A method for the detection and visualization of dynamic processes in an object volume

摘要

A method for the detection and visualization of dynamic processes in an object volume in which with a multilayer - computed tomography apparatus (1) a spiral scanning the size of the item being handled with a pitch p is carried out, which is selected so small that each layer of times the size of the item being handled in the case of the spiral scanning is detected, characterised in that from measured data of in each case two temporally successive turns, or half cycles by an additional calculation was part before or after an image reconstruction an image (23) is calculated and displayed the size of the item being handled so that from the image (23) a change within the size of the item being handled between the two temporally successive turns, or half cycles can be seen immediately, wherein a plurality of images (23) for different time phases δt & t_red/2 calculated and represented.
