Abstract
At Centre for Medical Radiation Physics, semiconductor diode as dosimeters for radiotherapy and mixed radiation fields were developed and tested. Now a day, measurement and verification of the dose quantity given to the patient is most important for the better results in the clinical practice for that quality assurance of clinical dosimeter is essential in radiotherapy technique. In this study a solid-state diode detector used for measurement of dose given to the cancer patient in radiotherapy techniques for that indigenous developed phantom used for quality assurance with diode detector. In this study we used the photon beam of energy 6 MV and 15 MV and kept focused on the linearity, dose rate dependence and angular dependence of diode. The diodes exhibit angular dependence in the range from 0.98 to 1.01. It was observed that studied diode exhibited good dose linearity which was independent of dose rate at very minimal angular dependency. Also, it is observed that the directional properties of studied diode have very good response. The studied diode has excellent response with high energy beam with respective to linearity, dose rate dependence and angular dependence. Solid state diode has better application of dosimeter in cancer treatment.
