摘要：

To test the basic dosimetry characteristics of a new high-resolution matrix and to perform a preliminary study on the three-dimensional (3D) dose verification of intensity-modulated treatment (IMRT). The dosimetry characteristics of the new matrix were investigated, including repeatability, dose-rate response, and dose linearity. Twenty cases of nasopharyngeal carcinoma (NPC) and 20 cases with lung cancer were randomly selected for IMRT plans, and the novel matrix was employed for 3D dose verification. The measured results were evaluated using ...
