WET WIPES PACKAGING

The first wet wipes (moist wipes) appeared in the market in the 1970s. Today, most of the wet wipes are packed in flow wrapped bags, which usually counts with a re-closable lid or label, for opening the pack, extraction of a single wipe and closing of the pack to avoid de-hydration.

and fully automatic—therefore, having a high potential for clinical routine application. Its application yielded results comparable with those achieved by manual registration. However, patients showing large perfusion defects in se-verely misregistered areas could represent a weakness of this approach as compared with manual registration.

The overall goal of the presented approach is to enable a fully automatic data analysis that supports both the conventional AHA model perfusion quantification and a voxel-based segmentation of suspicious regions in the heart muscle. To this end, an automatic pipeline for detecting and segmenting perfusion defects was developed and evaluated.

Automatic registration of myocardical perfusion images

Myocardial perfusion is an indicator of heart health that can be used to locate dam-aged areas of the heart. It can be measured by an imaging modality such as magnetic resonance imaging (MRI). When measuring myocardial perfusion in a living human we must align images over time to correct for motion caused by breathing. In this thesis we will ...

The proposed CMR perfusion mapping method is implemented in-line, is fully automatic and is readily integrated into the clinical workflow via the Gadgetron framework . Thus, this technique seems to be ready for clinical implementation, making quantitative perfusion available as a routine examination in patients with suspected or established ...

Evaluation of renal transplant perfusion by functional ...

Abstract. Radionuclide angiography (RNA) is used as a noninvasive method for the evaluation of renal transplant perfusion. The computer processing method generally used, based on regions of interest, is unsatisfactory because it does not permit the regional differentiation of perfusion defects.

facts from actual perfusion defects. It is evident that accurate and automatic detection of myocardium on MCE is a critical and valu- able step and few studies have addressed the problem [6–8]. Computer aided diagnosis (CAD) system has been developed to identify the infarcted myocardium [9]. Many approaches have been

Surrogates of microcirculation and tissue perfusion can be assessed via blood samples, e.g., venoarterial CO 2 gap and lactate or non-invasively through evaluating the properties of the skin. Skin circulation is the first vascular system from which blood is diverted away from vital organs during a circulatory compromise.
