RITG148+
RIT is your best source for comprehensive Helical TomoTherapy® Radixact® QA tests in TG-148
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.
Machine QA
TomoTherapy® Measurements
Please note that bold text below indicates the test name according to Accuray, and the test name in parenthesis is the corresponding test name in TG-148.
- Beam Planarity and Jaw Twist (Y-Jaw Divergence/Beam Centering and Y-Jaw/Gantry Rotation Plane Alignment)
- MLC Twist and Center of Rotation (MLC Alignment)
- Jaw Symmetry (Treatment Field Centering)
- Couch Travel Distance (Couch Translation/Gantry Rotation)
- Overhead Laser Position (Laser Localization)
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. - Helical Gantry Angle (Gantry Angle Consistency)
This analysis has been revised to improve the rotational invariance. Rotation of images is no longer needed. - Static Gantry Angle
- Interrupted Treatment
- IGRT Alignment
- Import TomoTherapy® DICOM Film Files
- Import TomoTherapy® Calibration Files
- Vidar TIFF Export

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.

Built-In Features in RITG148+
RITG148+ includes RITtrend™ – the all-in-one statistical database tracking solution, that stores data for all your department's measurements. Set your own specifications and RITtrend automatically analyzes process control limits on equipment analyzed with RIT software. The multi-source data manager gives you even more control for reporting on your entire medical physics program. RITtrend redefines database recording into a major tool for analysis and record-keeping in your department.
RITtrend™ is a trademark of Radiological Imaging Technology, Inc.
RITG148+ includes 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.
RITG148+ Complete includes 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.
