RIT Classic Software

RIT's original software product for Machine QA, MLC QA, and Patient QA, developed to enable medical physicists to perform all necessary analyses.

 

Balance your need for efficiency and responsibility for accuracy with RIT Classic. RIT Classic is RIT’s original software product package, developed to enable Medical Physicists to perform all the necessary analyses with both efficiency and accuracy in Machine QA, MLC QA, and Patient QA. RIT Classic is one of the few products on the market that has the capability to analyze images from all sources, including EPID, 2D arrays, film (Vidar and flatbed scanners), gel, and CR.

MACHINE QA

Daily, Monthly, and Annual Machine QA for LINACs

  • Enhanced 3D Winston-Lutz (Isocenter Optimization) with Virtual Star Shot*
    Automatically process a set of EPID Winston-Lutz images for a fast and accurate measurement of isocenter position. RIT’s version of this test allows you to use 3 to 16 images, and provides error estimates for ball setup and wobble around isocenter. Increased angle flexibility allows you to mimic more clinically relevant angles to determine isocenter at specific treatment configurations.
