Aiming at the inverse design of treatment planning for intensity modulated radiation therapy(IMRT),the multi-objective optimization model for IMRT was discussed.

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.

Intensity modulated radiotherapy for recurrent malignant gliomas after definite radiotherapy;

Dosimetric verification and clinical efficacy of intensity modulated radiotherapy in nasopharyngeal carcinoma

To compare IMRT treatment plan of nasopharyngeal carcinoma with conventional 3D conformal plan and two opposed fields plan;

Methods (1) To verify if the dose calculation of inverse plan was accurate, absolute dose at a certain point of the 42 cases patient s IMRT treatment plan were measured with water phantom transference in an ionization chamber so as to further make sure calibration factor of the inverse planning system.

Objective To analyze the therapeutic effects of postoperative three-dimensional conformal radiotherapy(3D-CRT) and intensity modulated radiotherapy(IMRT) for gliomas.
