Radiotherapy detectors have advanced and changed over the years and it’s important to be aware of their uses and functionality. Optically Stimulated Luminescence Dosimeters (OSLDs) are now used frequently for routine clinical point-dose measurements because they offer high precision and are easy to use. These dosimeters are versatile, and OSLD have also been used to measure dose in brachytherapy, imaging, and calibration applications. Since the introduction of radiochromic films (RCF) for radiation dosimetry, the scope of RCF dosimetry has expanded steadily to include a wide array of medical applications in radiation therapy and diagnostic radiology. More recently, the multichannel RCF data analysis method has introduced a new standard for external beam treatment QA with its high accuracy and efficiency. This presentation will provide comprehensive guidelines on RCF dosimetry for various clinical applications. Radiochromic film is an excellent tool for planar measurements, but comes with its own set of considerations for successful implementation. Plastic scintillators are now available can be very useful for radiotherapy detection.
Learning Objectives:
1. To learn about the clinical use of OSLDs for radiotherapy detection including best uses and drawbacks
2. To outline the procedures to achieve measurement accuracy with an RCF dosimetry system and introduce the paradigm shift to multichannel film dosimetry
3. To describe the use of plastic scintillators in clinical radiotherapy and how to best incorporate this detector in routine clinical practice
