A method for standardizing intensity modulated radiation therapy planning optimization for nasopharyngeal carcinoma
Background: To investigate a method for standardizing intensity modulated radiation therapy (IMRT) optimization for nasopharyngeal carcinoma (NPC), in order to reduce the influence of subjective factors. Materials and Methods: This study is based on example IMRT plans for NPC, which were randomly divided into data acquisition and data verification groups. Organs at risk (OARs) were analyzed for...
متن کاملRadiobiological Model-Based Comparison of Three-Dimensional Conformal and Intensity-Modulated Radiation Therapy Plans for Nasopharyngeal Carcinoma
Introduction: Radiobiological modeling of radiotherapy plans are used for treatment plan comparisons. The current study aimed to compare the three-dimensional conformal radiation therapy (3DCRT) and intensity-modulated radiation therapy (IMRT) plans for nasopharyngeal cancer using radiobiological modeling. Materials and Methods: This study was conducted on 10 patients with nasopharyngeal carci...
متن کاملDetermining appropriate timing of adaptive radiation therapy for nasopharyngeal carcinoma during intensity-modulated radiation therapy
BACKGROUND To determine appropriate timing of an adaptive radiation therapy (ART) replan by evaluating anatomic and dosimetric changes of target volumes and organs at risk (OARs) during intensity-modulated radiation therapy (IMRT) for nasopharyngeal carcinoma (NPC). METHODS Nineteen NPC patients were recruited. Each patient had repeat computed tomography (CT) scans after each five fractions a...
متن کاملClustering of nasopharyngeal carcinoma intensity modulated radiation therapy plans based on k-means algorithm and geometrical features
Background: The design of intensity modulated radiation therapy (IMRT) plans is difficult and time-consuming. The retrieval of similar IMRT plans from the IMRT plan dataset can effectively improve the quality and efficiency of IMRT plans and automate the design of IMRT planning. However, the large IMRT plans datasets will bring inefficient retrieval result. Materials and Methods: An intensity-m...
متن کاملVolumetric intensity-modulated arc therapy vs conventional intensity-modulated radiation therapy in nasopharyngeal carcinoma: a dosimetric study
Dosimetric comparisons between RapidArc (RA) and conventional Intensity-Modulated Radiation Therapy (IMRT) techniques for nasopharyngeal carcinoma (NPC) were performed to address differences in dose coverage of the target, sparing of organs-at-risk (OARs), delivery of monitor units (MUs) and time, to assess whether the RA technique was more beneficial for treatment of NPC. Eight NPC patients (S...
