DIRECT CONTROL OF X-RAY FOCAL SPOT MOVEMENT

摘要

The present invention relates to providing spatial information of a volume of interest of an object. In order to reduce complexity of a work flow in a hospital environment when X-ray imaging is used, an X-ray imaging system (10) for providing spatial information of a volume of interest (20) of an object is provided, wherein the system comprises an x-ray image acquisition unit (12), a display unit (14), an input unit (16), and adapting means (18). The x-ray image acquisition unit is configured to acquire a first image of a volume of interest of an object in a first projection direction and to acquire a second image in a second projection direction. Further, the display unit is adapted to display the first and the second image. In addition, the input unit is configured for a determination (22) of the second projection direction by an input of a user (24); wherein the user input comprises a change in a viewing-direction (15) of the user viewing the first image. Still further, the adapting means are configured to adapt a spatial relation between the projection direction of the image acquisition unit and the volume of interest of the object such that the projection direction correlates with the second viewing direction.

主权项

1) An X-ray imaging system for providing spatial information of a volume of interest of an object, comprising:
an X-ray image acquisition unit, a display unit, an input unit, and adapting means; wherein the X-ray image acquisition unit is configured to acquire a first image of a volume of interest of an object in a first projection direction and to acquire a second image in a second projection direction;wherein the image acquisition unit provides stereo image data and wherein the first image is a first stereo image and wherein the second image is a second stereo image;wherein the display unit is adapted to display the first and the second image;wherein the display unit comprises a first display configured to present the first stereo image and a second display configured to present the second stereo image;wherein the two displays are arranged in relation to a user's eyes such that the first and second stereo images are forming a common viewing direction towards a virtual point of focus;
wherein the input unit is configured for a determination of the second projection direction by an input of a user; wherein the user input comprises a change in a viewing-direction of the user viewing the first image; and wherein the adapting means are configured to adapt a spatial relation between the projection direction of the image acquisition unit and the volume of interest of the object such that the projection direction correlates with the second viewing direction.
