Abstract

Solid state detectors with nanosecond response timesto incoming radiation are increasingly present at the forefrontof radiotherapy dosimetry research. The fast response time ofmaterials, such as diamond, allow pulse by pulse dosimetry. Thereis a trend in radiotherapy to move towards shorter treatmen...
