Embodiment Construction

[0044] figure 1 An X-ray imaging system 10 is shown for monoscopic and stereoscopic viewing. The X-ray imaging system 10 is provided with an X-ray source 12 , an X-ray detector 14 and a processing unit 16 . The X-ray source 12 and X-ray detector 14 are arranged on a C-arm structure 18, which is mounted to a movable support structure 20 that allows for surrounding an object of interest (e.g. , the patient) in which the object is only indicated with a circular structure (reference number 22). Further, a support structure (eg, patient table 24 ) is provided for supporting subject 22 . Furthermore, a display device 26 is shown, as well as an interface and control device 28 shown in the foreground.

[0045] The X-ray source 12 is an X-ray tube 30 as described in more detail below with reference to the following figures. The X-ray detector 14 is configured to provide the X-ray detection signal to the processing unit 16, and the processing unit 16 is configured to calculate monos...

Abstract

The present invention relates to monoscopic and stereoscopic X-rayviewing. In order to provide an improved fluent work flow for X-rayviewing with an improved visual perception of depth information, it is provided to generate an electron beam from a cathode arrangement towards a target area of an anode; to deflect the electron beam such that the electron beam hits the anode at different target spots (94a, 94b), wherein the variation is provided as gradual variation ofan impinging direction of the electrons such that a stepless transition between monoscopic and stereoscopic viewing is provided. In the monoscopic viewing, X-rayradiation is generated from a single focal spot position, and wherein in the stereoscopic viewing, X-rayradiation is generated from two focal spot positions spaced apart from each other in a first stereo-direction transverse to a viewing direction (92). It is further provided to generate X-rayradiation by the electron beam impinging on the target area, wherein the X-rayradiation is provided with different focal spots for monoscopic and stereoscopic X-rayimaging. Still further it is provided to display or otherwise provide image data of the object with a gradual transition between monoscopic and stereoscopic viewing.

Description

technical field [0001] The invention relates to an X-ray tube for monoscopic and stereoscopic observation, an X-ray imaging system for monoscopic and stereoscopic observation, a method for providing spatial observation of an object, a computer program module and computer readable media. Background technique [0002] In order to provide depth information of objects, for example X-ray stereo imaging is used in medical imaging. However, it has been found that although stereoscopic imaging provides useful depth information, users (eg, physicians) continue to use and sometimes even prefer monoscopic viewing techniques. Therefore, sometimes avoid switching to stereoscopic imaging. Therefore, sometimes the additional depth information is not made visible to the user. US2010 / 0067662 describes a stereoscopic rotating anode X-ray tube. Contents of the invention [0003] Therefore, there may be a need to provide an improved smooth workflow for X-ray observation with improved visu...
