ABSTRACT:
In an image reconstruction method for computed tomography the reconstruction of an image from datasets is accelerated so that, with adequate image quality, dynamic studies of moving organs or monitoring of moving therapeutic instruments are possible. To this end, data segments for a sub-scan reconstruction are taken from the continuously measured and pre-processed data stream. The starting angle of the individual data segments is not restricted to a fixed grid. The grid can be arbitrarily defined according to the current computing capability of the reconstruction computer.
