Description

Tomographic methods enable a three-dimensional imaging of complex structures and are widely used in medical applications but also for scientific use in numerous fields. We propose a new imaging method based on the tracking of charged particles in the GeV range traversing a sample under investigation. By measuring the distribution of the particles' deflection angles at the sample, an estimate on the projected material budget is extracted for a given 2D-cell in the sample. Illuminating the sample from various rotational angles allows for the 3D-reconstruction of the material budget via an inverse Radon transform. For the validation of the method, first measurements have been performed at the DESY Test Beam Facility, using a positron beam of several GeV and the DATURA Beam Telescope for high-precision particle tracking. The measurement was performed for homogeneous and inhomogeneous samples, providing calibration on the hand, and showing the feasibility and potential of this method on the other.
