Golden beam data provided by linear accelerator manufacturers should be used in the commissioning of treatment planning systems

In radiation therapy, dosimetry accuracy is an important factor which if compromised has the potential to impact acceptable clinical treatment outcomes. Dosimetry accuracy is afected not only by the quality of a linear accelerator's (linac's) commissioned radiation beam, but also on how well the commissioned linac radiation beam can be maintained to achieve the same or similar radiation characteristics as at commissioning time of the linac.
