Abstract
|
|
|
|
The Winston Lutz test, which checks the accuracy of the isocenter for stereotactic radiosurgery (SRS), was performed with the commercial electronic portal imaging device (EPID). The usual Winston Lutz test with film was also performed for comparison with the test with EPID. The maximum difference in isocenter between the two methods was 0.32 mm. The Winston Lutz test using EPID is practical as it can reduce time and avoid human errors compared to the test with film.
