Abstract
A region-of-interest extraction method and an apparatus, and a device, a system and a storage medium are provided. The region-of-interest extraction method is applied to an X-ray imaging system. The X-ray imaging system includes a detector and an array X-ray source, the array X-ray source includes a plurality of X-ray sources having different projection angles, and imaging regions corresponding to the plurality of X-ray sources are formed on the detector. The method includes: acquiring geometric position parameters corresponding to the plurality of X-ray sources; grouping the plurality of X-ray sources according to the geometric position parameters of the plurality of X-ray sources, determining at least one X-ray source group, and imaging regions of X-ray sources in the same X-ray source group not overlapping with each other; combining the imaging regions of the X-ray sources in each of the at least one X-ray source group, so as to determine a combined imaging region corresponding to each of the at least one X-ray source group; and performing region-of-interest extraction on projection data in the combined imaging region corresponding to each of the at least one X-ray source group.
