Radiation dose and image quality in K-edge subtraction computed tomography of lung in vivo

S. Strengell, J. Keyriläinen, P. Suortti, S. Bayat, A. R. A. Sovijärvi and L. Porra

Radiation dose dependency of image quality was showed in in vivo rabbit lung images with and without a contrast agent using the synchrotron-radiation-based K-edge subtraction method. Consistency of the theoretical and measured radiation dose rate values was found.

Keywords: dosimetry; computed tomography; K-edge subtraction; image quality; lung imaging.
