A comparison between manual and artificial intelligence –based automatic positioning in CT imaging for COVID-19 patients

ConclusionThe AI-based automatic positioning and centering in CT imaging is a promising new technique for reducing radiation dose and optimizing imaging workflow and image quality in imaging the chest.Key Points• The AI-based automatic positioning (AP) operation was successful for all patients in our study.• AP method reduced the total positioning time by 28% compared with the manual positioning (MP).• AP method had less patient off-center distance and higher proportion of positioning accuracy than MP method, resulting in 16% radiation dose reduction and 9% image noise reduction in erector spinae.
