Abstract: A method includes obtaining a photosensor substrate (236) having two opposing major surfaces. 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A method includes performing a contrast enhanced computed tomography (CT) scan of tissue of interest of a subject, with an imaging system (100) having a radiation source (112) and a detector array (118), in which a peak contrast enhancement of the tissue of interest, a full range of motion of the tissue of interest, and an entire volume of interest of the tissue of interest are concurrently imaged during a single rotation of the radiation source and the detector array of the imaging system over an entire or a predetermined sub-portion of a breathing cycle.
