It is recommended that DRLs be measured at least once a year. This study aimed to evaluate the long-term fluctuations of fluoroscopic dose rate in an angiography system.Methods: An unconnected X-ray output analyzer was used to measure the fluoroscopic dose rate (air kerma rate) at the patient's entrance reference point for a specific angiography system. The target period was from 2015 to 2022, and four measurements per year were made. First, the fluoroscopic dose rate was measured, and the average value and standard deviation for the target period were calculated. Next, the uncertainty of the measured values and the coefficient of variation were calculated. Finally, we calculated the fluoroscopic dose rate measurement error.Results: The average±standard deviation of the fluoroscopic dose rate was 353.29±9.11 µGy/s. The maximum uncertainty and coefficient of variation for each year were 5.41 µGy/s and 0.03, respectively. The maximum measurement error was 4.67%, where the mean measured value was taken as the true value.Conclusion: The fluctuation in the measured value of the fluoroscopic dose rate by an angiography system for 8 years is within ±5%, indicating stable X-ray output.","PeriodicalId":74309,"journal":{"name":"Nihon Hoshasen Gijutsu Gakkai zasshi","volume":" ","pages":"1296-1304"},"PeriodicalIF":0.0,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142576839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In terms of dose management, information regarding the imaged body part is particularly important information for proper tabulation. However, the actual body part to be imaged and the body part information obtained from the device may differ. In this study, we investigated the difference between the imaged area information obtained from a CT device and the dose index when the area is divided into actual areas to be examined using a facility's unique imaging protocol. We collected 734784 radiation dose structured reports (RDSR) examined from 2014 to 2021 on CT equipment at 8 facilities and analyzed each facility's volume CT dose index (CTDIvol) and dose length product (DLP). The median values were tabulated and compared. Pre- and post-classing the body part, for CTDIvol, increasing tendency was observed only in the head and abdomen. A similar trend was observed for DLP. Regarding dose management using RDSR as an information source, there were no major differences in dose information depending on the classification of the body part to be imaged. We hope that the accuracy of dose management will be improved by accurately classifying the body parts to be imaged.","PeriodicalId":74309,"journal":{"name":"Nihon Hoshasen Gijutsu Gakkai zasshi","volume":" ","pages":"1322-1327"},"PeriodicalIF":0.0,"publicationDate":"2024-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142634066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
