What's New in V6.6 and Earlier

THE RIT FAMILY OF PRODUCTS: Version 6.6 & Earlier

Version 6.6 of the RIT Family of Products (Radia Version 1.10) was released on June 27, 2017.

 

Machine QA

3D Winston-Lutz Isocenter QA

The RIT Family of Products come equipped with an automated 3D Stereotactic Alignment routine to give you a fast and accurate measurement of isocenter position. Using only a set of EPID Winston-Lutz images, the RIT system will calculate isocenter displacement, determine wobble around the isocenter, and suggest couch position adjustments to optimize your system’s accuracy. Eliminate your need for films, and increase your accuracy by using the all new Virtual Starshot, reconstructed using a set of Winston-Lutz images!*

Updates from Version 6.6:

  • Updated 3D Winston-Lutz analysis interface makes relevant measurements  more visible and intuitive.
  • Analysis automatically determines ball setup error, providing analysis results both with and without setup error contribution.
  • Use Virtual Star Shot* with ANY combination of angles in its dedicated window.
  • The couch optimization routine includes tabs for intuitive visualization of adjustment outcome.
  • Organize measurement table results to pinpoint minimum and maximum values.
  • PDF report includes footnote definitions to easily interpret analysis results.


Updates from Version 6.5:

  • All collimator angles are supported.
  • “Old Varian” and Siemens coordinate systems are supported.
  • Optimization of region-of-interest routine for automatic field size detection.
  • Improvements to the Axis Projection screen

Updates from Version 6.4:

  • Eliminate your need for films, and increase your accuracy by using the Virtual Starshot, reconstructed using a set of Winston-Lutz images!*

Updates from Version 6.2:

  • Added the ability to choose amongst a number of alternate coordinate systems within the routine, so that the results are relevant to your system’s configuration.

Updates from Version 6.1:

  • RIT’s version of this classic test allows you to use 3-10 images and not only gives you an accurate measurement of isocenter displacement but also an error estimate to determine the wobble around the isocenter.
