<p>A Hall Effect Imaging (HEI) electrode array and an ultrasound array are configured and controlled to provide rapid image acquisition with high contrast and definition. The electrode/ultrasound array, which in implementing HEI is used for imaging an object to which a magnetic field is applied, includes an electrode array comprising a plurality of electrodes (1-8) arranged to apply electrical signals along a plurality of directions which are non-parallel to each other and non-parallel to the magnetic field. The electrode/ultrasound array also includes an ultrasound sensor array comprising a plurality of ultrasound sensors (14) arranged to concurrently detect ultrasound signals resulting from excitation by electrical signals applied to the object by the electrode array. Preferably, the ultrasound sensors (14) concurrently detect ultrasound signals propagating in different directions. The electrical signals may be applied in different directions concurrently, the different electrical signals applied concurrently in different directions having different frequency spectra.</p> |
