A heart CT image processing method and apparatus and a non-transitory computer readable storage medium are provided in this application. The heart CT image processing method comprises reconstructing a heart CT image of a detected object based on projection data of a heart region of the detected object； processing voxel points having voxel values within a first threshold range in the heart CT image and obtaining a first image, wherein the first threshold range is defined by a CT value of a metal object； performing lung region segmentation on the first image to obtain a second image； performing initial heart region segmentation on the second image to obtain a third image； and performing rib removal on the third image to obtain a heart image.
