Abstract

Techniques for amelioration of the effect of maximum mA limits that are imposed with the primary intention of reducing patient dose but have the undesirable effect of reducing the level of quality in the final reconstructed image volume are provided. The techniques achieve this by (1) recognizing that some or all view angles have suboptimal mA levels compared to those determined automatically by the AEC algorithm, and (2) redistributing the mA levels as a function of view angle to maintain as closely as possible the cumulative dose to the patient for the entire scan.
