Extensive review of different dosimeters and detectors in small-field dosimetry

Abstract

Modern radiation techniques are frequently used in tiny, static areas in clinical settings. Modern radiation procedures employ many tiny fields to provide the appropriate dosage distribution and target coverage. Modern radiation procedures employ many tiny fields to provide the proper dosage distribution and target coverage. Small fields can introduce uncertainty into dosimetry, necessitating extra care in dose calculations and measurements. Specialized Dosemeters are required due to some difficulties, including finite source size, steep dosage gradients, charged particle disequilibrium, detector size, and the volume averaging effect in small field dosimetry. Because of radiotherapy's greater reliance on tiny fields, different detector and dosimetry recommendations are developed by different organizations. This review paper describes an overview of the latest trends and recommendations on commercially available detectors, yardstick for selection, recommendations for measurements, and discussion about their pros and cons with suitable publications.
