   RITG135 Software

An innovative and dedicated software package for all your CyberKnife® machine QA needs. The automated routines and analyses ensure rapid results, without compromising precision.


Assembled to coincide with recommended QA tasks outlined within TG-135, the RITG135 software package includes analyses for the End-to-End, AQA, Iris, Laser Coincidence, and M6 MLC Tests. Designed to simplify and enhance current methods for performing these routine tasks, RITG135 provides a user-friendly interface with minimal user interaction, reducing the likelihood of errors and ensuring reproducible measurement templates.Automated film detection algorithms eliminate the need for manual manipulation or alignment of images, significantly reducing the time needed to perform these tests. Easily create PDF reports for either individual or combined routines, and export to our RITtrend database for simple tracking and trending of results over time.

TG-135 recommends eight tests for daily QA, thirteen tests for monthly QA, and eleven tests (plus the daily and monthly tests) for annual QA.

End-to-End Test

The End-To-End (E2E) test verifies the mechanical accuracy of the robot, the tracking method, and the dose. To perform this test, RITG135 software handles:

  • Ball Cube phantom
  • Ball Cube 2 phantom
  • Mini-Ball Cube phantom

Individual films or “three-in-one” (Axial, Sagittal, and background in a single scanned image) are also used. Alignment and rotation for Ball Cube 2 images is performed automatically, using cutouts on the film. Additionally, RITG135 software can use dose-calibrated images for the utmost accuracy.

AQA Test

The AQA test is an isocentric-targeting accuracy test that can be used with calibrated or uncalibrated images. TG-135 recommends that this test be performed daily. RITG135’s AQA test generates a significant amount of daily data that can be tracked and trended in the RITtrend™ statistical database.

RITG135 Iris

Iris Test

The CyberKnife machine has fixed collimators and a IRIS collimator. RITG135 software can compare commissioning IRIS or fixed collimator measurements (baseline) to current measurements for each IRIS or collimator size. On a monthly basis, measured values are compared to baseline values to perform QA on the IRIS size and beam characteristics of small fields.


Laser Coincidence Test

The Laser Coincidence test uses film or a CR plate to check the coincidence of the center of an IRIS or fixed collimator with the CyberKnife central axis laser.

Other Machine QA Measurements

  • Orthogonal Profiles
  • Import TomoTherapy® Calibration Files


Fully Automated M6 MLC Test

RITG135’s fully-automated “Garden Fence” MLC test has the ability to greatly increase the efficiency of MLC tests for CyberKnife units with a M6 muliti-leaf collimator.

Although MLC tests are not specified in TG-135, as this was not an option for CyberKnife machines when the task group report was developed, the most significant advantage of this test is in its automated processing. Rather than using multiple products from different vendors, RITG135 consolidates your MLC tests into a single software package.

RITG135 software will:

  1. Automatically crop the image.
  2. Automatically align the image.
  3. Perform automatic orientation of any images that are rotated or flipped.
  4. Automatically detect any leaves, eliminating any need for template files.
  5. Perform the analysis.

According to experts at Accuray, you can save an average of 30 minutes per film with RITG135 software.
