SRS/SBRT QA

Isocenter Optimization Routine (3D Winston-Lutz)

Automatically process a set of EPID Winston-Lutz images to give a fast, accurate measurement of isocenter position. RIT’s version of this classic test allows you to use 3 to 16 images, not only giving you an accurate measurement of isocenter displacement, but also an error estimate determining the wobble around the isocenter and any ball setup error. Increased angle flexibility allows you to mimic more clinically relevant angles to determine isocenter at specific treatment configurations

Eliminate your need for films, and increase your accuracy by using the all patented Virtual Starshot, reconstructed using a set of Winston-Lutz images!

Elekta Hancock Tests

Hancock Tests (Leaf and Jaw Positional Accuracy)


MLC and Jaw QA

The Hancock Test (2-Image Test, 4-Image Test, and With Backup Jaw Test) makes MLC and Jaw QA simple for Elekta machines. The test follows a simple image acquisition procedure on the iViewGT™ system, with automatic processing and reporting by RIT. This test has versions specifically-formatted for the Agility™ MLC head and the MLCi2 head. The Hancock Test encompasses several mechanical tests, including MLC position accuracy, jaw position accuracy, and takes into consideration iViewGT™ imager position movement and collimator rotation isocenter walkout. The Hancock Test results can be used as input data for adjusting the MLC and jaw calibration in the Elekta TCS (Treatment Control System). The RIT Hancock Test is the only system that meets the TG-142 requirement to measure backup jaw position relative to leaf position. The RIT system easily and seamlessly supports JPEG and HIS images from iViewGT™.

Track your results in the RITtrend™ database, or export them to PDF or Excel formats.

Elekta Leaf Speed Analysis

RIT offers enhanced MLC QA for Elekta machines, allowing for fast and accurate automated analysis, with minimal setup.

  • The Leaf Speed Analysis routine measures the consistency and accuracy of the MLC leaf speeds as they traverse the imager.
  • All measurements are made on your EPID, just like your treatment deliveries. Log files are not used, allowing for universal access.

SRS/SBRT QA

Isocenter Optimization Routine (3D Winston-Lutz)

The RIT Family of Products come equipped with an automated 3D Stereotactic Alignment routine, giving you a fast and accurate measurement of isocenter accuracy.  Using only a set of 3 to 16 EPID Winston-Lutz images, the RIT system will calculate deviations between radiation and mechanical isocenter, determine ball/BB setup error and suggest couch alignment adjustments to optimize your system’s accuracy.  Additionally, this routine enables individual component (gantry, collimator, couch) characterization to better understand distinct contributions to isocenter deviation, giving insight into adjustments that can be made to improve delivery performance, if needed. Increased angle flexibility allows you to mimic more clinically relevant angles to determine isocenter at specific treatment configurations.

Eliminate your need for films and increase your accuracy using Virtual Star Shot* with ANY combination of angles, reconstructed using a set of Winston-Lutz images in it’s new, dedicated window!
