Evaluation of multiplanar imaging capabilities of four current computed tomography (CT) scanners

Published

Journal Article

Four state of the art CT scanners were evaluated with respect to optimal techniques for multiplanar imaging. The four scanners were a G. E. 8800, Pfizer 0^50, Picker Synerview 600 and Siemens Somatom 2. Patient movement artefacts can be minimized by choice of techniques that provide rapid data acquisition. By deferring reconstruction, using batch mode acquisition, suppressing screen display and operator interaction and minimizing tube loading as many as 33 thin slices can be acquired in < 8 minutes. This rapid scan technique makes use of the narrow collimation over a large (5-0 cm) distance quite reasonable. A high contrast star resolution phantom was scanned using these rapid scan techniques. The multiplanar Images produced from narrow slices are much higher resolution than those created with more widely collimated slices. A low contrast (2.5%) resolution object scanned with the same rapid acquisition method shows improved resolution for the narrow collimation even in the presence of increased noise accompanying the narrow collimation. © 1981 SPIE.
