[Evaluation of Clinical Practicability of Hybrid Automatic Treatment Planning for Nasopharyngeal Carcinoma].

Objective: Automatic planning is a commonly used alternative to manual planning. This study evaluated the clinical performance of automatic plans available in commercial treatment planning systems for nasopharyngeal carcinoma (NPC) treatment by comparing automatic planning with manual planning.

Methods: A total of 14 patients with nasopharyngeal carcinoma were enrolled in the study.

Evaluation of Daily CT for EPID-Based Transit Dosimetry.

Purpose: The difference in anatomical structure and positioning between planning and treatment may lead to bias in electronic portal image device (EPID)-based dosimetry calculations. The purpose of this study was to use daily CT instead of planning CT as a reference for EPID-based dosimetry calculations and to analyze the necessity of using daily CT for EPID-based dosimetry calculations in terms of patient quality assurance.

Materials And Methods: Twenty patients were enrolled in this study.
