Automatic and Reproducible Positioning of Phase-Contrast MRI for the Quantification of Global Cerebral Blood Flow
Figure 4
Effects of the template on turning points detection.
Top panels show two left VA derivative templates and red stars show the turning points of the templates. Middle panels show the matching between the left VA derivative of a subject and the two templates. Red vertical lines show the rough regions of turning points which are determined by padding around the turning points of the templates. Bottom panels show the regions determined by matching with the templates. Red stars show the turning points detected and red triangles show the position of the scan plane.
