Radiation dosimetry and clinical out come

Dosimetry plays a vital role in the field of radiation oncology. Any radiation event is a probabilistic function. Hence an error can be expected and accepted. Any error in the dose delivery, dose prescription affects the clinical outcome for the patient. Dose delivery depends on the dose measurement and QA Program of the department. In the era of IMRT and VMAT, leakage measurement through the jaws and MLC leaves, becomes important. Choice of dosimeter plays a vital role in the error. Still the studies are going in the field of small field dosimetry and choice of dosimeters, dose verification systems need to be evaluated carefully based on the type of treatments carried out
