A coherent grid system of coordinates for precise anatomical localization

Specific localization in surface and topographical anatomy has always been on the basis of random, arbitrarily selected and unsystematized criteria. A coherent scheme is proposed as a prototype of a truly scientific approach. Using the earth's geographic coordinate system as a model, a similar lattice pattern of numbered transverse "lines of latitude" and lettered vertical "lines of longitude" was devised for the human body. To preserve metric consonance the grid was decimalized with 100 parallel transverse lines on the entire body and 10 essentially parallel vertical lines on any half of the body or on any limb. A body surface point can be symbolized by a very concise coordinate consisting of a combination of one or two numbers with one or two alphabetic letters. A few other very common everyday symbols used in conjunction with coordinates can vastly extend utility of the grid system to the precise determination of body surface lines, penetrating vectors, every kind of conceivable plane, and every spatial volume in and outside the body in any aspect desired. The grid is ideal for computerization. With a thoroughly coordinated ideal "body" thus committed to computer memory banks for random access at will, the stage will have been set for the advent of total automation of many medical and surgical procedures. Some kind of universal system as proposed is urgently needed if in the future medicine is to successfully meet the awesome challenge thrust upon it by the spectacular achievements of high technology.
