结局指标
主要结局
The quality of PI/PC and iDose4/ cardiac imaging reconstructed images was basically equal or above 3 score
时间窗: through study completion, an average of 2months
Scoring criteria 5 points The image quality of PI/PC is better than that of iDose4/ cardiac imaging, which can be used for diagnosis, very satisfied 4 points The image quality of PI/PC is better than that of contrast products, and the image of iDose4/ cardiac imaging can be used for diagnosis, satisfactory 3 points The image quality of PI/PC is basically equivalent to that of iDose4/ cardiac imaging. The image quality is defective, which does not affect the diagnosis, but is normal 2. The image quality of PI/PC is not lower than iDose4/ cardiac imaging, but the image quality is poor, which affects the diagnosis and is not satisfactory 1 points The image quality is lower than iDose4/ cardiac imaging after using PI/PC, the image quality is poor, cannot diagnose, unsatisfactory
次要结局
- Imaging reconstruction clarity using PI/PC compared with using iDose4/ cardiac basically equivalence to or above 3 score(through study completion, an average of 2months)
- Imaging reconstruction Noise level using PI/PC compared with using iDose4/ cardiac basically equivalence to or above 3 score(through study completion, an average of 2months)
- Imaging reconstruction enhancement condition using PI/PC compared with using iDose4/ cardiac basically equivalence to or above 3 score(through study completion, an average of 2months)
- Imaging reconstruction diagnostic confidence using PI/PC compared with using iDose4/ cardiac basically equivalence to or above 3 score(through study completion, an average of 2months)
- Imaging reconstruction Image texture using PI/PC compared with using iDose4/ cardiac basically equivalence to or above 3 score(through study completion, an average of 2months)
- Imaging reconstruction Image artifacts using PI/PC compared with using iDose4/ cardiac basically equivalence to or above 3 score(through study completion, an average of 2months)
