While x-ray computed tomography is a mature technology that is used for a wide range of diagnoses, there continue to be new untapped strategies to collect more information and to enable more efficient data collections (e.g. increased image quality and/or lower x-ray exposures). This talk will review new approaches that involve spatial and/or spectral variation of the x-ray beam as well as novel acquisition geometries. These new acquisition methods present additional opportunities and challenges. For example, new strategies often require new strategies for reconstruction and processing. Similarly, increased flexibility in the kind of data that may be acquired enables customized data acquisition - e.g. maximizing image performance based on the patient or the particular imaging task.
