MULTI-CHANNEL METHOD AND DEVICE TO EVALUATE MAGNETIC RESONANCE SIGNALS, WITH REDUCED NUMBER OF CHANNELS
First Claim
1. A method to evaluate magnetic resonance signals comprising the steps of:
- generating first signals with coils in a magnetic resonance tomography apparatus by interaction of the coils with magnetic fields emanating from a defined region of a subject in the magnetic resonance tomography apparatus;
supplying said first signals to a processor and, in said processor, automatically calculating weighting factors from said first signals;
generating second signals with said coils by interaction of the coils with magnetic fields emanating from the region of the subject;
supplying said second signals to said processor and, in said processor, automatically calculating weighted signals by weighting said second signals with said weighting factors; and
making said weighted signals available at an output of said processor.

Abstract
An optimized processing of data of multiple local coils is enabled by a device and a method to evaluate signals received with coils of a magnetic resonance tomography apparatus, wherein first signals are generated by means of coils via magnetic fields coming from a body, wherein a region in the body is defined, wherein weighting factors are calculated with the use of the first signals, wherein second signals are generated with the coils from magnetic fields coming from a body, wherein signals weighted with the use of the weighting factors are calculated from the second signals, wherein the weighted signals are processed further.
