1. A computer-implemented process for detecting acquisition errors in a medical image, comprising: using a computer to perform the following process actions: generating a set of base images from a larger group of source medical images belonging to a same category as a medical image being screened for acquisition errors, wherein the base image set substantially captures the variance exhibited amongst the group of source images; for each of a group of medical images in the same category as those used to generate the base image set, computing a measure of a difference between the medical image from said group of medical images in the same category as those used to generate the base image set, and the base images in the generated set; establishing an acceptable difference between the base images in the generated set and a medical image associated with the same category as those used to generate the base image set, using the computed difference measures; computing a measure of a difference between the medical image being screened for acquisition errors and the base images in the generated set; determining if the difference measure computed for the image being screened for acquisition errors falls within the established acceptable difference; and whenever the difference measure computed for the image being screened for acquisition errors does not fall within the established acceptable difference, issuing an alert that the image being screened for acquisition errors contains an acquisition error.
