Different Dosimeters/Detectors Used in Small-Field Dosimetry: Pros and Cons
DOI: 10.4103/jmss.JMSS_3_18
Abstract
fields is needed. Using such field sizes can cause uncertainty in dosimetry; therefore, special
attention is required both in dose calculations and measurements. There are several challenges in
small-field dosimetry such as the steep gradient of the radiation field, volume averaging effect, lack
of charged particle equilibrium, partial occlusion of radiation source, beam alignment, and unable
to use a reference dosimeter. Due to these challenges, special dosimeters are needed for small-field
dosimetry, and this review article discusses this topic.
