Patient QA
As a leading innovator in precision automated QA, Radiological Imaging Technology® developed the first automated IMRT (Intensity-Modulated Radiation Therapy) analysis, now commonly referred to as Patient QA. RIT's Patient QA analyses provides clinical physicists with the tools necessary to analyze this advanced cancer treatment, thereby participating in the rapid availability of this treatment, both in the United States and worldwide.
General Patient QA
EPID QA: Cut Out the Middle Machine
Rotational Therapy & IMRT
- Eliminate unnecessary middle-step image capture devices
- Save $20,000 to $150,000 in purchase price alone
- Cut costs for repair, replacement, and service contracts from your budget
- Significantly improve your QA results with higher resolution and 64-bit processing
- Perform the easiest, most precise QA analysis routines available
- Speed up your QA procedures even more using RunQueueA batch analysis
General Patient QA highlights include:
- Isodose
- Distance-to-Agreement (DTA)
- Gamma Function
- Subtraction
- Centroid Measurement
The newly-added Centroid Plot compares two images and measures any shift between the centroids. This is an excellent way of quantifying any alignment or setup errors between two images. This routine is conveniently-located within the main Patient QA interface.
- Automated Image Fill for Anthropomorphic Phantom QA
Use this newly-added function in the ‘Edit’ menu to automatically correct and fill any holes or cutouts in the image file. Perform patient QA with an anthropomorphic phantom for both calibrated and uncalibrated images. This feature supports a wide variety of anthropomorphic phantoms, including those used for CyberKnife® patient QA.
PDF Export Options
Easily export the results of all patient QA measurements, including those performed in RIT's automated batch analysis feature, RunQueueA, to a customizable PDF report to display your most significant data.
TomoTherapy Registration
Easily perform exact dose comparisons for TomoTherapy® Patient QA. The new, innovative wizard uses a TomoTherapy® plan, a dose map, and a film to determine position and dose accuracy, using the red or green lasers. (NOTE: Currently, green lasers are only supported for Accuray Precision® 2.0.0.0 and above treatment planning systems.) This automated technique extends standard registration methods, as the isocenter location is not required to be in the center of the exposed dose region. Coronal or Sagittal slices may be analyzed. Utilize RIT’s patented Plan-Based Calibration technology with this routine.
The routine now allows a structure to display as an overlay ROI. You can conveniently select a specific structure from any of the plan structures and display the Structure Outline on the image. Any structure in the Accuray Precision® plan may be used (e.g., PTV). Now, your analysis can be limited to the structure of your choosing, plus a user-defined margin, if preferred. You can then use RIT’s Patient QA routines to measure your results (Gamma, Subtraction, DTA, or one of 28 other analysis routines) within the ROI.
This routine only supports the following Accuray Treatment Planning Systems:
- TomoH V 5.1.3 Build 5.1.3.9
- Precision® 1.1.0.0 Build 56037

Plan-Based Calibration for TomoTherapy® Registration
Utilize RIT’s patented* Plan-Based Calibration technology to simplify your TomoTherapy Registration process for patient QA. With Plan-Based Calibration, a calibration file is no longer needed, the scanner warm up is minimized, and variation in development time after exposure is no longer a significant factor. This saves you time and money, and could potentially improve patient throughput. Additionally, there is no longer a need for blue or green channel corrections, eliminating a complicated and cumbersome multi-channel correction process.
Plan-Based Calibration is also a more accurate method (normalization within 1 cGy), as it is precisely tailored to each specific film, with as many data points as the user needs. It accounts for variation between film and scanners and generally increases passing capability. New guidance for tighter tolerances in TG306, TG-148’s replacement task group, raises the bar on gamma passing criteria. Plan-Based Calibration can increase the accuracy of this test, and your gammas are more likely to improve.

Plan-Based Calibration
RIT's patented Plan-Based Calibration routine gives you the ability to make quick relative or absolute comparisons between any dose map and your Film, EPID, CR and ion chamber array images! Using any dose map images (no special patterns needed), another image can be calibrated. Overlaying this calibration with an existing absolute calibration can give you a measurement of the overall accuracy. This technique can be used to eliminate field size dependencies in film, EPID and CR images. It can also be used with an ion chamber array to produce fast absolute dose calibration at a multitude of points.

Other Modalities
3D Gels and Solids
Take advantage of a full 3D data set by using 3D Gels and Solids with the RIT Family of Products software packages. Whether you use your own 'octopus' tomographic laser scanner, or send your gel to MGS research to be scanned, you can import those files into RIT software for dose analysis. MGS claims resolutions up to 0.3 mm per slice.
CR
The RIT Family of Products fully support digital images from the Kodak / Carestream 2000RT and other CR equipment. DICOM files are easily converted to RIT format, giving you the complete palette of the RIT Family of Products routines and functionality. You get the precision of RIT dosimetry and the ease of a filmless system.
Film
Precision is the entire point of IMRT, IGRT, and VMAT. For many years, film dosimetry was the gold standard tool for the high resolution images that are the cornerstone of QA testing. Although many of our users have transitioned to using their EPID with the RIT Family of Products, film is always an option. Speed and efficiency are critical to a busy treatment center, but obtaining the most accurate dose analysis possible is the real responsibility.
