Abstract: An x-ray imaging system and method of operation includes a gantry having an x-ray source and an x-ray detector alignable with the x-ray source, along with an image processing system operably connected to the gantry and including a processing unit for processing the x-ray image data from the detector to form x-ray images. The processing unit is configured to determine a position of at least two radiopaque markers located on an object within the anatomy of a patient, where the at least two radiopaque markers identify a proximal end of the object and a distal end of the object. The processing unit can then form one or more x-ray images of the object and the anatomy, and present at least two different indicators representing the radiopaque markers within the one or more x-ray images on the display to provide anatomical orientation information regarding the object within the patient anatomy.

Abstract: Systems and methods are provided for imaging coronary trees via registration of angiographic projections with computed tomographic data. In one example, a method for imaging a coronary artery of interest in a patient may include acquiring computed tomography (CT) imaging data depicting a coronary tree, acquiring a single angiographic projection of the coronary artery of interest, registering the single angiographic projection to the CT imaging data, and determining a fractional flow reserve (FFR) of the coronary artery of interest based on the single angiographic projection registered to the CT imaging data.

Abstract: A system for simulating bilateral injection of contrast agent into a patient is provided. The system includes an x-ray imaging device and a controller. The controller is operative to: acquire a first image set of a first blood vessel having contrast agent therein via the x-ray imaging device; acquire a second image set of a second blood vessel having contrast agent therein via the x-ray imaging device; and generate a third image set based at least in part on the first image set and the second image set. The third image set includes at least one composite image that depicts both the first blood vessel and the second blood vessel.

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: An image processing method applied by a medical imaging device is proposed, including at least one camera and at least one display screen on which is displayed a medical image showing a region of interest of a patient, the method being characterized in that the region of interest is determined by the following steps, the screen and the camera being laid out so as to be facing a practitioner simultaneously, acquisition by the camera of at least one tracking image containing the eyes of the practitioner, analysis of the tracking image so as to localize in the medical image at least one pixel of interest contemplated by the practitioner on the screen from the orientation of the eyes of the practitioner, processing the medical image so as to select the region of interest from the localized pixel of interest.

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.
