Surface Coils

Surface Coils for High-Field MRI

1H or Dual Frequency Surface Coils

Standard surface coils,
a tuning screwdriver and
a Remote Coil Matching Network .

Hundreds of standard coils,
1H or Dual Frequency,
Numerically optimized — Up to 50% higher S/N.

Curved Surface Coils also available

Standard coil diameters currently include
8, 12, 16, 20, and 24 mm.
Click on the desired frequency below to download a list of standard surface coils. The list includes size, frequency, sensitivity, detuning option, and part number. These standard products include single or dual frequency, transmit-receive (T), passive detuning (P), active detuning (A), 1H, 19F, 31P, and 13C for the following 1H frequencies:

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. Scroll down for description, part numbers and prices.
Delivery is usually 4-6 weeks for standard single tuned coils and 6-9 weeks for standard dual frequency coils.
Other sizes or frequencies are available on special order at higher prices and longer delivery time.

Features of Doty 1H or Dual Frequency Surface Coils

  • Featuring conductor geometries optimized for the best sensitivity and B1 homogeneity with biological samples.
  • Non-magnetic sealed tuning capacitors mounted adjacent to the coil on a low-loss dielectric substrate – either polyimide or teflon.
  • Balanced and designed for use with 50 Ω systems.
  • Fitted with double-shielded flexible rf line (Teflon or polyethylene) with BNC connector.
  • Passive or Active Detuning options for homonuclear experiments using a volume transmit coil
