A Satisfied Customer - Perhaps the world is better Flat!

Magnetotron (Circa 1974)
Sometime ago I was reading a letter from a satisfied Curatron customer who had upgraded from an older technology PEMF machine called the Magnetotron. I was amazed to find out that this device may still be in production. There are and have been several machines over the years that require the user to sit inside a coil rather than on a simple flat pad or mattress. These arcane devices are difficult to use and tend to generate weak magnic fields.

Simple Coil Field Lines
The patient needs to be inside the cylinder, which is often a cumbersome process, especially for elderly people. The body cylinder was developed decades ago and was the only solution to generate sufficient magnetic field energy in order to be effective since the electronics available during the 80’s were unable to drive sufficient energy into surface coils. These types of cylinders have become obsolete and are still sold only in combination with obsolete PEMFT devices. “ You can read more at http://www.pemft.com/PEMF-coils.
The Curatron uses flat coils and is much easier to use. The computerization of various frequencies and the strength of the magnetic field is superior. The Curatron mattress/pad system has multiple coils embedded in the pad or mattress and all coils are triggered and in use at the same time providing a reasonably uniform pulsed electromagetic field over the entire region of the body being treated.
The older coil system such as that used by the Magnetotron coil generate localized fields inside the coil itself. Full body coverage without moving the coil is impossible.

Heavier folks find the coils to be difficult to get into and they can make one feel a little clausterophobic. Even MRI systems today are moving to Open MRI to reduce the feeling of being closed in and allow their systems to fit those wider folks who simply just don’t fit in the older MRI tunnels.

Modern Flat Coil Technology (Circa 2009) - Imagine up to 400 Gauss in a 20" x 28" pad.
The Curatron is also available with high energy pad about 20″ x 28″ that delivers a 300 Gauss (400 Gauss in the PC model) induction level. This is unparalleled performance and is not available with any other system on the market today.
The flux be with you! Where is that Magnetic Flux?
Many of the various models Curatron 2000 come with a mattress or therapy pad to deliver the magnetic flux to you, the user. The coils typically are arranged longitudinally in the mattress or pad. Some of our customers become concerned that all of the energy/flux density is in the center of the mattress or pad. Nothing could be farther than the truth.
I decided to check with the experts at the factory and I received this response.
“The magnetic field is spread evenly over the mattress as far as technological possible. The fact that you are only able to ‘feel’ with the test magnet the peaks in the fields closest to the area where the coils are located is because these areas do indeed create the highest power and will result in the highest mechanical vibrations in the test magnet.Having said this however placing of more coils closer together will result into opposite forces between the magnetic field lines cancelling out the resulting fields or placing coils farther apart will both lead to ‘dead’ magnetic areas. Also different coil diameters will not improve the aforesaid.
The strength of the magnetic field decreases as the square root of the difference while the angle used for the measurement is critical as well.
Please be assured that the energy entering the body when laying on the mattress is optimally spread throughout the body taking also into account the distance of the average body to the mattress, the angle and the highest body mass according to the location. The only exception is into the lower legs and feet somewhat for which we recommend to use the therapy pad.”
Let’s chat a little about how some of the other guys do it!
Some other manufacturers use only one large coil in their full body mat, which is actually a long wire surrounding the mat. No difficult mathematical formulas are needed to show that the electromagnetic field in such a mat is a complete joke: it is impossible to come close to an evenly spread magnetic energy field over the full surface of such a mat!
The electromagnetic field generators for all the Curatron systems (home and professional units) are designed to drive all the coils in the mats all at the same time during the complete therapy session. The coils in the mattress are placed in such a way that the magnetic field is evenly spread out, as far as this is mathematically possible.
