Abstract
System for live 3D x-ray viewing comprising an x-ray source, an x-ray detector, a processing unit, a monitor and means for detecting viewer's eyes, wherein the x-ray source and the x-ray detector are arranged at a movable C-arm. The x-ray source comprises two focal spots, wherein a separation of the two focal spots is adjustable so that the image acquisition angle between the two focal spots matches the viewing angle between the two eyes.
Claims17
A system for live 3D x-ray viewing, the system comprising:
- an x-ray source,
- an x-ray detector,
- a processing unit,
- a monitor and
- a position detector that detects a position of eyes of a viewer and determines the distance between the monitor and the eyes of the viewer, wherein:
- the x-ray source and the x-ray detector are arranged on a C-arm,
- the x-ray source comprises two focal spots,
- a separation of the two focal spots is adjustable,
- the processing unit is adapted to calculate the separation of the two focal spots on the basis of the distance between an object of interest and the focal spots, the distance between the monitor and the eyes of the viewer, and the distance between the eyes of the viewer, and
- the processing unit is adapted to provide a command for adjusting the separation of the two focal spots corresponding to the calculated separation.

A method for live 3D x-ray viewing, the method comprising:
- calculating the separation of two focal spots of an x-ray source, on the basis of the distance between an object of interest and the focal spots, the distance between a monitor and eyes of a viewer, and the distance between the eyes of the viewer,
- adjusting the separation according to the calculated separation,
- generating an x-ray image on the basis of radiation from one of the two focal spots,
- generating an x-ray image on the basis of radiation from the other one of the two focal spots,
- visualizing both images simultaneously on a monitor.
