In order to evaluate the potential of superparamagnetically labelled neutrophils as inflammation-specific contrast agents for magnetic resonance imaging (MRI), various types of magnetite particles were associated with isolated human neutrophils in vitro and subsequent effects on characteristic cellular functions investigated. Exposure to uncoated magnetite(More)
In this paper we propose a method to improve the detection of shadowed flaws in ultrasonic non-destructive testing (NDT). The B-scans are expressed in the context of Sparse Signal Recovery (SSR), where the shadowing effect is incorporated during the reconstruction: Whenever a new defect is found, its shadow on all other dictionary atoms is determined and(More)
