Background: Due to its imaging principle advantages and the development of detectors

nuclear electronics

Compton camera has once again put forward. Purpose: This study aims to build a Compton camera via Monte Carlo simulation and test its backprojection algorithm. Methods: By using Monte Carlo simulation software GEANT4

a Compton camera with stripes structure is designed and data for reconstruction image of source is read out. Backprojection imaging reconstruction algorithm is studied for getting the reconstruction of source. Results: Using backprojection algorithm and simulated Compton camera

when the distance between source and the scattering detector is 40 mm

the spatial resolution is FWHM=8.0 mm

angular resolution is 3° and γ photon imaging efficiency is 0.38%

which are better than most of the pinhole and coded aperture γ camera imaging. Conclusion: Because of the existence of large amount of data

Compton camera needs long calculation time for measuring data. The next step is improving simulated Compton camera to study its performance parameters

while the maximum likelihood algorithm could improve the spatial resolution of Compton camera. Abstract
