1. A method for performing a medical imaging study comprising: acquiring a preliminary scan; automatically detecting a set of local feature candidates from the preliminary scan; assessing the accuracy of each local feature candidate using multiple combinations of the other local feature candidates and removing a local feature candidate that is assessed to have the lowest accuracy; repeating the assessing and removing step until only a predetermined number of local feature candidates remain; locating a region of interest (ROT) from within the preliminary scan based on the remaining predetermined number of local feature candidates; and performing a medical imaging study based on the location of the ROI within the preliminary scan.
