In practical radiotherapy, it is important to deliver radiation to the target correctly and safely according to the
treatment planning. The control of radiation dose delivered to each patient in radiotherapy mainly relies on the
prediction based on the result of pre-treatment verification and irradiation accuracy of treatment machines. In
Vivo dosimetry in radiotherapy is the procedure of quality assurance by the way of direct measurement for the
patient whether the calculated prescribed dose in the treatment planning is delivered precisely. The history of In
Vivo dosimetry is relatively long, and the TLD dosimetry for clinical radiotherapy started in early 1970’s. After
1980’s, owing to the development of semiconductor devices such as diode detectors, semiconductor arrays, the
clinical applications for the dosimetry and diagnostic radiation imaging devices which contributed to the
development of electric portal imaging devices and 2D semiconductor detectors were introduced. In recent
years, these radiation measurement devices and non-invasive methods have been developed, they are becoming
widespread as clinical practice. In this paper, we reviewed the In Vivo dosimetry devices and their
characteristics, and technical application for radiotherapy.
