Calculation process of the relationship between phantom’s diameter and height. The segmented pixels (black) for each line were computed and stored (A). The index corresponding to the image-matrix column and the number of black pixels were scaled according to the CT’s resolution and consequently matched. A proportional increase of the diameter traversing from apex to base of a cone is shown in (B), thus each diameter can be assigned to a certain height. After smoothing, the resulting height was normalized using the known center of gravity as origin and saved in a diameter/height lookup-table.
