Abstract
|
|
|
|
Accuracy control of Linear accelerator installed in OBI is done daily and weekly and importance of accuracy multiplies exponentially at that moment. Purpose of this experiment is everyday and twice a week over a four month period (march~june) 2009 year to confirm maintenance of accuracy through Quality control of OBI. In short, measurement of exponentially multiplying accuracy of OBI and regular accuracy control was able to maintain accuracy from the center of treatment within 0.1 cm. Therefore, evaluation of exponentially multiplying accuracy using OBI accuracy control linear accelerator phantom on daily, weekly basis was confirmed.
