Volume averaged CT dose index (CTDIvol) is an important dose index utilized for CT dosimetry. Measurements of CTDIvol are performed in reference cylindrical phantoms of specified diameters. A size-specific dose estimate (SSDE) has been recommended for assessment of doses delivered to individual patients.

Journal of Radiological Protection, 2021
Abstract The actual dose received during a computed tomography (CT) examination depends on both the patient size and the radiation output of the scanner. To represent the actual patient morphometry, a new radiation dose metric named size-specific dose estimates (SSDEs) was developed by the American Association of Physicists in ...

Size specific dose estimates in pediatric chest, abdomen and pelvis CT examinations
Physica Medica, 2016Introduction Volume computed tomography dose index (CTDIvol) does not contain any dose information regarding the patient size. Size specific dose estimates (SSDE) give more reliable results accounting for the patient size as well. This parameter uses CTDIvol and size dependent conversion factors (fDw) which are calculated by means of water equivalent ...

The CT dose index (CTDIvol) is the dosimetric quantity used for multi-slice CT (MSCT) with beams ⩽4 cm. Conversion factors (f size) based on patient size are applied to CTDIvol to adjust for differences in patient size and derive size-specific dose ...

Evaluation of Size Correction Factor for Size-specific Dose Estimates (SSDE) Calculation
Japanese Journal of Radiological Technology, 2016American Association of Physicists in Medicine (AAPM) Report No.204 recommends the size-specific dose estimates (SSDE), wherein SSDE=computed tomography dose index-volume (CTDIvol )×size correction factor (SCF), as an index of the CT dose to consider patient thickness.

Evaluation of Size-Specific Dose Estimates in Pediatric Abdominal CT
Korean Society of Computed Tomographic TechnologyIn pediatric abdominal CT examinations, the conventional CT dose index (CTDIvol) has limitations as it does not account for the patient’s body size. To address this issue, the American Association of Physicists in Medicine (AAPM) introduced the concept of size-specific dose estimate (SSDE), which considers individual patient body size.

Introduction and evaluation of size-specific DLP for radiation dose estimation in CT examinations
Journal of Radiological ProtectionAbstract The increased utilization of computed tomography (CT) has raised concerns about patient radiation exposure. Effective dose (ED), which requires precise estimation, is crucial for assessing and managing these risks. Traditional ED estimation methods, which are based on the dose-length product (DLP), often lack accuracy due to ...
