Surface
Coils for High-Field MRI/NMR
Numerically
optimized surface coils
Up
to 50% higher S/N
- Doty
surface coils feature conductor geometries optimized for the best
sensitivity
and
B1 homogoneity
with biological samples.
- Non-magnetic
sealed tuning capacitors mounted
adjacent to the coil on a low-
loss dielectric substrate – either
polyimide or teflon.
- Fitted
with double-shielded flexible rf line (Teflon or polyethylene)
with BNC
connector.
- Passive
or Active Detuning for homonuclear
experiments using
a volume transmit coil.
-
Double-tuned surface coils are also available.
- Coils will be covered
unless ordered as uncovered.
- A Remote Coil Matching Network (RCMN)
is required for use with the surface coils.
The RCMN (which
functions over a range of frequencies) can often be used for
several coils. See description
below.
Standard
coil diameters currently include 8, 12, 16, and 24 mm.
Other
sizes are available on special order. Please specify type, diameter,
frequencies,
and dielectric materials. Balanced circuits are used except for small
coils at low frequencies. The prices shown are typical for fd (frequency
x diameter) of 7 MHz*m or less, as for example, 24 mm @ 300 MHz.
For fd greater than 7 or for non-standard sizes, prices are higher.
