摘要： A method for processing an image of a body region is provided, the region comprising a plurality of vessels capable of propagating a fluid of the body, the image comprising a plurality of pixels each being associated with an intensity. The method comprising determining, for each pixel, a probability that the pixel belongs to a vessel, based on the intensity of the pixel; simulating a propagation of the fluid from at least one source pixel towards the pixels of the image, the propagation being simulated to have a velocity that is function of the probability that the pixels of the image belong to a vessel; and inferring from the simulation a propagation time between the source pixel and each of the pixels of the image.

摘要： A system to navigate an image-guided object traveling in an area of interest of an imaged subject in relation to an acquired image of the imaged subject as created by an imaging system is provided. The system includes a navigation system to track movement of the object in the imaged subject in spatial relation to a navigation coordinate system, and a controller. The controller is operable in detecting an image of the object in the at least one image of the imaged subject, calculating a spatial relation between the location of the image of the object and a tracked location of the object, and modifying the spatial relation of the image coordinate system relative to the navigation coordinate system so as to reduce the difference between the location of the image of the object and the tracked location of the object by the navigation system.

摘要： A system for navigating an image-guided object through an imaged subject supported on table in relation to an image acquired by an image detector is provided. The system includes a first tracking element attached to the patient, and a second tracking element attached at the table. The first and second tracking elements define first and second coordinate systems. A controller is operable to register the second coordinate system with a third coordinate system defined by the image detector, measure a spatial relation between the first tracking element and the second tracking element, register the first coordinate system with the third local coordinate system defined by the image detector based on the spatial relation between the first and second tracking elements, and generating a composite image comprising a virtual image of the object in spatial relation to the image of the imaged subject acquired by the image detector.
