1. A computer-implemented method to determine placement of transducers on a subject's body, the computer comprising one or more processors and memory accessible by the one or more processors, the memory storing instructions that when executed by the one or more processors cause the computer to perform the method, the method comprising:
selecting a plurality of intersecting line segment pairs on an image of the subject's body, each of the line segment pairs intersecting in a region of the image corresponding to a tumor in the subject's body, each of the line segment pairs corresponding to locations to place the transducers on the subject's body;
determining a pair value for each of the intersecting line segment pairs, each pair value based on a length of each line segment of the corresponding intersecting line segment pair, wherein determining the pair value for each of the intersecting line segment pairs comprises calculating an absolute value of a difference between lengths of the line segments of the corresponding intersecting line segment pair;
selecting one or more intersecting line segment pairs based on the pair values to obtain one or more selected intersecting line segment pairs; and
outputting the locations to place the transducers on the subject's body corresponding to the one or more selected intersecting line segment pairs.
