Abstract

In this study, Magneto-Acousto Electrical Tomography with magnetic measurements technique is investigated using two dimensional (2D) simplified numerical breast model. This technique comprises of the electrical current induction and ultrasound in the static magnetic field. 2D numerical simplified breast geometry is modeled with an ultrasonic transducer (linear phased array (LPA)) placed on the top side of the simplified breast model. A rectangular loop coil is encircled the breast. The sensitivity matrix is obtained for this transducer-coil configuration. LPA transducer is steered with eleven angles (−25 ° to 25 ° at intervals of 5 °). The characteristics of this modality is shown by the singular value decomposition (SVD) method. The reconstruction of the images is performed by truncated SVD approach. This study shows that perturbations (5 mm × 5 mm) up to a depth of 3 cm can be detected.
