Abstract :
This paper presents a filter bank (FB) analysis of parallel magnetic resonance imaging (PMRI). The underlying image reconstruction strategies of the most widely used PMRI reconstruction methods are unified within the framework and their fundamental perfect reconstruction (PR) constraints are analyzed. Based on this analysis, an improved reconstruction method, called H∞ optimal sense, is developed and its advantage is demonstrated by an example.
