Description for medicine or protocol of treatment in detail: |
Automatic Tube Voltage Modulation, automatic tube voltage modulation, ATVM) combined with Artificial Intelligence Iterative Reconstruction (AIIR) algorithm and conventional tube voltage combined with KARL 3D Iterative Reduction (KARL 3D Iterative Reduction, ATVM) algorithm To compare the image quality and radiation dose of chest, abdomen and pelvis enhanced CT with Karl-3D IR (KARL-3D IR) algorithm, and to optimize the optimal noise level of AIIR in chest, abdomen and pelvis enhanced CT. Different patients with different chest, abdomen and pelvis underwent enhanced spectral CT scanning with the optimized scanning protocol. The spectral CT image data were analyzed on AW4.7 workstation, and the CT value, SNR and CNR were measured, calculated and extracted. Subjective and objective image quality evaluation data. |
