A method for non-mechanically linking the motions of an x-ray source with an x-ray receptor during a tomographic procedure to produce a tomograph of a section of an object under examination comprising the steps of: effecting motion of said source and receptor to respective reference positions; thereafter during a tomographic procedural mode generating from at least one fixed frequency signal source first and second pulse trains, adapted to drive respective stepper motors, for effecting motion of said source and receptor, said pulse trains having a predetermined mathematical relationship dependent upon the desired fulcrum height of the tomographic section to be produced; and applying said first and second pulse trains to the respective stepper motors for a predetermined number of pulse counts to effect motion with respect to said respective reference positions and effecting a tomographic sweep thereby.
