Design outcomes

Primary

MeasureTime frame
Volumetric Computed Tomography Dose Index and Dose Length Product are the DRL quantities suggested by the guidelines. Effective Dose will be calculated by multiplying Dose length product with the region specific conversion factor. The diagnostic reference level value obtained in this study can be used to establish National diagnostic reference levels.Timepoint: 12 months (Feb 2025 to Feb 2026)

Secondary

MeasureTime frame
Image quality Analysis and typical value to establish diagnostic reference levelTimepoint: 12 months (Feb 2025 to Feb 2026)
