In the field of ultrasound imaging, resolution enhancement is an up-to-date challenging task. Many device-based approaches have been proposed to overcome the low resolution nature of ultrasound images but very few works deal with post-processing methods. This paper investigates a novel approach based on semi-blind deconvolution formulation and alternating(More)
Introduction Pharmacokinetic studies in rats are most effectively and humanely done using a chronically implanted catheter that allows repeated blood sampling. Once a catheter is successfully implanted, the amount of time that it reliably remains patent, with or without flushing, will set practical limits on its uses. The patency life can be affected by(More)
