Accurate placement of a 2D plane across the aorta arch while examining scout images is a complex task that makes the operator’s workflow difficult when bolus tracking in DCE-MRI. We present a novel method for automated scan prescription for an oblique plane delineating the entire aortic arch used to monitor bolus arrival. The oblique plane was prescribed automatically by selecting the optimal oblique angle using regression forests. A dataset with 31 volunteers was tested, and all cases depicted the cross section of the aortic arch clearly. This automation will assist the operator and decrease the total examination time.
