Figure 1.  Presentation of the clinical (a) and the synchrotron radiation (b) computed tomography set-up
Figure 2 presents a flowchart of this iterative image reconstruction algorithm.
Figure 3.  Images acquired on the Catphan 504 phantom. MTF module on the top (a and b) and low contrast  module on the bottom (c and d) (a and c) are acquired at the hospital with the inner ear protocol (CTDI  183mGy)
Table 2 summarizes the quantitative results obtained on the Catphan phantom for the central background ROI  (worth scenario for SNR or CNR considering the artifacts seen on Fig. 3)
