Transverse image of the UF male phantom showing the (a) right colon, (b) left colon, (c) small intestine, (d) right kidney, and (e) left kidney.
Frontal views of the UF series of pediatric computational phantoms. Each of the three rows gives views of the phantom exterior, the skeletal system, and the internal organ structure, respectively. Image columns correspond to the 9-mo male, the female, the female, the male, and the male, respectively.
A comparison of corresponding transverse images within the revised ORNL phantom and the UF male phantom.
Plots of phantom organ masses in comparison to their ICRP 89 age-dependent reference organ masses. The organs shown include those with proposed tissue weighting factors of 0.12 (breasts, colon, lungs, stomach wall) or 0.05 (urinary bladder, esophagus, gonads, liver, and thyroid).
Plots of phantom organ masses in comparison to their ICRP 89 age-dependent reference organ masses. The organs shown include those with proposed tissue weighting factors of 0.01 (brain, kidneys, salivary glands) or are part of the remainder tissues (gall bladder, heart, pancreas, small intestine, spleen, and thymus).
Dose coefficients (absorbed dose per unit air kerma free-in-air) for organs in the ORNL and stylized phantoms and in the UF male tomographic phantom. Three organs are considered: stomach wall (row 1), thyroid (row 2), and urinary bladder wall (row 3). The four irradiation geometries include: AP (column 1), PA (column 2), LLAT (column 3), and RLAT (column 4) directions.
Computed tomography image sources for the development of the UF pediatric phantom series.
Sitting heights of UF phantoms compared to NHANES III survey.
Organ and tissue masses for the UF pediatric computational phantom series. For those organs segmented directly within the patient CT images, percent differences are given between the patient organ mass and the corresponding interpolated ICRP 89 reference organ mass. Percent differences are not shown for those organs where the ICRP 89 reference mass was targeted during segmentation , or when no reference mass is available for comparison.
