Paper Abstract

As in MRI, orientation of the patient relative to field lines significantly impacts signal generated. Oblong inclusions generate far less thermoacoustic signal when oriented with long axis perpendicular to E field lines of radiofrequency excitation. We present simulated and low-power measured results below.
