This paper presents some of the imaging analysis techniques which are currently used to investigate COMPTEL 1.8 MeV gamma-ray line data. In the first part of this paper, an algorithm is presented which allows the accurate prediction of the background distribution at a specific line energy using measurements at adjacent energy intervals. The second part deals with the different image reconstruction methods which are applied to COMPTEL data, namely the maximum entropy method, the Richardson-Lucy algorithm and Pixon- based image reconstruction. We conclude that after 5 years of experience with COMPTEL, 1.8 MeV gamma-ray line imaging techniques are well established allowing a comprehensive study of cosmic gamma-ray line emission.
