摘要：
A method comprising the steps of: receiving image data representing an imageprocessing the data to generateori-entation information processing the data using the orientationinformation to measure a quantity called local phase in a directionperpendicular to the orientation of a putative vessel using the phasemeasurements from three collinear image locations or fromtwo locations to detect the centreline of a symmetric image structure, such asa blood vessel, and to locate a centrepoint defined bythe intersection of the centreline with the line created by the measurementlocations.
