    摘要: An optical guidewire system employs an optical guidewire (10), an optical guidewire controller (12), a guide interface (13) and an optical connector (15). The optical guidewire (10) is for advancing a catheter (20) to a target region relative to a distal end of the optical guidewire (10), wherein the optical guidewire (10) includes one or more guidewire fiber cores (11) for generating an encoded optical signal (16) indicative of a shape of the optical guidewire (10). The optical guidewire controller (12) is responsive to the encoded optical signal (16) for reconstructing the shape of the optical guidewire (10). The guidewire interface (13) includes one or more interface fiber core(s) (14) optically coupled to the optical guidewire controller (12). The optical connector (15) facilitates a connection, disconnection and reconnection of the optical guidewire (10) to the guidewire interface (13) that enables a backloading the catheter (20) on the optical guidewire (10).

    摘要: System and method for enabling intra-operative selection of an image registration transformation for use in displaying a first image dataset and a second image dataset in correspondence with one another. Image dataset acquisition devices (12, 14) obtain the first and second image datasets. A similarity function indicative of a likelihood that the first and second image datasets are in correspondence with one another is computed by a processor (16) and then a ranking of each of a plurality of local maxima of the similarity function is determined. Registration transformations derived from a plurality of the local maxima are displayed on a display (18), and using a user-interface (22), a physician can select each registration transformation to ascertain visually whether it is the clinically-optimal registration transformation for subsequent use.

    摘要: It is described a method for acquiring a series of two-dimensional X-ray attenuation data of an object under examination (310) by means of an X-ray imaging apparatus (100) having a rotatable scanning unit (301). In order to increase the angular range of the scanning unit (301), when a region of interest (HOa) located not in the center of the object (310) is examined the object under examination (310) is shifted such that the region of interest is temporarily positioned outside the center of rotation. By coupling the rotational movement of the scanning unit (301) with the translative movement of the object (310) in a synchronized manner a collision between the scanning unit (301) and the object (310) can be effectively avoided. By employing an automated motorized object table (312) a precise pre-determined movement of the object (310) can be achieved during the data acquisition. By using an appropriate phantom based calibration procedure carried out with the same table movements known three-dimensional reconstruction algorithm can be directly applied in order to generate a three-dimensional representation of the region of interest (110a).
