Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is increasingly in use as an investigational biomarker of response in cancer clinical studies. Proper registration of images acquired at different time points is essential for deriving diagnostic information from quantitative pharmacokinetic analysis of these data. Motion artifacts in the(More)
This paper proposes a modified bacterial foraging algorithm with a probabilistic derivative approach to detect edges in chromosome images. Chromosomal Edge Detection is fundamental for automatic karyotyping for noise reduction and getting useful messages from the edges. Subjected to staining and other imaging constraints, chromosomal banding patterns lack(More)
standard deformations. Any of these factors individually would seriously undermine the results of this work; combined together with the subsidiary points, the results and hence the conclusions of the article are invalidated. That being said, the contribution of the motion-free simulated data and the presentation of a new (applied to DCE-MRI) registration(More)
Birth Asphyxia is considered to be one of the leading causes of neonatal mortality around the world. Asphyxiated neonates require skilled resuscitation to survive the neonatal period. The project aims to train health professionals in a basic newborn care using a prototype with an ultimate objective to have one person at every delivery trained in neonatal(More)
Objective: The objective of this work is to evaluate the performance of OS extract as a coating on biomaterial surfaces in preventing bacterial adhesion and biofilm growth, as an effective measure to combat Biomaterial associated infections. Methods: Here, we have incorporated the extract from a medicinal plant as a coating to biomaterial surfaces in order(More)
