Magnetic induction tomography(MIT) is a noninvasive and contactless medical imaging technique. The 16 channels of MIT system is showed in the paper, which image for the low conductivity object with working at 1MHz. In the study, we use the water tanker filled with salt solution and the different conductivity agar blocks to simulate the human brain with edema or hematoma. The each sensor is composed...
Magnetic induction tomography is a new functional imaging technology. The eddy current analysis is the basic problem of the magnetic induction tomography forward problem. The eddy current distribution in a 2-D circle region was calculated in this paper. The expression of eddy current is composed of magnetic vector potential and scalar potential functions. The magnetic vector potential was calculated...
An magnetic induction tomography (MIT) hardware system is introduced in this paper. The system is composed of nine parts: signal source, sensor coils, preamplifier, canceling circuit, difference circuit, lock-in amplifier and the controller. One-dimensional measurement has been made, the relation between the phase variety and the conductivity of sample was constructed. A rectangular water-tank was...
