The invention provides a CT imaging method. The technical scheme is as follows: pre-reconstruction for an image is not carried out, an iteration step is not involved in the algorithm, a detected object is positioned by adopting projection drawings in multiple angles of view, and therefore, projection data can be rapidly and accurately repaired; on the basis, the data after the first-time repairing is further subjected to comparison repairing according to PET projection data, and then the comprehensive correction for the CT image is realized by combining with a filtering means and negative logarithm operation correction. According to the CT imaging method, the data correction operation in three angles is combined, the effects are remarkable, but the overall logic is not complex, therefore, no load is caused to the programming, and thus the CT imaging method has the outstanding popularization prospect.
