  With the availability of more powerful computing processors, iterative
reconstruction algorithms have recently been successfully implemented as an
approach to achieving significant dose reduction in X-ray CT. In this report,
we describe our proposal of an adaptive iterative reconstruction algorithm for
X-ray CT, that is shown to provide results comparable to those obtained by
proprietary algorithms, both in terms of reconstruction accuracy and execution
time. Implementation code in the C language is provided, along with example of
user interface.
