Isocenter Optimization Routine (3D Winston-Lutz)

Now with accuracy surpassing sub-pixel resolution!

The RIT Family of Products come equipped with an automated 3D Stereotactic Alignment routine to give you a fast and accurate measurement of isocenter accuracy, allowing you to optimize your SRS/SBRT delivery. Automatically process a range of 3 to 16 EPID Winston-Lutz images for fast, sub-pixel level accuracy of isocenter position. This routine allows physicists to perform daily or patient-specific analyses using specific clinical treatment angles. Using only a set of 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. RIT's Isocenter Optimization routine allows for optimal cone detection, resulting in the utmost precision.

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 its dedicated window! Patents: US 9192784, JP 6009705, CA 2918045, and other international patents pending.

 

   

Recently-Added Enhancements:

  • Isocenter Optimization for Elekta Unity
    RIT’s popular 3D Winston-Lutz (Isocenter Optimization) routine now supports analysis on the Elekta Unity machine, an MR-LINAC machine that combines diagnostic quality MR imaging with a linear accelerator. Elekta users can now utilize RIT’s most popular analysis routine to automatically process a set of EPID Winston-Lutz images for fast, sub-millimeter accuracy of isocenter position.
  • Automated File Name Generation
    RIT's 3D Winston-Lutz routine now includes the new Automated File Name Generation feature. The file name for PDF and ASCII analysis results will be automatically exported and generated with a timestamp and pass/fail status of results. This will save users time and improve workflow efficiency.
  • Updated Interface
    When analyzing a range of 3 to 16 images with RIT’s 3D Winston-Lutz routine, all images are now featured in the same interface window. This eliminates the need for any scrolling and ensures a comprehensive picture of your analysis results, all in one place.
  • More Flexible Pass/Fail:
    Users may now choose to pass or fail on the Maximum Machine Deviation (R) or the Total Maximum Deviation (W), which includes the ball setup error

Fully-Automated Star Shot Analysis

RIT’s film Star Shot beam detection routine has been completely re-designed and now features a fully-automated interface with more robust and accurate detection algorithms. A few key highlights include:

  • Full Automation: Increase your efficiency and accuracy with RIT's one-click analysis of Star Shot images. The new algorithm removes pre-processing from your workflow, allowing for quicker acquisition of results. Polarity, ROI, number of spokes, and spoke center are all automatically extracted from the image, then applied in the analysis.
  • Visualized Spoke Detection: Newly-added beam center overlays on the beam profile plots provide a clear indication of the automated routine’s performance.
  • Artificial Intelligence: The re-designed routine utilizes sophisticated AI algorithms for even more accurate and reliable measurements. The AI obtains a 99% accuracy rate of spoke detection in a wide range of Star Shot images.
  • Manual Override Option: If desired, the routine will also allow you to easily modify the settings to fine-tune the automated analysis by hand.

The Best Source for Helical TomoTherapy® and Radixact® QA

 

 

RITG148+ is a precise, state-of-the-art, and comprehensive software built to perform all machine and imaging QA analyses for helical TomoTherapy®. Designed with the TG-148 report in mind, RITG148+ analyzes the standardized tests, including Static & Rotational Output Consistency, Jaw Centering & Alignment, Overhead Laser Positioning, Interrupted Treatment, and all others recommended for daily, monthly, and annual QA. RITG148+ also analyzes image quality, using the Tomotherapy Cheese phantom.

RITG148+ software's combination of powerful, robust routines in a user-friendly interface maximize the efficiency and precision of all measurements. For added convenience, users can easily create PDF reports for all routines, as well as export their data to the RITtrend database for large-scale analysis over time.

Recent Enhancements:

  • Static Gantry and Helical Gantry Angle Invariance
    The Static Gantry Angle and Helical Gantry Angle analyses have been revised to improve the rotational invariance. In RIT's updated software, rotation of these images is no longer needed.
  • Increased Overhead Laser Flexibility
    The Overhead Laser analysis can now handle smaller films in RIT's updated software. A full 12.8"x17" film is no longer required in order to perform this analysis.
