Take a loop of wire shaped like a circle and apply a voltage potential to the ends of the wire and we produce a current through the wire. The electrons, flowing in a circle, create a magnetic field which extends out of the circle, the most basic electromagnet. If we loop many turns of wire we multiply the strength of our magnetic field.

If we make two such electromagnets and orient them on the same axis, we produce a vector addition of magnetic fields. Essentially, we end up with an X, where each line is a separate electromagnet. Because the fields add by vector addition, when we adjust the voltage applied to our loops of wire, we can point the magnetic field to any point within the angle of the X, extending out through the matter in front of it.


At infinity, the furthest point from the electromagnet, a magnetic field decreases quicker than the usual 1/d, we may refer to this area as the 'infinity point'. We arrange 8, or 16, 32 or so, equidistant magnetic X shaped transmitters around the circumference of a perfect circle thus pointing multiple magnetic fields at the same point at the same time. Each transmitter is thus capable of aiming its magnetic fields at all the points within a certain circle in the center of our scanning area.

Let us, for the sake of explanation, focus all our magnetic fields at the center spot. For this, each coil of wire will be driven with the exact same voltage, and current. At the furthest point, the center, the magnetic fields decay quicker than normal, and all of our infinity points collide. Due to the nature of magnetic fields adding by vector addition, the geometry of the system cancels out all the extraneous magnetic fields in the intervening matter. The resultant field strength, of all our transmitters combined, has thus concentrated the magnetic field energy upon the central spot. We have created a rod of magnetic energy at a distant point in 3-dimensional space.

If each transmitter is wrapped with a coil, and each of these receiving coils is connected in parallel, the receiving coils will sense the magnetic field strength as determined by the distant point. The 'permeability' of the atoms, chemicals, or neurotransmitters, which our magnetic infinity point resides in, will determine the magnitude of the output field.


Finally, we need to move our rod of magnetic energy through space in order to create television like video images. Each transmitter has 2 transmitting coils, so each one must be driven by 2 amplified 'video waveforms'. Each waveform is created such that all transmitter pairs point at the same point at the same time. Conceptually, this can be hard to envision, but the process is simple. Like a television, we choose to scan in a raster fashion, from left to right, one line at a time. The angle from each transmitter to the moving spot is calculated and the appropriate vector sum is stored in video memory. Each waveform, for every transmitter, is output, through high current amplifiers, simultaneously; thus moving our magnetic rod of energy through space in realtime, at television like frequencies.

Every element, from electric metals to sodium and potassium, have a different magnetic field permeability. The resulting video frequency output will display high resolution images of the bodies electromagnetic structure in realtime.

Essentially, we require a minimum of 8 transmitter pairs, 16 digital to analog channels, which are driven concurrently through high current amplifiers.

If we think of the system in terms of a block diagram, we can greatly reduce the size and complexity of our system. For each 'transmitter block', 1 of 8, 16 or 32, can be thought of as dual video memory, a counter to cycle through the memory, and finally dual digital to analog convertors connected to the dual coil transmitters. Readily available video memory, d/a convertors and CRT high current amplifiers can be employed to engineer our scanner. Clock each 'board' from a single horizontal and vertical sync signal and we can output, concurrently, the massive amount of digital data required for above defined system.

The vector mathematics, amplifier schematics, coil requirements and atomic permeablity equations are all available with all required details at the following url, along with pictures of the actual prototype scanner:
