1. A computer-readable storage medium comprising computer-readable program code stored thereon which, when interpreted by a computing apparatus, causes the computing apparatus to implement an image processing tool for processing a plurality of biological images arranged in a plurality of image series wherein certain biological images across different image series have a predefined correspondence with one another, the computer-readable program code comprising: computer-readable program code for causing the computing apparatus to be attentive to receipt of an indication of a selected biological image from the plurality of biological images and belonging to a first one of the image series; computer-readable program code for causing the computing apparatus to be attentive to receipt of an indication of a segmentation mask created based on the selected biological image; computer-readable program code for causing the computing apparatus to apply the segmentation mask to a second biological image from the plurality of biological images, the second biological image belonging to a second one of the image series that is different from the first one of the image series, the second biological image having a predefined correspondence with the selected biological image; and computer-readable program code for causing the computing apparatus to display the second biological image after application of the segmentation mask.
