Title:
最適化データ取得によりCT画質を最適化する方法及び装置
Document Type and Number:
Japanese Patent JP4675472
Kind Code:
B2
Abstract:
A method is described for optimizing signal-to-noise performance of an imaging system, including the steps of scout-scanning (116) an object to obtain scout scan data; determining (118) a plurality of normalized x-ray input signal factors using the scout scan data; using the normalized x-ray input signal factors to determine (120) at least one system input signal; selecting (122) at least one gain for the object scan using the system input signal; and applying the selected gain corresponding to the system input signal in the object scan.
