Figures

Image of FIG. 1.
FIG. 1.

Frontal views following 3D rendering of (a) UFH-NURBS 15-year-old male phantom and (b) UFH-NURBS 15-year-old female phantom. Body contours are made transparent for better viewing internal organs and the skeleton.

Image of FIG. 2.
FIG. 2.

Transaxial views (cross sections) of the UFH-voxel 15-year-old (a) male and (b) female phantoms.

Image of FIG. 3.
FIG. 3.

Coronal views (cross sections) of the UFH-voxel 15-year-old (a) male and (b) female phantoms.

Image of FIG. 4.
FIG. 4.

Sagittal views (cross sections) of the UFH-voxel 15-year-old (a) male and (b) female phantoms.

Image of FIG. 5.
FIG. 5.

Frontal views of 3D rendering of the 10th (left), 50th (middle), and 90th (right) weight percentile UFH-NURBS 15-year (a) male and (b) female phantoms.

Image of FIG. 6.
FIG. 6.

Lateral views of 3D rendering of the 10th (left), 50th (middle), and 90th (right) weight percentile UFH-NURBS 15-year (a) male and (b) female phantoms.

Image of FIG. 7.
FIG. 7.

(a) Top, (b) front, and (c) lateral views of 3D rendering of the arm-raised posture of the UFH-NURBS 15-year-old female phantom for chest and abdominal CT simulations. Arms, clavicles, and scapulae were modified from their original positions as shown in Figs. 3 and 4.

Tables

Generic image for table
TABLE I.

Reference anthropometric parameters for the 15-year male and female patient as obtained from various literature sources and the values realized in the final UF hybrid 15-year male and female phantoms.

Generic image for table
TABLE II.

Summary of organ masses within three different computational phantoms of 15-year-old male: (1) UF hybrid-NURBS, (2) UF hybrid-voxel, and (3) UF hybrid-voxel (CT). These masses are then compared to ICRP Publication 89 reference masses by organ, organ system, and for total body tissues (exclusive of walled-organ content) and total body mass (inclusive of walled-organ content).

Generic image for table
TABLE III.

Summary of organ masses within three different computational phantoms of 15-year-old female: (1) UF hybrid-NURBS, (2) UF hybrid-voxel, and (3) UF hybrid-voxel (CT). These masses are then compared to ICRP Publication 89 reference masses by organ, organ system, and for total body tissues (exclusive of walled-organ content) and total body mass (inclusive of walled-organ content).

Generic image for table
TABLE IV.

Normalized values of organ absorbed does (mGy/100 mA s) calculated from the reference ORNL 15-year phantom, and the 10th, 50th, and 90th weight percentile UF hybrid 15-year-old male phantoms for chest and abdominal CT exams. The ratios of organ doses between the ORNL and 50th percentile phantoms, 10th and 50th phantoms, 90th and 50th phantoms are given.

TABLE V.

Normalized values of organ absorbed dose (mGy/100 mA s) calculated from the reference ORNL 15-year phantom, and the 10th, 50th, and 90th weight percentile UF hybrid 15-year-old female phantoms for chest and abdominal CT exams. The ratios of organ doses between the ORNL and 50th percentile phantoms, 10th and 50th phantoms, and 90th and 50th phantoms are given.
