PET Interpretation Support Method by Store and Retrieval of Confirmed Diagnosis Data Using DB Hironori AOKI̐. Masaru UEDA̐. and. Takashi TOMIȊ. ̐Department of Information Media and Environment Sciences, Graduate School of Environment and Information Sciences, Yokohama National University ̑Faculty of Environment and Information Sciences, Yokohama National University 79-7 Tokiwadai, Hodogaya-ku, Yokohama 240-8501 Japan E-mail: ̐{d06hc001, d05hc008}@ynu.ac.jp, ̑[email protected] Abstract In recent years㧘diagnosis by whole-body PET (Positron Emission Tomography) images are considered as an effective method of finding cancer. We have proposed a modeling method to share these proper knowledge with doctors by using a database. In this paper, we propose PET interpretation support method by modeling DB to store confirmed diagnosis data and retrieval of confirmed diagnosis information at the PET interpretation. Firstly we considered required function of a system for integrating PET diagnosis information and confirmed diagnosis information. As for the result, we implemented prototype of the system ,and also evaluated the effectiveness of it.
