Abstract	An approach for field and source 3D reconstruction visualizing the measured data of 2D magnetic field distributions is reported. A 3D volume of data for visualization of field is created from the 2D slices of locally measured and visualized field distribution at parallel surfaces by transforming each pixel in the 2D slice to its corresponding 3D location using the position, orientation and Green's function. The image of the locally measured field data are visualized and processed. The color source distribution which corresponds to the field source distribution is obtained using the image color model. This reconstruction approach is successfully applied in metallic tubes. The field distribution changes according to respective space locations, shapes, numbers and dimensions of existed defects and cracks in the tube.
