Institutional computed tomography diagnostic reference levels based on water-equivalent diameter and size-specific dose estimates

Journal of Radiological Protection, 2018
Abstract S ize-specific institutional diagnostic reference levels (DRLs) were generated for chest and abdominopelvic computed tomography (CT) based on size-specific dose estimates (SSDEs) and depending on patients’ water-equivalent diameter (Dw).

Size Specific Dose Estimate Based on Water-Equivalent Diameter for Common Head Ct Examinations: A Monte Carlo Study

2022
The Computed tomography dose index (CTDI) is an unreliable dose estimate outside of the standard CTDI phantom diameters (16 and 32 cm). Size-specific dose estimate (SSDE) for head CT examination was studied in the American Association of Physicists in Medicine (AAPM) report 293 to provide SSDE coefficient factors based on water equivalent diameter as ...

A SIMPLE METHOD FOR CALIBRATING PIXEL VALUES OF THE CT LOCALIZER RADIOGRAPH FOR CALCULATING WATER-EQUIVALENT DIAMETER AND SIZE-SPECIFIC DOSE ESTIMATE

Radiation Protection Dosimetry, 2017
The purpose of this study is to establish the relationship between the pixel value (I) of the CT localizer radiograph and water-equivalent thickness (tw) in a straightforward procedure. We used a body CTDI phantom, which was scanned in the AP and LAT projections. After transformation from the pixel values of the images to tw, water-equivalent diameter (
