In vivo dosimetry seems an appropriate method for quality assurance in radiotherapy with CO-60, which can be considered as a routine program in radiotherapy centers. In this study, entrance and exit dose in tangential fields were measured in phantom for 30 breast cancer patients by using TLD in radiotherapy section of Imam Khomeini Hospital.

A practical and accurate generalized procedure to reconstruct the isocenter dose D(iso) for 3D conformal radiotherapy (3DCRT) has been developed for X-ray open beams supplied by linacs of different manufacturers and equipped with aSi electronic portal imaging devices (aSi EPIDs). This paper reports an extension of the method, to be applied at the wedged X-ray beams characterized by the wedge at...
