One of the two opposing major surfaces includes at least one photosensor row (230) of at least one photosensor element (232, 234), and the obtained photosensor substrate has a thickness equal to or greater than one hundred microns. The method further includes optically coupling a scintillator array (310) to the photosensor substrate. The scintillator array includes at least one complementary scintillator row (224) of at least one complementary scintillator element (226, 228), and the at least one complementary scintillator row is optically coupled to the at least one photosensor row (230) and the at least one complementary scintillator element is optically coupled to the at least one photosensor element. The method further includes thinning the photosensor substrate optically coupled to the scintillator producing a thinned photosensor substrate that is optically coupled to the scintillator and that has a thickness on the order of less than one hundred microns.

摘要： An imaging detector (214) includes a scintillator array (216) including a scintillator element (228) and a material (230) and a photosensor array (218) including a detector element (222) having a light sensitive region (224) and a non-sensitive region (226). The light sensitive region is separated from the scintillator element by a gap, the light sensitive region is in one-to-one mechanical alignment with the scintillator element, and the non-sensitive region is in mechanical alignment with the material. The detector further includes structure (234) that includes one or more material free channels. The structure is located between the non-sensitive region and the material and not between the light sensitive region and the scintillator element. An optical adhesive (232) is located in the gap, filling the entire gap, and mechanically and optically coupling the light sensitive region and the scintillator element.

摘要： An imaging system (300) includes a radiation source (308) that emits radiation from a focal spot (312) in a direction of an examination region. The imaging system further includes a beam shaper (314), located between the focal spot and the examination region, that shapes an x-ray transmission profile of the radiation emitted from the source and incident on the beam shaper such that the radiation leaving the beam shaper has a pre-determined transmission profile.

摘要： The invention relates to a rotor comprising a radiation source having a focal spot for radiating beam towards a subject, detection means for generating signals responsive to energy attenuation of said beam and a circular body having a cavity for housing the radiation source, and a circle arc-shaped surface on which the detection means are mounted. The circle arc-shaped surface is placed opposite to the cavity with respect to the subject, said cavity comprising an inside surface mounted with a shield for shielding the radiation not towards the subject. In this way, the conventional housing for radiation source and shielding are removed, resulting in reduction of focal spot motion caused by motion of the conventional housing. Furthermore, this invention proposes to mount the detection means directly on the circular body without an intermediate structural housing that reduces the detector modules motion relative to the focal spot.
摘要翻译：本发明涉及一种包括辐射源的转子，该辐射源具有用于朝向被摄体辐射光束的焦点，用于产生响应于所述光束的能量衰减的信号的检测装置和具有用于容纳辐射源的空腔的圆形体，以及圆弧形状的表面上安装有检测装置。圆弧形表面相对于被检体与空腔相对放置，所述空腔包括安装有用于屏蔽辐射而不是朝向被检者的屏蔽的内表面。以这种方式，用于辐射源和屏蔽的常规外壳被去除，导致由常规壳体的运动引起的焦点运动减少。此外，本发明提出将检测装置直接安装在圆形主体上，而没有中间结构壳体，其减小了检测器模块相对于焦斑的运动。
