Signal phase acquired via gradient recalled echo
MRI sequences provides and an important source of tissue contrast. The use of phased
array coils results in multiple-channel images that have to be combined to form
a single image. A robust method of computing phase images has been challenging
to develop, primarily due to the distribution of noise in phase images. We
propose a new approach of combining phase images by exploiting the inherent
noise in signal phase. Our selectively combined signal phase results show an
improvement in the quality of the combined phase image in comparison to
existing methods.
