   RITG142 Software

The single-vendor solution for every image-based test recommended in TG-142 and MPPG 8.b. Perform comprehensive quality assurance of linear accelerators with confidence and ease, using an EPID and RITG142 software.


RITG142 is your all-in-one solution for Machine QA, MLC QA, Imaging QA, and the data tracking and trending you need to be in compliance with TG-142 and Medical Physics Practical Guideline (MPPG) 8.b for comprehensive LINAC QA. In addition, imaging QA phantoms are automatically scored with easy to use tracking and trending functions.

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.

    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.
EPID Picket Fence

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.

RunQueueC logo

The imaging QA capabilities in RITG142 include RunQueueC – the fully automated batch phantom analysis tool. RunQueueC is an automated feature included in all RIT software packages with imaging QC capabilities. With one click, easily perform analysis on any number of images. RunQueueC will automatically generate analysis reports in a designated folder and export data to the RITtrend database for statistical tracking and trending over time. 

Cerberus logo

The imaging QA capabilities in RITG142 include Cerberus – the hands-free batch phantom analysis tool. Cerberus constantly operates in the background of your workstation, automatically monitoring folders and pin-pointing specific files to process and analyze. It can match many set criteria, such as file naming patterns, DICOM tag matches (up to 4 DICOM tags may be used), or file types. Cerberus automatically performs analyses, generates reports, and shares data to RITtrend, using specific parameters set in your customized preference profiles (including tolerances) to analyze the images for all of your machines.
