X-Tream dosimetry of synchrotron radiation with the PTW microDiamond

In this study, we demonstrate that the X-Tream dosimetry system developed by the Centre for Medical Radiation Physics can be used with both commercial and non-commercial dosimeters. A custom adaptor was constructed to connect the PTW microdiamond to the X-Tream DAQ. This allowed for the measurements of continuous depth dose curves, broad beam and microbeam profiles. The X-Tream system enables real time measurement of the instantaneous dose rate of synchrotron generated radiation with the PTW microDiamond. Finally, measurements undertaken in this study demonstrate that the X-Tream system is able to mitigate the alignment issue that has previously hampered the uptake of the PTW microdiamond in clinical quality assurance for small field dosimetry.
