Abstract
This study aimed to provide a calibration criterion based on the condition number (Cond, Q) of the basis material matrix (BMM) to optimize experimental performance of basis of material decomposition (BMD) results. Cond(Q) was first elaborated theoretically and then phantom studies, including the possible influence of a number of experimental parameters, such as X-ray spectrum, the number of energy bins and the width of the energy bins, were performed to validate the criterion. In the BMD phantom study, the quantitative relationship between the proposed criterion and BMD accuracy was explored. Results showed that the proposed criterion was negatively correlated to BMD accuracy, and each of the experimental parameters influenced the criterion and BMD accuracy in a similar pattern. In conclusion Cond(Q) can be used to optimize experimental configurations of BMD.
