Dose reconstruction for real‐time patient‐specific dose estimation in CT

Purpose: Many recent computed tomography (CT) dose reduction approaches belong to one of three categories: statistical reconstruction algorithms, efficient x‐ray detectors, and optimized CT acquisition schemes with precise control over the x‐ray distribution. The latter category could greatly benefi...
