Fig. 4From: Toward a priori noise characterization for real-time edge-aware denoising in fluoroscopic devicesStatic frames from the real fluoroscopic sequences. The frames shown in the first and second rows were acquired at 50Â mA and 10Â mA (40 kVp), respectively. The frames in the left column depict the TOR-18FG phantom, while those in the right column depict the TOR-CDRBack to article page
