We present a new method of the automatic scan prescription in MRI liver scans. 3D dataset acquired using fast T1 sequence is preprocessed and converted to 2D coronal projection images to avoid the need for complicated and time-consuming 3D segmentation. 2D Active Shape Model is applied to the projection image and the outer shape of the liver is extracted. The scan plane locations are identified from the inferior and superior edges of the outer shape. 38 volunteers and 15 patients data was tested and showed the satisfactory results in the position accuracy and the computation time.
