Abstract :
The needs of accurate information from tomography images has led to the exploration of 3D imaging which attracts both medical field and industrial process as 3D imaging technique provides additional info compared to 2D. The same thing goes to Magnetic Induction Tomography (MIT) even 3D is still new to this modality. The challenge of 3D scheme to MIT is that the sensitivity at the boundary is more pronounce compared the centre of region of interest (ROI). The introduction of tri-coil sensor jig offers solution to this issue as three layers of sensors are located in this design, with excitation coils arranged at the middle layer. This arrangement strengthened the sensitivity at the centre of the z-axis between upper and lower layer through the existing of middle layer. This paper would like to discuss on the sensitivity of the z-axis of tri-coil sensor jig from the scope of metal imaging application. The simulation result has found that all the three coils are sensitive to the metal object at different z-positions. This result provides additional info as it will be integrated in the 3D image reconstruction algorithm process for providing accurate location of the 3D reconstructed images.
