GAFCHROMIC EBT2
• Self developing - eliminates the processor• Energy independent dose response• Near tissue equivalent• Dose range:
Red Channel 1 – 800 cGy Green Channel: 8 – > 50 Gy
• 8”x10” and 14”x17” sheets• High spatial resolution• Can be handled under indoor lighting• Scan with either flatbed scanner or medical scanner• Water resistant – usable in water phantoms• High uniformity (+/- 3% maximum in dose)• Economical• Blue Channel to be used for film uniformity correction
for even higher accuracy in future releases of the FILMQA software.
Ball Cube II Film and Phantom Placement
Procedure
FilmQA in Six Easy Steps1. Import Calculations
– From treatment planning system
2. Import Films– Using flatbed or medical scanner
3. Register – Automatic orientation of films
4. Calibrate– Convert to dose images
5. Evaluate– Compare calculations to films
6. Create Reports – Customizable in HTML Format
