WE‐A‐301‐11: Low Dose Multi‐Slice Helical CT Reconstruction Using Tight Frame Regularization

Purpose: Multi‐slice helical CT has been widely used in CT diagnostic imaging due to its large coverage and short acquisition time. However, the associated high x‐ray radiation dose has become a major concern. Two straightforward ways to reduce the dose is to lower the mAs level and use high pitch....
