GPU-based fast cone beam CT reconstruction from undersampled and noisy projection data via total variation
GPU-based fast cone beam CT reconstruction from undersampled and noisy projection data via total variation
Purpose: Cone-beam CT (CBCT) plays an important role in image guided radiation therapy (IGRT). However, the large radiation dose from serial CBCT scans in most IGRT procedures raises a clinical concern, especially for pediatric patients who are essentially excluded from receiving IGRT for this reason. The goal of this work …
