Size specific dose estimate (SSDE) for estimating patient dose from CT used in myocardial perfusion SPECT/CT [PDF]

Asia Oceania Journal of Nuclear Medicine and Biology, 2020
Objective(s): Size specific dose estimate (SSDE) is a new parameter that includes patient size factor in its calculation. Recent studies have produced mixed results on the utility of SSDE, especially when automatic exposure control (AEC) was used.

Estimating size specific dose estimate from computed tomography radiograph localizer with radiation risk assessment. [PDF]

J Appl Clin Med Phys, 2023
Background Quantifying radiation burden is necessary for optimizing imaging protocols. The normalized dose coefficient (NDC) is determined from the water‐equivalent diameter (WED) and is used to scale the CTDIvol based on body habitus to determine the ...

SIZE-specific dose estimate for lower-limb CT

Physical and Engineering Sciences in Medicine, 2022
Abstract The Computed Tomography Dose Index (CTDI) is an indicator for dose management in computed tomography (CT), but has limited use for patient dosimetry. To evaluate the patient dose, the size-specific dose estimate (SSDE), reported by the American Association of Physics in Medicine task groups 204, 220, and 293, must be calculated by the ...

Correlations Between Body Weight and Size-Specific Dose Estimate on Thoracic Computed Tomography Examination

Atom Indonesia, 2022
The dose received by a patient on CT examination is expressed in size-specific dose estimates (SSDE) which is a function of the patient diameter, x-ray attenuation, and scanner output (volume computed tomography dose index, CTDIvol). Patient diameter and
