Objective To find the optimal radiotherapy for prostate cancer through comparison of intensity modulated radiotherapy and three-dimensional conformal radiotherapy(3D-CRT) technique.

The study on brachytherapy instrument and intensity modulated conformal therapy instrument;

Radiotherapy instruments are used for the treatment of tumor by ionizing radiation, mainly including stereotactic radiation therapy; microwave electron linear accelerator ; Brachytherapy and intensity modulated conformal therapy system.

Scintigraphic Assessment of Parotid Function Prior to and after IMRT for Pantients with Nasopharygeal Carcinoma;

A Clinical Study of Intensity Modulated Radiation Therapy(IMRT) Combined with NP Regimen Chemotherapy in the Treatment of Middle-Advanced Non-Small Cell Lung Cancer;

Intensity modulated radiation therapy for brain tumors;

Intensity modulated radiation therapy for 49 patients with recurrent nasopharyngeal carcinoma;

Objective To evaluate the therapeutic effects of intensity modulated radiation therapy(IMRT)in combination with hormonotherapy in the treatment of intermediate and advanced prostate carcinoma.

Objective: To systematically evaluate intensity-modulated radiation therapy(IMRT) used to treat non-small cell lung cancer, investigate the conformity index (CI), heterogeneity index (HI), the dose to organs at risk(OARs), and evaluate the difference in the IMRT plans using five, seven, and nine beams.

Quality assurance for intensity-modulated radiation therapy(IMRT)is an importantissue to study.

With the development of image technology,functional imaging was gradually applied to contouring the gross target volume,which generated the concept of biological target volume and biological intensity-modulated radiation therapy.
