Abstract
In a method applied and an x-ray system for determining a spatial relationship of X-ray datasets measured independently of one another, an x-ray apparatus registers X-ray datasets of a patient and a scale is provided that makes position data available that are identifiable in at least one of the registered dataset. The position data serve for the determination of the spatial relationship between at least two X-ray datasets that were registered from different body portions of the patient.
Claims11
An x-ray system comprising:
- an x-ray apparatus for obtaining multiple x-ray datasets of a patient respectively from different body portions of said patient;
- and
- a scale disposed in fixed relationship to said patient, said scale containing scale indications that are visible in at least one of said x-ray datasets, for indicating a spatial relationship between at least two of said x-ray datasets obtained from different body portions of said patient.
An x-ray system comprising:
- an operating table adapted to receive a patient thereon, said operating table being selectively positionable;
- an x-ray apparatus for obtaining multiple x-ray datasets of said patient on said operating table respectively from different body portions of said patient, said respective x-ray datasets of said different body portions of said patient being obtained by selectively positioning said operating table;
- and
- a motion acquisition device for identifying motion of said operating table for determining a spatial relationship between at least two of said x-ray datasets obtained from said different body portions of said patient by quantitatively identifying movement of said operating table relative to said x-ray apparatus between respective exposures for obtaining said at least two x-ray datasets.
A method for determining a spatial relationship of x-ray datasets obtained independently of each other comprising the steps of:
- obtaining multiple x-ray datasets from a patient, respectively from different body regions of said patient;
- providing a scale in fixed relationship to said patient having scale indications thereon which are visible in at least one of said x-ray datasets;
- and
- determining a spatial relationship between at least two of said x-ray datasets respectively obtained from different body regions from said scale indications in said at least one of said x-ray datasets.
A method for determining a spatial relationship of x-ray datasets obtained independently of each other, comprising the steps of:
- disposing a patient on a selectively movable operating table;
- obtaining multiple x-ray datasets of said patient respectively from different body regions of said patient by irradiating a first body region with x-rays with said operating table positioned at a first position and moving said operating table to a second position and irradiating a second body portion of said patient;
- quantitatively measuring movement of said operating table between said first position and said second position;
- and
- identifying a spatial relationship between at least two of said x-ray datasets respectively obtained from said different body regions from said quantitative identification of said movement of said operating table.
