摘要：

Detectability and impact of potential treatment machine errors on IMRT treatments were evaluated. The ability of the gamma index to detect deliberately introduced errors was assessed and their clinical impact was assessed using Tumour Control Probability (TCP) and Normal Tissue Complication Probability. TCP was only marginally affected by 2 mm errors in MLC position. Dose delivery errors had greater impact but were not detected as effectively using the gamma index. Acceptance criteria should include mean dose as well as gamma to help identify errors in the delivered dose. (C) 2011 Elsevier Ireland Ltd. All rights reserved.
