Fig. 6 — Dose reduction of photon counting CT using an excised vertebral body. Single energy CT: 120 kV, 355 mAs, 23.8 mGy, Photon counting 120 kV, 130 mAs, 10.5 mGy. The image noise (σ) is identical in both scans with a reduction of radiation exposure by more than 2 in the case of photon counting. For both scans, comparable high-resolution kernels were used [97]
