Automatic Deep Learning Based Calculation of Water Equivalent Diameter from 2D CT Localizer Image [PDF]
2021 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2021 With the increasing number of CT scans being obtained, ensuring as low as reasonable exposure is coming to the fore. One critical fact affecting the personalized radiation dose is the patient's size and attenuation characteristics, which can be addressed by water equivalent diameter (DW). This study proposed an automatic method to calculate the DW from

Dependence of Water-equivalent Diameter and Size-specific Dose Estimates on CT Tube Potential. [PDF]
Radiology, 2022 Background The size-specific dose estimate (SSDE) is a patient-focused CT dose metric. However, published size-dependent conversion factors (fsize) used to calculate SSDE were determined primarily by using phantoms; only eight to 15 patient data sets were used, all at 120 kV.

Comparison of methods to estimate water-equivalent diameter for calculation of patient dose. [PDF]
J Appl Clin Med Phys, 2018 AbstractModern CT systems seek to evaluate patient‐specific dose by converting the CT dose index generated during a procedure to a size‐specific dose estimate using conversion factors that are related to patient attenuation properties. The most accurate way to measure patient attenuation is to evaluate a full‐field‐of‐view reconstruction of the whole ...
