Image Test Generator — Kaptan Data Solutions

Your image will appear here.

Choose an imager and a template, then adjust the settings — or press “Generate the image”.

How it works

  1. Choose a portal imager (AS1200, AS1000 or AS500): it sets the image size and pixel pitch.
  2. Pick a template — open field, off-centre field, Winston-Lutz (with an optional FFF cone), VMAT fields, Picket Fence, Starshot — or build a custom image from a circle, a square and a BB.
  3. Adjust the sliders: the image is regenerated each time. Set the SID and the gantry, collimator and table angles written in the DICOM header.
  4. Download the image as DICOM (RT Image) or PNG, ready to feed your QA software.
