Abstract
OBJECTIVE: Application of the backprojection image reconstruction algorithm in magnetic induction tomography for imaging of low contrast inclusions in conductive background is investigated. APPROACH: Both FDTD numerical simulation and experiments with the 16-channel measuring system and saline phantom are used. MAIN RESULTS: It is demonstrated that spatial redistribution of the sensitivity of measurements related with background conductivity does not affect the projection lines and keeps possibility of backprojection image reconstruction, which is important in biomedical applications of MIT. SIGNIFICANCE: The applicability of backprojection in biomedical MIT has been proved. The reconstruction algorithm is explained in detail.
