Advanced Science, EarlyView.ABSTRACT Infected diabetic wounds are sustained by a vicious cycle of hyperglycemia‐driven bacterial infection, persistent oxidative stress, and excessive inflammation, which collectively disrupt the ordered progression of tissue repair. Here, we engineered a stage‐adaptive Janus microneedle patch (MN‐FeSAC‐PPE) to enable a staged therapeutic process ...

Spectral optimization for micro‐CT
Medical Physics, 2012Purpose:To optimize micro‐CT protocols with respect to x‐ray spectra and thereby reduce radiation dose at unimpaired image quality.Methods:Simulations were performed to assess image contrast, noise, and radiation dose for different imaging tasks. The figure of merit used to determine the optimal spectrum was the dose‐weighted contrast‐to‐noise ratio ...

Spectral Distortion Compensation for Spectral CT
2020One of the challenges in photon counting detector (PCD)-based computed tomography (CT) is the spectral distortion in the PCD caused by physical effects such as charge sharing and K-escape fluorescence. This chapter summarizes for conventional approaches to compensate for the spectral distortion in PCD-CT and provides in great detail for a recently ...
