정위적 방사선수술용 X-Knife 시스템의 의학물리적 QA에 관한 연구

By virtue of the stringent requirements on the accuracy in numerical and spatial dose delivery to the target volume in radiosurgery, it is obvious that a quality assurance (QA) program has to be in place wherever radiosurgery is used clinically. From a technical point of view, stereotactic radiosurgery consists of a chain of two single procedures. The two procedures are : (a) stereotactic target localization QA ; (b) treatment setup QA. Each of these procedures were tested by a separate QA program. The error of stereotactic target localization was within ±0.3mm compared to the value of specific Radionics Software Application (RSA) CT phantom. And the error of treatment setup verifying was within 1.2mm KCI Citation Count: 0
