Review on small field detectors for stereotactic radiotherapy
The lack of lateral charged particle equilibrium,the obstruction of the primary photon source,and limited detectors available for small field measurements challenged the modern radiotherapy technology for small field dosimetric measurement,greatly affecting the accuracy of dosimetry.The excessive radiation accidents indicate a lack of understanding of appropriate methods for small field dosimetric measurement.Herein an overview on various types of detectors that are suitable for small field dosimetric measurement,including micro-ionization chamber,semiconductor detector,diamond detector,plastic scintillator,radiochromic film,thermoluminescent detector,radio-photoluminescent glass,optically stimulated luminescent detector,polymer gel dosimeter is provided for offering a reference for physicists in selecting small field detectors.
