Fig. 1From: Image quality improvement using model-based iterative reconstruction in low dose chest CT for children with necrotizing pneumoniaAverage number and standard deviation of objective image noise of 4 algorithms on different tissues. Images were 0.625 mm in thickness unless stated otherwise. Le: consolidated lesion; Nec: necrotic area; Mus: muscle; Air: background air around body. ※ Significant difference of image noise compared with the 0.625 mm MBIR imageBack to article page
