  • Notes supplémentaires dans les données
    When a CT phantom is scanned and the images are transferred to Monaco, it is possible to sample the densities using the Image Statistics tool. In the case where the thickness of the CT slice is not equal to the spacing of the CT slice, the Image Statistics tool will report an incorrect HU. If you base your CT-to-ED file on this incorrect density information, this will result in errors in the calculation of the dose. The magnitude of the error in the dose calculation will depend on the magnitude of the HU error. The problem occurs when the CT Slice Spacing is not equal to the CT Slice Thickness, and the Image Statistics tool information is used to populate the CT-to-ED file. According to the company's risk assessment, Monaco will assign an incorrect density that will lead to errors in the dose, which can result in adverse consequences without serious health.
