This paper describes a high speed string correction method using a hierarchical file. After reviewing a string correction method based on the Levenshtein distance, a hierarchical file construction method is introduced. A multistage string correction method using this file is proposed. The lower bound of computational complexity is estimated, and it is shown(More)
The purpose of this study was to determine the outcomes and optimal practice patterns of definitive radiotherapy for primary vaginal cancer. Between 1993 and 2012, 49 patients were treated with definitive radiotherapy for primary vaginal cancer in three hospitals. Of these, 15 patients (31%) had clinically positive regional lymph node metastasis. A total of(More)
PURPOSE To compare the outcome of our facility with another about the shortened schedule (60 Gy in 10 fractions to 54 Gy in 9 fractions) of high-dose-rate interstitial brachytherapy (HDR ISBT) for mobile tongue cancer. MATERIAL AND METHODS Eighteen patients were treated with HDR ISBT as a monotherapy in dose reduction schedule with some unique technique(More)
To investigate the feasibility of image-based intracavitary brachytherapy (IBICBT) for uterine cervical cancer, we evaluated the dose-volume histograms (DVHs) for the tumor and organs at risk (OARs) and compared results from the IBICBT plan and the standard Manchester system (Manchester plan) in eight patients as a simulation experiment. We performed(More)
