Figure 3 Violin plot comparison of objective image quality parameters between the photon-counting computed tomography and energy-integrating detector computed tomography groups. A: Signal-to-noise ratio; B: Contrast-to-noise ratio; C: Signal-to-noise ratio/(computed tomography dose index)^1/2; D: Contrast-to-noise ratio/(computed tomography dose index)^1/2; E: Noise ratio; F: Excellent image index. SNR: Signal-to-noise ratio; CNR: Contrast-to-noise ratio; CDTI: Computed tomography dose index; EID-CT: Energy-integrating detector computed tomography; PCCT: Photon-counting computed tomography; NR: Noise ratio; EII: Excellent image index.
