RITG148 Plus Software


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
    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.
