The volume can then be approximated with the Riemann sum A(x1)Ax++ A(xn)Ax, where n is the number of scans, Ax is the space between scans, and A(x) is the area of the organ given by the ith scan. For example, this technique is used extensively to detect potential enlargement of the spleen. Now assume we are trying to determine the volume of an interval organ. We perform 20 CT scans at 0.5cm intervals and find the following cross-sectional areas (in cm2): 0, 1, 2, 2.5, 3, 3, 4, 5, 8, 10, 12, 11, 11, 10, 10, 8, 7, 6, 3, 1. Using this data estimate the volume of the internal organ.
