[Use of a homomorphic filter in combination with surface coils in MR tomography]

A new method for correcting the signal intensity from surface coil (homomorphic filters) was evaluated in 40 examinations. With this filter it is possible to compensate for signal loss when using surface coils for deep tissues and to avoid excessive signals from the surface. The method does not, however, provide any additional information. Properly used, there were no false positive findings, nor was there any loss of abnormal findings. The use of homomorphic filters is therefore safe and sensible.
