An apparatus for collecting super-sampled imaging data includes an imaging scanner, a bed, and a first motor. The imaging scanner includes a plurality of detectors arranged substantially circumferentially about a scanner axis. The bed has a plane and a central axis that is generally in the plane of the bed. However, the bed is oriented so as to form a first non-zero degree angle between the central axis and the scanner axis. The first motor translates the bed along the central axis, and a second motor may translate the bed along an axis orthogonal to the central axis and scanner axis. Since the voxels pass through the scanner in different relative positions of the bed, additional information may be acquired during the scan.

Automated Positioning of a Patient Table Relative to a Medical Installation

Номер: US20160073979A1
Автор: Christoph Braun, Johann Uebler
Принадлежит: Individual

Embodiments are described herein for determining anatomical landmarks on a patient by virtue of anatomical landmarks being called up from a database with an anatomical model and being converted into individual body dimensions and an individual position of the patient. As a result, anatomical landmarks may be called up from a database, calculated individually for the patient and used as an item of reference location information. The positioning of the patient table is thus considerably accelerated, wherein the accuracy is also improved. Thus, the item of reference location information may be calculated individually for the same patient in a different position or a different patient with different body dimensions by virtue of this item of reference location information being recalculated by the conversion rule for the respective patient.

X-ray system for the iterative determination of an optimal coordinate transformation between overlapping volumes that have been reconstructed from volume data sets of discretely scanned object areas

Номер: US20200302660A1
Автор: Klaus Hörndler, Thomas Konig
Принадлежит: Ziehm Imaging GmbH

This disclosure relates to an X-ray system for obtaining referencing information in the form of a coordinate transformation between a first volume and a second volume, with the volumes partially overlapping. In this case two partially overlapping subareas of an extended object having a continuous distribution of a physical size are discretely sampled with a measuring apparatus; the volumes are reconstructed and the overlapping volumes are iteratively changed, wherein a bandpass filter is applied to the overlapping volumes, where said bandpass filter changes the Fourier domain representation of the overlapping volumes. The filtered overlapping volumes, in which the artifacts, induced by the discrete sampling, are matched, are compared by means of a measure of similarity, which is iteratively maximized by means of mathematical optimization. The coordinate transformation with the maximum result for the measure of similarity is used as the optimal coordinate transformation for combining the two volumes in the correct position. One application is the combination of 3D X-ray volumes that have been reconstructed by means of a cone beam computed tomography scanner, preferably a 3D C-arm.
