Paper Abstract

We present a method to automate acquisition of MR brain scans to allow consistent alignment of diagnostic images for patient follow-up, and to depict standardized anatomy for all patients. The algorithm takes as input a low-resolution acquisition that depicts the patient position within the scanner. The mid-sagittal plane dividing the brain hemispheres is automatically detected, as are bony landmarks at the front and back of the skull. The orientation and position of a subsequent diagnostic, high resolution scan is then aligned based on these landmarks. The method was tested on 91 data sets, and was completely successful in 93.4% of cases, performed acceptably in 4.4% of cases, and failed for 1.1%. We conclude that the method is suitable for clinical use and should prove valuable for improving consistency of acquisitions.
