摘要： The present application is a detection system for locating and characterizing an object placed in a detection area in a three dimensional space. The detection system includes a plurality of magnetic field generators and magnetic field detectors arranged on opposite sides of the detection area and a control system for enabling generation of a magnetic field in the detection area by the magnetic field generators and for measuring of the magnetic field modified by the object at each of the magnetic field detectors. The detection system also includes a processor for processing the measured magnetic field to obtain a data set characterizing the object and a location of the object. The processor applies a reconstruction process on a predefined number of measurements of the modified magnetic field.

摘要： The present application is directed toward the generation of three dimensional images in a tomography system having X-ray sources offset from detectors, in particular in a system where the sources are located on a plane, while detectors are located on multiple parallel planes, parallel to the plane of sources and all the planes of detectors lie on one side of the plane of sources. A controller operates to rebin detected X-rays onto a non-flat surface, perform two dimensional reconstruction on the surface, and generate the three dimensional image from reconstructed images on the plurality of surfaces.
