Surface
Coils for High-Field MRI/NMR
Numerically
optimized surface coils
Up
to 50% higher S/N
Not
all Surface Coils are Created Equal
- 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.
- Diode-clamped
versions are available for homonuclear
experiments using
a volume transmit coil.
-
Double-tuned surface coils are also available.
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.
