Claim 16:
17. A system for generating a view of an interior of an object, the system comprising:
a scanner for scanning the object;
a processing circuit; and
a display,
the processing circuit being configured to:
calculate a first threshold, based on a median of a plurality of maximum values in a first target point in a first slice; and
generate a first contour,

the first contour being a boundary of a first region,
the first region being a region within which:
elements of the first slice are greater than the first threshold, or
the elements of the first slice are less than the first threshold;
generate a centroid for the first contour and save the generated centroid in a memory;
generate a second contour in a second slice, based on a second target point in the second slice, wherein:
the first slice is a first slice of a scan volume, and
the second slice is a second slice of the scan volume, the second slice being adjacent to the first slice, and wherein

the processing circuit calculates the second target point as the centroid of the first contour, and generates the second contour by generating the second contour in a search area centered on the second target point; and
remove artifacts from the first slice by calculating a horizontal moving sum along a row of the first slice and a vertical moving sum along a column of the first slice, and selecting a moving filter for the moving sums to be comparable to or wider than a thickness of the artifacts to be removed to remove the artifacts.
