Pleural effusion (PE) is the accumulation of fluids around the lungs due to various diseases, such as cancer, liver and heart failure. Given the fact that fluid provides a high contrast in terms of dielectric constant at microwave frequencies, a radar-based microwave imaging system is proposed to utilise that change in properties for the early detection of PE. The system uses a wideband slot-loaded...
A new edge localisation technique for step edges in images with signal-dependent Rician noise in MRI is proposed. Dependent noise can not only affect the detection of true edges in an image but also their position. Inaccurate localisation of an edge can lead to insufficient segmentation and reduce the overall accuracy of any edge detection method. The proposed technique uses higher-order moments of...
