摘要： There is described a method for generating a 2-D image of a 3-D object represented by a volume data set comprising a multiplicity of data points each having an opacity value. A plurality of notional rays are cast through the 3-D object and for each ray, a ray path is divided into a plurality of base sampling intervals defined by data points on the path. If it is determined that a difference in opacity values across a base sampling interval can become greater than a pre-determined value, successively smaller sampling regions are generated within the base sampling interval until it is determined that a difference in opacity values across each generated smaller sampling interval in the base interval is less than the pre¬ determined threshold. Values indicative of an interaction between the ray and the 3-D object in the sampling intervals along the path are accumulated using a direct volume rendering procedure to determine a pixel value in the 2-D image.

摘要： The invention relates to a method (100) of adapting a geometric model to an image data comprising determining a first partial transformation for mapping a first part of the geometric model into the image data and a second partial transformation for mapping a second part of the geometric model into the image data. By determining the first partial transformation of the first part of the geometric model and the second partial transformation of the second part of the geometric model, the geometric model can assume more shapes and therefore can be more accurately adapted to an object comprised in the image data.

摘要： The invention relates to a method and a system for the simultaneous reconstruction of the three-dimensional vessel geometry and the flow characteristics in a vessel system. According to one realization of the method, vessel segments (41) of a parametric models are fitted to differently oriented X-ray projections (Pl, Pk, PN) of the vessel system that are generated during the passage of a bolus of contrast agent, wherein the fitting takes the imaged contrast agent dynamics and physiological a priori knowledge into account. In an alternative embodiment, the vessel geometry is reconstructed progressively along each vessel, wherein a new segment of a vessel is added based on the continuity of the vessel direction, vessel radius and reconstructed contrast agent dynamics.

摘要： The invention relates to a system and a method for the guidance of a catheter (20) with an electrode (21) in an electrophysiological procedure. A sequence of images (I1, ... Ik, ...) of the catheter (20) and of a resting reference catheter (30) is generated with an X-ray device (10) and stored together with the associated electrographic recordings from the electrodes (21, 31). A reference image (Ik) may then be selected from said sequence that corresponds to a desired electrographic pattern (Ek). In a next step, the positions (T, R) of the catheters (20, 30) are localized on the reference image (Ik), wherein the position (R) of the reference catheter (30) can be identified with the position of this catheter (30) on an actual image (I). Thus it is possible to determine on the actual image also a target position (T') for the catheter (20) that corresponds to the position (T) of this catheter (20) on the reference image (Ik). Said target position (T) may finally be indicated on a monitor (60) to assist the guidance of the catheter (20) to a desired location.

摘要： An apparatus determines an injection point for targeted drug delivery into a patient's body by injection of the drug into a vessel feeding a target area including a target. To provide the interventionalist with an objective and quantitative assessment of potential drug injection points instead of letting him rely on his subjective impression from the visual inspection of DSA sequences, a processor (4) includes an identification routine (41) for identification of a vessel tree topology of vessels feeding the target area, a flow determination routine (42) for determining the percentage of drug material delivered to said target after injection into different potential injection points in the vessel tree, a selection routine (43) for selecting as optimal injection point the potential injection point resulting in the highest percentage of drug delivery to the target.

摘要： The invention relates to an imaging apparatus for imaging an object. A geometric relation determination unit (10) determines a geometric relation between first and second images of the object, wherein a marker determination unit (14) determines corresponding marker locations in the first and second images and marker appearances based on the geometric relation such that the marker appearances of a first marker to be located at a first location in the first image and of a second marker to be located at a second corresponding location in the second image are indicative of the geometric relation. The images with the markers at the respective corresponding locations are shown on a display unit (16). Since the marker appearances are indicative of the geometric relation between the images, a comparative reviewing of the images can be facilitated, in particular, if they correspond to different viewing geometries.
