Webb30 okt. 2024 · In slow CT, images were acquired in the axial mode, with a gantry rotation time of 4 s per slice and a 2.5-mm slice thickness. For 4D-CT, the scanner was operated in the axial cine mode. CT images with a 2.5-mm slice thickness were acquired with a 1-s gantry rotation time, a 0.4-s cine interval, and 6-s cine duration.

Webb1 nov. 2001 · Planning CT scans (slice thickness 3 mm, reconstruction index 2.5 mm) were performed during quiet respiration in 10 patients with peripheral lung lesions. Planning CT scans were repeated twice, followed by three slow CT scans (slice thickness 4 mm, index 3 mm, revolution time 4 s/slice). All, except the first scan, were limited to the tumor region. WebbConclusion: A slow CT technique was created that yields motion assessments that agree with 4DCT for a range of target motions. The technique involved averaging four slow CT scans. The averaged slow CT scans had an appearance similar to 4DCT AveIP data sets.
