Autor: Alexa E. Golbus, John L. Schuzer, Chloe Steveson, Shirley F. Rollison, James Matthews, Joseph Henry-Ellis, Marco Razeto, Marcus Y. Chen

Publikováno v: European Journal of Radiology Open, Vol 13, Iss , Pp 100578- (2024)

Purpose: Traditional CT acquisition planning is based on scout projection images from planar anterior-posterior and lateral projections where the radiographer estimates organ locations. Alternatively, a new scout method utilizing ultra-low dose helic
