PROBLEM TO BE SOLVED: To provide a method and a device for localizing a plurality of objects of interest in a CT image formation.SOLUTION: A spatial localization of an object of interest can be achieved using three sheets of projection images whose respective visual angle directions are approximately orthogonal to each other. In this method, locations of objects in a region of interest in a CT image can be quickly specified and the need of pre-reconstruction of the CT image can be eliminated, even in the case of the plurality of objects of interest exist in a scan visual field, and in the algorithm, a repetition step is not needed so that the method is quick and effective so as to be favorably applied to the application to a process. |
