When used as receivers rf coils are responsible for detecting the mr signalthe oscillating net magnetic flux from the excited spin system can be captured by the coil in which an induced electric current is generated. Radiofrequency coils rf coils are the antennae of the mri system broadcasting the rf signal to the patient and or receiving the return signal rf coils can be receive only in which case the body coil is used as a transmitter or transmit an. Rf coils for mri will become an important resource forengineers technicians scientists and physicians wanting tosafely and successfully build or buy and use mr coils in thelaboratory of clinic similarly this handbook provides teachingmaterial for student fellows and residents wanting to betterunderstand the theory an operation of rf coils. Brukers mri cryoprobe uses cryogenic rf coils and preamplifiers cooled by a closed cycle refrigeration system this cooling procedure significantly improves the performance of the mri cryoprobe animal handling and supervision of the mri cryoprobe is very similar to standard room temperature rf coils
