1. An anatomy display method comprising: obtaining an anatomy dataset comprised of pixels, each of said pixels having a luminance, said pixels being arranged in slices; selecting a portion of said anatomy dataset; choosing at least one slice of said portion of said anatomy dataset; establishing a threshold luminance within said portion of said anatomical dataset; zeroing all pixels below said threshold in said selected portion of said anatomy dataset; isolating a selected organ; and saving a volumetric matrix of said pixels corresponding to said selected organ; measuring a lesion volume and a negative width and length; wherein step of measuring lesion volume is comprised of: scanning each of a plurality of rows of pixels in turn; identifying consecutive zero values in each of said rows having zero values; deleting said rows of pixels for which a summed number of pixels having a zero value in excess of said threshold; rescanning the rows of pixels remaining after said step of deleting; and summing the number of pixels having zero values remaining.
