Among all existing medical imaging modalities such as MRI, CT, PET and SPECT, ultrasound (US) imaging is one of the most widely used in various applications such as ligament injuries, tendon injuries, bone injuries, cardiac imaging, blood flow estimation and obstetrics. Although Three-Dimensional Ultrasound (3D-US) has many benefits such as non-invasive, low cost, portable, real-time and non-ionizing,...
Robust tumor activity quantification recently finds application in challenging medical scenarios like early therapy response detection, radiotherapy treatment planning, etc. This paper targets a quantitative comparison of existing state of the art Positron Emission Tomography (PET) volume delineation methodologies. The different methods evaluated include adaptive threshold based, gradient based and...
Adaptive Anisotropic Filtering using local structure tensor analysis has been used for multi-dimensional ultrasound image enhancement. This paper presents a modified version of the existing framework for adaptive filtering mechanism with the view of application to ultrasound images. The goal of this work is to enhance and preserve important, typically anisotropic, image structures while suppressing...
Tensor based orientation adaptive filtering constitutes a flexible framework for image enhancement. In this paper, Local Structure Tensor (LST) based Adaptive Anisotropic Filtering (AAF) methodology is used for color image enhancement and denoising. This filtering framework enhances and preserves important, typically anisotropic, image structures while suppressing high-frequency noise. The goal of...
