Figure 2

A. Four evenly-spaced point cores with S cm spacing between cores. The circumscribed circle depicts that largest spherical tumor, of diameter D T = S, that just grazes the point core. These contact points form a detection square, with sides S. B. Point core detection quadrant geometry, where D T /2 is the radius of a generalized tumor, superimposed on this detection quadrant.
