3D Image Reconstruction from Compton camera data

In this paper, we address analytically and numerically the inversion of the integral transform (cone or Compton transform) that maps a function on R to its integrals over conical surfaces. It arises in a variety of imaging techniques, e.g. in astronomy, optical imaging, and homeland security imaging, especially when the so called Compton cameras are involved. Several inversion formulas are deve...

Fast 3D image reconstruction for rotating slat collimated gamma cameras

As an alternative to the use of traditional parallel hole collimators, SPECT imaging can be performed using rotating slat collimators. A gain in image quality could be expected from the higher photon collection efficiency, however, the plane integral data measured by this type of collimator require a reconstruction to invert the three-dimensional (3D) Radon transform. The use of iterative metho...

Compton scattering sequence reconstruction algorithm for the liquid xenon gamma - ray imaging telescope ( LXeGRIT )

The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is a balloon born experiment sensitive to γ–rays in the energy band of 0.2–20 MeV. The main detector is a time projection chamber filled with high purity liquid xenon (LXeTPC), in which the three–dimensional location and energy deposit of individual γ–ray interactions are accurately measured in one homogeneous volume. To determine the γ–ray...

Three-Dimensional Object Reconstruction from Compton Scattered Gamma-Ray Data

A new imaging principle for object reconstruction is proposed in Single Photon Emission Computer Tomography (SPECT) which is widely used in nuclear medicine. The quality of SPECT images is largely affected by many adverse factors among which chiefly Compton scattering of gamma rays. Recently we have proposed to exploit Compton scattered radiation to generate new data necessary for object recons...

Compton Imaging of MeV Gamma-Rays with the Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT)

The Liquid Xenon Gamma-Ray Imaging Telescope (LXeGRIT) is the first realization of a liquid xenon time projection chamber for Compton imaging of MeV γ-ray sources in astrophysics. By measuring the energy deposit and the three spatial coordinates of individual γ-ray scattering points, the location of the source in the sky is inferred with Compton kinematics reconstruction. The angular resolution...
