Abstract :
Three-dimensional-position-sensitive CdZnTe detectors have excellent energy resolution along with imaging capability. In this work, a 2 cm × 2 cm × 1.5 cm CdZnTe detector was used to detect shielding in front of sources. By using the energy-imaging integrated spectral deconvolution (EIID) algorithm, the shielding has a unique signature in the reconstructed image.
