A Cobalt-60 treatment unit was equipped with a new collimator with asymmetrical capability of both the X-and Y-jaws. This new collimator design opens possibilities for treatment techniques with this apparatus, which, until now, were only achievable with linear accelerators. Before accepting the device and taking it into clinical routine, a dosimetric verification was performed, which compared results of dose measurements with the results of dose calculations of the treatment planning system… CONTINUE READING
