摘要： The present invention relates to simulated spatial live viewing of an object. In order to provide spatial information to the user with reduced requirements concerning to maintain a particular position e.g. with respect to a 3D display or to wear or activate additional components, such as 3D glasses, it is provided to generate an electron beam (38) from a cathode (32) arrangement towards a target area of an anode (34) and to control the electron beam such that the electron beam hits the anode at a moving focal spot (44), wherein the electron beam is controlled such that the focal spot moves at least in a first moving direction (46) transverse to a viewing direction (48). Thus, X-ray radiation (42) is generated by the electron beam impinging on the moving focal spot. Further, it is provided to detect X-ray radiation at least partially passing an object and to generate respective X-ray detection signals. Still further, monoscopic 2D images are generated based on the detection signals, which monoscopic 2D images relate to different view-points as defined by the moving focal spot. The monoscopic X-ray images are displayed from the different view-points.

摘要： 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.
摘要翻译： X射线管包括阴极，阳极和偏转装置。 阴极和阳极产生指向阳极的目标区域的电子束，以通过撞击目标区域的电子束的电子产生X射线辐射。 偏转装置控制电子束，使得电子在不同的焦点位置撞击阳极。 偏转装置提供逐步偏转以在单视角观看和立体观看之间的无级变换。 对于单视野观察，从单个焦点位置产生X射线辐射。 为了立体观看，X射线辐射是从横向于观察方向的第一立体声方向间隔开的两个焦斑位置产生的。 偏转装置为垂直于第一立体声方向和观察方向的第二立体声方向的立体焦点位置提供逐渐的偏转。

摘要： A scintillator layer (SL) for X-ray imaging including at least one scintillator element (SE) capable of converting X-radiation into light, the element having two faces, an ingress face (S1) for admitting X-radiation into the element (SE) and an egress face (S2) distal from the ingress face (S1), wherein the two faces (S1,S2) are arranged shifted relative to each other, so that a longitudinal (LAX) axis of the scintillator element (SE) is inclined relative to a normal ( n ) of the layer.

摘要： The present invention relates to a system for X-ray imaging. It is explained to position (210) an X-ray detector relative to an X-ray source such that at least a part of a region between the X-ray source and the X-ray detector is an examination region for accommodating an object. The X-ray source and X-ray detector are controlled (220) by a processing unit in order to: operate (230) in a first imaging operation mode; or operate (240) in a second imaging operation mode; or operate (250) in the first imaging mode and in the second imaging mode; or operate (260) in a third imaging operation mode. The detector comprises a first scintillator, a second scintillator, a first sensor array, and a second sensor array. The first sensor array is associated with the first scintillator. The first sensor array comprises an array of sensor elements configured to detect optical photons generated in the first scintillator. The second sensor array is associated with the second scintillator. The second sensor array comprises an array of sensor elements configured to detect optical photons generated in the second scintillator. The first scintillator is disposed over the second scintillator such that X-rays emitted from the X-ray source first encounter the first scintillator and then encounter the second scintillator. The first scintillator has a thickness equal to or greater than 0.6mm. The second scintillator has a thickness equal to or greater than 1.1mm. In the first imaging operation mode the first scintillator and the first sensor array are configured to provide data useable to generate a low energy X-ray image. In the second imaging operation mode the second scintillator and the second sensor array are configured to provide data useable to generate a high energy X-ray image. In the third imaging operation mode the first scintillator, the first sensor array, the second scintillator and the second sensor array are configured to provide data useable to generate a combined energy X-ray image.
