  • Data processing and image reconstruction methods for pixel ...

    2007-6-11 · Pixel detectors equipped with an appropriate sensor chip (Si for small or light objects, e.g. soft tissue, GaAs or CdTe for larger or heavier objects) are well suited for CT. The measured projections can be linearized using technique described in Section 3.1.2. It has to be emphasized that this linearization method is fully precise just for ideal material composition of the object (soft …

  • Data processing and image reconstruction methods for pixel ...

    Iterative reconstruction (IR) methods have recently re-emerged in transmission x-ray computed tomography (CT). They were successfully used in the early years of CT, but given up when the amount of measured data increased because of the higher computational demands of IR compared to analytical methods.
