MAGNETIC INDUCTION TOMOGRAPHY ILLUSTRATION

The principle of induction tomography

The coil system of induction tomograph

The principle of induction tomography. The tube of magnetic lines as analog of beam in classic tomography
 

The coil system of induction tomograph. 1 - inductors and detectors, 2 - screen
 

Experimental measuring system for magnetic induction tomography with 16 inductors and detectors (25463 bytes)

Image reconstructed from the data measured with the system (6530 bytes)

Experimental measuring system for magnetic induction tomography with 16 inductors and detectors. The bottle filled with saline solution inside the system is used as test object
 

Image reconstructed from the data measured with the system. The dark spot corresponds to the test object (plastic bottle 10 cm in diameter filled with 5% saline). The outward circle is drawn with diameter on which the coils are placed
 

Configuration of the complex phantom

Reconstructed image

Configuration of the complex phantom (percentage is the saline concentrations)
 

Reconstructed image (reference data set used for reconstruction was measured with the large tank without inner cylinders)
 

Initial conductivity distribution, which was used for simulation of measurements

Image reconstructed from the simulated results of measurement for 32-coil magnetic induction tomography system

Initial conductivity distribution, which was used for simulation of measurements. Lightest areas correspond to highest resistivity, the spots approximate some organs inside human chest (1 - muscles, 2 - spine, 3 - lungs, 4 - heart)

Human head cross-section: one of the first in-vivo images

   

 

Human head cross-section: one of the first in-vivo images. Two bright spots in the central part may be identified as ventricles of the brain filled with CSF.
