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