Research Progress of Two-dimensional Matrix Detectors in IMRT Dose Verification

With the continuous development of science and technologies in China, radiotherapy technology medical field has been very significantly developing, intensity modulated radiation therapy (IMRT) most widely used. This paper first introduces components types two-dimensional matrix detector, ionization chamber detector semiconductor then analyzes dosimetric characteristics detector. In end, various applications are analyzed discussed detail. The aims to promote detector’s China.
