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.
