Physics Bucharest 2017

Pre-Measurement Preparation

• Sometimes it is the only time that physicists can extensively measure radiation beams and beam modifiers

• All in-house dosimetry equipment should be checked for calibration, accuracy, and availability • Mechanical motion of water tank • Noise and leakage of ionization chambers and diodes • Phantom check

• Errors in these phases may affect many patients! • BUT DON’T FORGET PATIENT-SPECIFIC QA
