Image data based retrospective temporal selection of medical images

A method for ordering a plurality of images of a portion of a cardiovascular system comprising:

• receiving from an image scanner a plurality of images recorded over a period of time, the images representing one or more locations along the extent of the cardiovascular system;
• deriving a cardiac cycle signal from the plurality of scanned images;
• and
• assigning a phase in the cardiac cycle to each scanned image,
• wherein deriving the cardiac cycle signal comprises:
• segmenting a set of data representing a cross-section of the aorta in each image;
• computing an area value representing an area of the cross-section;
• and
• determining the cardiac cycle signal based on a sequence of the area values for each image.
