摘要：
A cryoprobe is disclosed comprising a probe shaft made of a low magnetic susceptibility material and an electrical resistance heater comprising counter-wound helical coils located within the probe shaft. The counter-wound helical coils are formed by a single wire counter- wound to form a first set of coils wound in a direction counter to a second set of coils, such that when current is supplied to the electrical resistance heater, a first magnetic field generated by the first set of coils is opposite to a second magnetic field generated by the second set of coils. The electrical resistance heater can heat, thaw, and/or cauterize tissue. The electrical resistance heater can be made of a low magnetic susceptibility material so as to resistively heat tissue concurrently during magnetic resonance imaging (MRI). A method of electrically heating a tissue in conjunction with MRI, and a method of imaging a cryoprobe using MRI is also disclosed.
