Method for producing temporal sequence of tomographic images to pre-determined phase position of cyclic moving object, for use with tomography equipment, involves capturing projections of z-positions in arranged sequence

摘要

The method involves capturing projections of z-positions (z1,z2) in an arranged sequence. The z-positions are selected in a manner that the captured projections of neighboring z-positions are overlapped or adjacent to each other. A repeated control of the z-positions is provided for the projections to produce temporal sequence of images (1). A real time or reconstruction downstream of images is formed on the basis of obtained data of a temporal sequence of images. Two rotatably arranged imaging systems (4,5) collect covered projections around z-axis (3) of a tomography equipment (2).
