摘要： A system to track movement of an object travelling through an imaged subject is provided. The system includes an imaging system to acquire a fluoroscopic image and operable to create a three-dimensional model of a region of interest of the imaged subject. A controller includes computer-readable program instructions representative of the steps of calculating a probability that an acquired image data is of the object on a per pixel basis in the fluoroscopic image, calculating a value of a blending coefficient per pixel of the fluoroscopic image dependent on the probability, adjusting the fluoroscopic image including multiplying the value of the blending coefficient with one of a greyscale value, a contrast value, and an intensity value for each pixel of the fluoroscopic image. The adjusted fluoroscopic image is combined with the three-dimensional model to create an output image illustrative of the object in spatial relation to the three-dimensional model.
