Résumé

To evaluate the performances of the Dolphin system for pre-treatment verification (IBA Dosimetry, Schwarzenbruck, Germany) based on transmission measurements, employing a clinical perspective. Fifty treatment plans were verified by Dolphin and Delta A value of 10.7% ± 0.7% was found for detector attenuation. No patients were classified as "fail" by the two instruments as well as by physicians. No correlation was found between the Delta The Dolphin system demonstrated to be an accurate detector for pre-treatment purposes and could be used as a clinical decision making tool for plan acceptance.
