RIT EPID MLC

 
RIT EPID MLC

A software package that combines TG-142 Machine QA, MLC QA for Varian and Elekta linear accelerators, and EPID QA phantom analysis

 

RIT EPID MLC software consolidates several of RIT's innovative therapy products into one comprehensive package to perform MLC QA for Varian and Elekta machines, beam measurement Machine QA and EPID MV Imaging phantom analysis. The software utilizes a combination of powerful, robust routines in a user-friendly interface to maximize the efficiency and precision of your measurements. For added convenience, you can easily export your analysis data as customizable reports or to the RITtrend™ statistical database for large-scale tracking and trending over time.
   

MLC QA

Varian LINAC

  • EPID Picket Fence Test
    This routine automates the classic picket fence test.
     
  • EPID Leaf Speed Test
    Without the use of log files, this test measures the consistency and accuracy of Varian MLC leaf speeds as they move across an imager.
     
  • Automated Varian RapidArc® Tests
    Images may be taken at any distance from EPID, Film, or CR Images. RIT’s RapidArc QA routines support the Millennium 120, HD120 MLC, and Halcyon® MLC models. This includes:
    • RapidArc Test 0.1: dMLC Dosimetry
    • RapidArc Test 0.2: Picket Fence vs. Gantry Angle
    • RapidArc Test 1.1: Picket Fence During RapidArc
    • RapidArc Test 1.2: Picket Fence with Errors
    • RapidArc Test 2: Dose Rate and Gantry Speed
    • RapidArc Test 3: Leaf Speed
EPID Picket Fence
  


Elekta LINAC

  • Hancock Tests for Elekta Machines
    The Hancock Tests use the Elekta iView™ imager to automatically measure leaf position vs. isocenter position, and jaw leaf setback measurements. Tests include:
    • 2-Image Hancock Test
    • 4-Image Hancock Test
    • Hancock Test With Backup Jaws
       
  • EPID Picket Fence Test
    This routine automates the classic picket fence test.
     
  • Elekta Leaf Speed Tests
    These tests aligns two images to analyze the consistency of the leaf speed. Tests include:
    • EPID Leaf Speed Test for Elekta iView™
    • EPID Leaf Speed Test (Agility) for and Agility™
Hancock Test for Elekta
 


Other MLC Tests

  • Bayouth MLC Analysis (can be used for CyberKnife® MLC)
    Analyze MLCs that require leaf gaps between banks.
     
  • Generic (TG50) Picket Fence Test
     
  • Setup MLC Leaf Template

Machine QA

Beam Measurements

  • Auto Star Shot Analysis
    RIT’s Star Shot beam detection routine features a fully-automated one-click interface with robust and accurate detection algorithms. The 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. Beam center overlays on the beam profile plots provide a clear indication of the automated routine’s performance. The 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. If desired, the routine will also allow you to easily modify the settings to fine-tune the automated analysis by hand.
     
  • Radiation/Light Field Coincidence
    EPID images may be analyzed without a calibration file and with custom field sizes. Center location can be found by taking a BB, pinprick, or using an L-Rad Phantom.
     
  • Wedge Check
     
  • Output Constancy

  • Image Histogram
