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...
Spinal cord stimulation (SCS) is a alternative treatment method for drug free treatment for chronic pain. Electrodes are placed to Spinal column's epidural tissue to blocked transfer of pain to brain and to stimulate dorsally column of pain. Today there are two two designs of electrode which are used in Spinal cord stimulation (SCS): a percutaneous (PERC) design, consisting of annular electrodes distributed...
Spinal cord stimulation (SCS) is a standard treatment method for drug free treatment for chronic pain. In this approach, an electrical current is applied to the region where the chronic pain signals reach the spinal cord and preventing pain sensation from reaching the brain, the pain sensation is been destroyed. To apply current to source of pain, two types of leads are used: percutaneous lead and...
Hall Effect Imaging (HEI) is a method used to image conductivity distribution of a biological body. HEI benefits from the interaction of ultrasound with a static magnetic field to generate velocity current density distribution inside the body. Due to the velocity current density, a resultant voltage is sensed by electrodes attached on surface of the body and used for reconstructing the conductivity...
In this study, the sensitivity matrix for contactless electrical conductivity imaging was analyzed. Images of conductivity distribution were obtained using the reconstruction algorithms. To analyze the sensitivity matrix, a homogeneous volume conductor with 0.2 S/m conductivity and a 7×7 grid of coil pairs were chosen. Sensitivity distributions for all receiver- transmitter coils were imaged. To image...
