Magnetic resonance-based quantitative imaging of the electric properties at radiofrequency without phase information.CP4

Electric properties tomography of human bodies from measurements performed by magnetic resonance imaging (MRI) is an innovative research field emerged in last years and denoted as MREPT. The accuracy of most MREPT approaches proposed in literature suffers from the impossibility of measuring the phase of the MRI transmit coil sensitivity. A variation of the contrast source inversion technique for MREPT, specifically conceived to work without the phase information, will be described.
