  • Patent number: 9135704
    Abstract: It is described a method for spatially characterizing a device positioned within an object, e.g. a patient's body, under examination that e.g. allows a clinician to easily assess the deployment state and position of the device. The method comprises the steps of acquiring (26) a set of images of the device, reconstructing (28) a three-dimensional model of the device from the set of images, comparing (30) the model of the device with an ideal model of the device in a predetermined deployment state inside the object and displaying (36) the model of the device on a display unit. For optical indication deviation areas of the deployed device relative to an ideal model of the deployed device can be determined and color-coded depending on the strength of deviation.

  • Patent number: 8463014
    Abstract: A method for determining an optimal trajectory for 3-dimensional rotational X-ray coronary angiography for a C-arm X-ray system that has at least two degrees of freedom, where the C-arm X-ray system is defined by a rotational movement of the C-arm expressed in a left/right coronary artery oblique angle, and a roll motion of the C-arm expressed in a caudal/cranial angle. The method includes generating of a 3-dimensional representation of a center-line of a body vessel in a region of interest. generating at least one optimal view map. Further, an optimal trajectory for the X-ray system within the optimal view map is determined, where an optimal trajectory is at least determined by movements of the C-arm within its two degrees of freedom allowing image projections with minimal foreshortening and/or overlap while minimizing an exposure to X-rays.

  • Publication number: 20100014740
    Abstract: It is described a method for determining an optimal trajectory (25) for 3-dimensional rotational X-ray coronary angiography for a C-arm X-ray system. The C-arm X-ray system has at least two degrees of freedom. They are defined by a rotational movement of the C-arm (11) expressed in a left/right coronary artery oblique angle, and a roll motion of the C-arm (11) expressed in a caudal/cranial angle. The method performs the following steps in a sequence. Firstly, a generation of a 3-dimensional representation of a centre-line of a body vessel in a region of interest is performed. Secondly, at least one optimal view map is generated. Finally, an optimal trajectory (25) for the X-ray system within the optimal view map is determined, wherein an optimal trajectory (25) is at least determined by movements of the C-arm within its two degrees of freedom allowing image projections with minimal foreshortening and/or overlap while minimizing an exposure to X-rays.

  • Patent number: 7113623
    Abstract: Methods and systems for reconstruction of a three-dimensional representation of a moving arterial tree structure from a pair of sequences of time varying two-dimensional images thereof and for analysis of the reconstructed representation. In one aspect of the invention, a pair of time varying arteriographic image sequences are used to reconstruct a three-dimensional representation of the vascular tree structure as it moves through a cardiac cycle. The arteriographic image sequences maybe obtained from a biplane imaging system or from two sequences of images using a single plane imaging system. Another aspect of the invention then applies analysis methods and systems utilizing the three-dimensional representation to analyze various kinematic and deformation measures of the moving vascular structure. Analysis results may be presented to the user using color coded indicia to identify various kinematic and deformation measures of the vascular tree.

  • Patent number: 5896859
    Abstract: A transfer belt including an adjustable waist belt and a harness strap, both of which are constructed of a pliant material. In one embodiment, the adjustable waist belt includes a first end terminating in a belt buckle having a slot through which a second end of the adjustable waist belt is extended. The harness strap of the belt is affixed proximal the first and second end of the waist belt. In other embodiments, a length adjuster is provided, handles may be positioned at the rear of the belt, and/or the belt buckle may be located to one side, beyond the front of the belt portion connecting the ends of the harness. To ensure correct placement of the transfer belt on a wearer, the outer surface of the waist belt and the harness strap are of one uniform color, while the inner surface of the waist belt and harness strap are of another uniform color. The harness strap is fitted by the user below the wearer's gluteals, and the adjustable waist belt is tightly secured by the user around the wearer's waist.
