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.

摘要： An image processing method for interventional imaging in which a region of interest of a patient is viewed. The method comprises acquiring a succession of images of a region of interest of the patient. The method also comprises detecting and tracking, on the successive images, at least one surgical instrument introduced inside the region of interest of the patient, in order to isolate said instrument therein; and comparing two successive images on which the surgical instrument has been isolated in order to identify at least one common shape therein. The method further comprises estimating the displacement of said common shape between both of these successive images; and re-alignment processing of the different successive images depending on the thereby determined estimations of displacements, these displacement estimations being considered as corresponding to the displacement caused by the physiological movement of the patient with the exception of any other movement.
