Abstract The dosimetry of small photon fields is the theoretical basis for the calculation accuracy of real physical dose in precise radiotherapy such as stereotactic radiotherapy, stereotactic radiosurgery and intensity modulated radiotherapy. Compared with conventional beam, small fields incline to introduce larger error in clinical application with increasing dose uncertainty. In order to ensure the small fields measuring accuracy and the specialized detector usage standardization, a clinical practice guideline of small fields dosimetry was established under the organization and leadership of National Cancer Center/National Cancer Quality Control Center with the cooperation of many large medical institutions in China. This guideline mainly covers the clinical procedures of reference dose and relative dose measurements in small static photon fields, thus domestic radiotherapy units can apply small field related radiotherapy technology safely, reliably, efficiently, and accurately.
