Abstract This study proposes the usage of enhanced activation function to improve the performance of deep learning models used in MRI brain tumour segmentation. Activation function has a significant role in deep network stability, learning rate and accuracy of the resultant solution. The main advantage of this new activation function is the ability to provide more accurate results solving the problem of vanishing gradient in comparison to the common activation functions “ReLU”. Vanishing...
Abstract Quantitative elastography is a non-invasive imaging technique that studies the elastic properties of the tissue when force is applied, and gives quantitative information about it. In this research the present work was performed using static deformation on a breast mimic ultrasound phantom. Strain images are constructed from the measured radio frequency (RF) ultrasound signals. The mean strain is recovered from stiffer segmented lesion and from nearby normal tissue, and then compute ...
Sickle cell disease (SCD) is the most popular inherited blood disease, that red blood cells change its shape form circular shape to sickle shape and loses its main job which carries oxygen throughout the body. The watershed segmentation method has become highly developed for automated analysis of overlapping red blood cell microscopic images. The aim of this work is to suppress over segmentation problem which is a major drawback of the watershed algorithm. The experimental resultsshowed...
Abstract: Several new techniques are developed within the previous couple of years that convalesce results on special filters by take away the noise additional with success whereas protective the sides within the information .Image de-noising plays an important role in satellite communication and signal processing applications. In this research , I suggest an median filter ,NLmeansfilter ,Total Variation (TV) ,Hybrid Median Filtering (hmedian), Speckle Reducing Anisotropic Diffusion Filterin...
ABSTRACT The objective of this research is to identify the methods to improve current inspection and evaluation strategies for medical devices in health facilities. The research aims to emphasize the effect of proposed model variables (documents, visual inspection, risk management, preventive maintenance, performance indicators, corrective maintenance, inventory management, policies and procedures and vocational performance) on the dependent variable (the development of health care). The mos...
