Abstract
Among other things, radiation systems and techniques for generating volumetric data and projections images of an object(s) under examination are provided. The radiation system comprises at least two detector arrays and at least one radiation source. During an examination, the radiation source and at least one detector array are rotated about the object while a second detector array is substantially fixed in place. In one embodiment, the radiation source is configured to, at times, illuminate the first detector array and, at times, illuminate the second detector array. For example, the radiation source may illuminate the first detector array during nearly all of the rotation while the second detector array is merely illuminated at a single gantry rotation angle. Information generated by the second detector array may be utilized to yield volumetric data while information generated by the first detector array may be utilized to yield a projection image, for example.
