    摘要: An image data processor automatically identifies individual picture elements representing embolic material in first and second 2D X-ray images in response to a luminance intensity value of the picture elements exceeding a threshold. The image data processor also automatically identifies individual volume elements in a 3D X-ray image dataset corresponding to the identified individual picture elements by, for an individual picture element, detecting intersection of a projected line with one or more volume elements in the 3D image dataset representing vessels. The projected line substantially passes from the individual picture element to an X-ray radiation source. The display processor initiates generation of data representing a display image showing the identified individual volume elements representing embolic material, with enhanced visualization.
