Second experimental measurements with Cyberknife at Birmingham. Green scintillator thin sheet measurements only.
Setup
Schematic
Photos of setup
(Inside pelicase, outside pelicase, collimators, through pelicase window)
Pre-data Taking Information and Notes
- Used 200mmx200mmx2mm green scintillator sheet polystyrene base sandwiched by two 200mmx200mmx50mm polystyrene clear plastic blocks
- 53cm from lens to sheet
- Check camera in focus with ruler on the sheet
- Near/Far limit of focus 49.4cm 57.1cm calculated using https://dofmaster.com/dofjs.html
- Pelicase on couch
- Scintillator blocks aligned to laser cross hairs
- 785 mm source to surface distance suitable for output factor/PDD/profile measurements.
- Room lights out and pelicase window open.
- Check optical axis aligned with top surface using crosshair in the image analysis.
- Arrived at hospital at 11am, finished data taking at 5pm
Data Taking
- All images taken with Nikon D7000, 20mm lens, f/2.8, 400ISO
- Used camera control pro 2 app
- Image of ruler taken at sheet for pixels to mm conversion
- 5 images taken at each collimator size with 1 background image each.
- Change exposure time until near max saturation - get's best bit depth
