Title:
ノイズ軽減のための適応投影フィルタ処理スキーム
Document Type and Number:
Japanese Patent JP4371403
Kind Code:
B2
Abstract:
A method and system for reducing noise in an x-ray image generated by an imaging system using an adaptive projection filtering scheme (100) including generating system information (102), obtaining original projection data (104), determining a data characteristic of the original projection data (106), processing the original projection data responsive to the system information and the data characteristic so as to create filtered projection data (108) and calculating resulting projection data responsive to the filtered projection data (110). Also claimed is a medium encoded with a machine-readable computer program code for reducing noise in an x-ray image generated by an imaging system, the medium including instructions for causing the controller to implement the aforementioned method.
