennium 120, HD120 MLC, and Halcyon® MLC models.
- Varian Leaf Speed Test
Without the use of log files, this test measures the consistency and accuracy of Varian MLC leaf speeds as they move across an imager.
- Varian Halcyon® MLC Analysis
Perform a picket fence or comprehensive RapidArc® analysis of the Halcyon® MLC.
Elekta LINAC
- Hancock Tests for Elekta Machines
The Hancock Tests (2-Image Test, 4-Image Test, and With Backup Jaw Test) use the Elekta iView™ imager to automatically measure leaf position vs. isocenter position, and jaw leaf setback measurements.
- EPID Picket Fence Test
This routine automates the classic picket fence test.
- Elekta Leaf Speed Test
This test aligns two images to analyze the consistency of the leaf speed for both Elekta iView™ and Agility™.
Other MLC Tests
- Bayouth MLC Analysis
Analyze MLCs that require leaf gaps between banks.
- Additional MLC Tests
These include: TG-50 Picket Fence Test, MSK Leaf Test, Varian DMLC Test Patterns, and MLC Transmission analysis.

Custom Tolerance Management
Use the Tolerance Manager to set tolerance values and pass/fail criteria for every measurement used in all automated phantom analyses. This tool provides the flexibility necessary to customize tolerances on a wide array of LINACs and imaging systems:
- Conveniently set and toggle between tolerances in an easy-to-use panel, located in the main interface, and displayed in every phantom analysis routine.
- Set your own PASS/FAIL criteria for analyses and their corresponding reports, allowing for complete customization in all imaging QA analyses.
- Preference profiles and tolerances are set on a per-machine basis. They can be precisely-tailored to each individual machine in use.
- Transfer all PASS/FAIL tolerance data to the RITtrend™ database for statistical tracking and trending.
