“…For instance, their small size allows them to be placed inside narrow BT catheters inserted in the tumor region, and real-time monitoring of the detector response facilitates online error detection. The response of ISDs to absorbed dose in water is, in contrast to that of PSDs, dependent on the photon energy spectrum (Rogers 2009), while both ISD and PSD responses exhibit temperature dependence (Edmund and Andersen 2007, Beddar 2012, Wootton and Beddar 2013, Buranurak et al 2013). However, the energy and temperature dependences can be corrected for with fairly straightforward methods (Wootton and Beddar 2013, Reniers et al 2012).…”
