Selection Criteria for Magnetic Stimulating Coils

Large, or Small Coils – circular or figure of 8?

Large coils provide a high penetration depth, but are not

very focused. The small coils are more focused, but have a

relatively shallow penetration depth. Thus there is an inverse

relation between penetration depth and focus.The coils

come in many sizes and shapes. The two most commonly

used coils are the circular shaped coil and the butterfly

shaped coil also known as the “figure of 8” coil.

Circular or Parabolic Coils

When applying the circular or parabolic coil, the induced

current in the tissue occurs under the windings. A fairly large

area of body tissue will be stimulated.

The circular or parabolic coil may be positioned

conveniently over many parts of the body, and usually serves

well as a “general purpose coil”.

Butterfly Coils

The Butterfly coils are more focused in comparison with the

circular coils. The two windings are placed side-by-side or

overlapping, enabling the coil to stimulate structures with

focus right under its center. The butterfly coil is useful in

focused stimulation.

When the highest number of stimulations are required dy-

The cool unit in combination with the Cool-B65 coil are

the solution if a long duration and high stimulation output is

required.

MagVenture Cool-B65 coil.

Dynamic cooled coils – Coils with external cooling

Static cooled coils. To prevent fast overheating during use

we developed the static cooled F-series of coils. The fluid

absorbes dissipated energy thus enabling more stimulis.

MagVenture placebo coils are geometrical identical with the

corresponding normal coils.

Placebo coil are intended for blind testing and have consid-

erable lower magnetic fields than the normal coils.

MagVenture develops special coils for special purposes. Many

coils have been developed. Examples MRi-B88 for use in MR

scanners and the Twin Coil for Magnetic Seizure Therapy

(together with the special MagPro MST stimulator)

Besides our standard coils we manufactures custom designed

coils based on specifications from our customers.

General coil features.All coils are designed for use with Magpro R30, X100, R30

with option, X100 with option and R100.

Coils with build in power control in the coil handle and

trigger button in the handle can also be used with a MagPro

Compact. (coil C-100, C-B60, RT 120-II and MMC-140-II)

Coils without built in power control and trigger button

requires the coil converter when connected to a MagPro

Compact.
