摘要： The invention describes a method of generating metabolic images of an investigation region (3) of a body (1) by irradiating an X-ray fluorescence marker in that region and detecting the resulting X-ray fluorescence with a fluorescence detector (30). A fan beam (12) is used as a source of primary X-radiation, thus allowing the scanning of a whole body slice (3) in one step. The fluorescence image may be directly measured, e.g. by mapping voxels (104) of the investigation region onto pixels (134) of the detector (130) with the help of a pinhole collimator (132), or it may be reconstructed by procedures of computed tomography. Moreover, a morphological image may be generated by simultaneously recording X-ray transmission through the body (1).
摘要翻译：本发明描述了通过在该区域中照射X射线荧光标记物并用荧光检测器（30）检测所得X射线荧光来产生身体（1）的调查区域（3）的代谢图像的方法。扇形光束（12）被用作初级X辐射源，从而允许在一个步骤中扫描全身切片（3）。可以直接测量荧光图像，例如。通过借助于针孔准直器（132）将调查区域的体素（104）映射到检测器（130）的像素（134）上，或者可以通过计算机断层摄影的程序来重构。此外，可以通过同时记录穿过身体（1）的X射线透射来产生形态学图像。

摘要： The invention relates to a computed tomography apparatus which includes a scanning unit which is rotatable, relative to an examination zone (13), around an axis of rotation (14) which extends through the examination zone (13), and also includes a radiation source (S) for generating a primary fan beam (41) which traverses the examination zone (13), and a two-dimensional detector array (D) which includes a plurality of detector elements and a part of the measuring surface of which detects primary radiation from the primary fan beam (41) whereas an other part of its measuring surface detects scattered radiation produced in the examination zone (13). In order to avoid reconstruction artefacts as much as possible in a computed tomography apparatus of this kind, in accordance with the invention it is proposed to arrange a modulation unit (33) between the radiation source (S) and the examination zone (13) in order to realize a temporally and spatially periodic modulation of the primary fan beam (41).

摘要： The invention relates to an arrangement for generating X-rays upon incidence of electrons (4), which arrangement includes a liquid metal zone (7) in which a liquid metal (9) is provided as an X-ray target in such a manner that it can flow past a zone of electron incidence (8).

摘要： In CSCT, by using a fan-shaped primary beam, combined with a 2D detector, single-slice transmission tomography and scatter tomography can be measured simultaneously. In such a System blurred scatter functions are measured unless a monochromatic source of radiation is used. According to the present invention, an energy resolving 1D or 2D detector System is proposed, which, in combination with a tomographic reconstruction, provides a good spectral resolution, even with a polychromatic primary beam. Furthermore, according to an aspect of the present invention, only one energy resolving detector-line is required to achieve the fall spectrum. Advantageous applications of the system and method according to the present invention are in medical imaging and material analysis, such as baggage inspection.

摘要： The invention relates to a computed tomography apparatus (CT apparatus) for imaging by means of radiation having traversed an object to be examined (that is, directly transmitted radiation), as well as by means of radiation scattered by the object to be examined, which apparatus includes a radiation source (S), a detector arrangement (16) and a device whereby the radiation (41a) having traversed the object to be examined can be blocked at least to an extent that the intensity incident on the detector arrangement (16) does not substantially exceed the intensity of radiation (41b) scattered by the object (13) to be examined and incident on the detector arrangement (16). The invention enables the detection of scattered radiation (CSCT mode) which is not affected by crosstalk from the transmitted radiation, even when the detector arrangement does not satisfy severe requirements as regards crosstalk properties and/or is configured as a single-row detector arrangement.

摘要： In conventional material discrimination, for example in baggage inspection, the attenuation coefficient of an item of baggage is used to identify the material in the baggage. However, the result can be ambiguous since there are often dangerous and non-dangerous materials having the same attenuation coefficient. According to the present invention, a method and apparatus are provided combining the information obtained from CT and Coherent Scatter Computed Tomography to better determine whether there are dangerous materials in the baggage or not. Hence, according to the present invention the attenuation coefficient and the diffraction pattern of the item of baggage are used to determine whether the baggage can be cleared or not.
