Transducer selection and application in magnetoacoustic tomography with magnetic induction
Y Zhou, J Wang, X Sun, Q Ma, D Zhang - Journal of applied physics, 2016 - pubs.aip.org
As an acoustic receiver, transducer plays a vital role in signal acquisition and image
reconstruction for magnetoacoustic tomography with magnetic induction (MAT-MI). In order
to optimize signal acquisition, the expressions of acoustic pressure detection and waveform
collection are theoretically studied based on the radiation theory of acoustic dipole and the
reception pattern of transducer. Pressure distributions are simulated for a cylindrical
phantom model using a planar piston transducer with different radii and bandwidths. The …
