Typical bitmap image demonstrating the four regions (soft tissue, bone tissue, lung tissue, and air) used in this phantom.
A series of images illustrating the construction sequence for a slice including soft tissue, bone tissue, and air. (a) The bitmap template. (b) The homogenous soft tissue blank has had regions that will contain bone and air removed and has been shaped to the desired outline. (c) Bone tissue-equivalent material is introduced into the appropriate voids.
Soft tissue outlines for phantom slices containing lung and corresponding saved transparency lung regions.
Lung slice after bone introduction, prior to sanding.
Lung slices after sanding and with MOSFET channels milled to create completed slices.
Frontal view of the completed phantom, with arms.
Lateral view of the completed phantom, without arms.
Locations selected for dosimeter placement in the tomographic physical phantom. Locations in are always used in effective dose measurements, while other locations may be included as required.
