In an x-ray scanning system having an x-ray source and an x-ray detector assembly, including a plurality of x-ray detector crystals grouped in substantially linear arrays and cooperative with the x-ray source, a substantially continuous radiation detection zone is established by positioning the detector arrays so that substantially all radiation from the source passing through the detector assembly passes through at least a portion of at least one detector crystal. The detector arrays are tilted at a preselected angle alpha with respect to a nominally perpendicular orientation relative to radial lines extending from the focal spot, so that the spaces between adjacent detector crystals in an array are not aligned with x-rays emanating from the x-ray source. The angle alpha is a function of the geometry of the detector crystals and the spaces between adjacent crystals in an array.
