Development and Current Status of a Chest X-ray Interpretation Exercise System for Lung Cancer Screening

━━ Based on a questionnaire survey, the Lung Cancer Screening Committee considers that the aging of doctors involved in lung cancer screening and the high coverage rate of non-specialist doctors are problems; thus, the acquisition of new reading doctors and maintaining and improving the reading ability for doctors who currently perform reading, are considered very important. In 2012, we published Chest X-ray Interpretation Text-book for Lung Cancer Screening with the aim of solving these problems; however, we needed a method to apply the knowledge learned there. In 2018, screening image data were collected from facilities related to the Lung Cancer Screening Committee members, and the image data were evaluated by central judgment. Based on the data and results, we have developed a system that enables interpretation exercises similar to the examination interpretation environment. In May 2019, it started operation as a system that members can practice anytime and any-where via the internet. It is now stably operated at more than one year after the start of operation. This paper ex-plains the progress of the development of this system and how it is used. It also reports the usage status. ( JJLC. 2021;61:69-76)
