Outcome Measures

Primary Outcomes (1)

  • The quality of PI/PC and iDose4/ cardiac imaging reconstructed images was basically equal or above 3 score

    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

    through study completion, an average of 2months

Secondary Outcomes (6)

  • 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 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 Image texture using PI/PC compared with using iDose4/ cardiac basically equivalence to or above 3 score

    through study completion, an average of 2months

  • +1 more secondary outcomes

Study Arms (2)

Test Group

Using PI/PC reconstruct raw data

Other: CT Image reconstruction

Control Group

Using Idose4/Cardiac Image reconstruct raw data

Other: CT Image reconstruction

Interventions

Retrospectively collects CT Images and reconstruct using PI/PC and Idose4/Cardiac Images to assessment the performance of the two new software functions of Incisive CT. No direct intervention to patients. And ICF is exempted by EC.
