Abstract: A method of processing images for interventional imaging, wherein a region of interest is visualized, is provided. The method comprises acquiring a series of 2D images of the region of interest in a patient during at least one respiratory phase, acquiring an electrocardiographic signal which is synchronized with the acquisition of the series of 2D images, processing the electrocardiographic signal to estimate at least one deformation phase of the region of interest induced by the patient's respiratory movement, and registering the different successive 2D images in relation to the estimated deformation phase.

Abstract: A method for tracking the position of a person in an environment, such as a medical room, relative to a medical device is presented. The method comprises identifying the position of a medical device in the environment, providing a mobile device in the vicinity of a person in the environment, the mobile device configured to follow movement of the person in the environment, and identifying the position of the mobile device in the environment by using at least one stationary device. Further, the method comprises using a processor to process data relating to the position of the mobile device in the environment to obtain an expected position of the person in the environment, data relating to the position of the medical device in the environment, and data relating the expected position of the person in the environment to obtain an expected relative position of the person with respect to the medical device.

Abstract: In the present invention, a method and associated system is provided that produces a new sequence of combined X-ray/fluoro images obtained in synchrony with intravascular dataset/images. This synchronization is based on the time tags recorded at the acquisition of one dataset of the X-ray/fluoroscopic images and the intravascular images/datasets and the cardiac cycle correspondence between the combined X-ray/fluoro datasets/images. The combined X-ray/fluoro and intravascular sensor images provided in the method for each position of intravascular measurement/slice along the blood vessel allows the physician the ability to determine the planned position of the treatment, e.g., a stent, in the X-ray/fluoro images based on the intravascular images, and allows an accurate assessment of the target/lesion location in the X-ray/fluoro images during treatment.

Abstract: Systems and methods of stent enhancement in medical images includes obtaining a plurality of medical images of a vessel and a stent. A centerline of the vessel is obtained in medical images of the plurality of medical images. A deformation field across the medical images of the plurality of medical images is estimated based at least in part upon the obtained centerlines. The medical images of the plurality of medical images are registered to a common reference image. The images are temporally integrated to obtain an enhanced visual representation of the stent.

Abstract: A method for enhancing the visualization of a plurality of objects within an imaged subject. The method includes acquiring a plurality of images of the plurality of objects disposed in the imaged subject and supported by a plurality of guide wires; generating a complex deformation field based at least in part on a plurality of landmarks disposed in the plurality of images; and generating a composite image based at least in part on the complex deformation field. The complex deformation field models deformation induced on the plurality of objects by at least two or more guide wires of the plurality.
