A preliminary study of the assessment of the cosmetic outcome of the breast aft...
Gonçalves, Maria; Porter, Emily; Conceicao, RaquelBreast cancer patients struggle with psychological trauma related to body image issues linked to the required treatment. Thus, minimally invasive treatment modalities, such as microwave ablation, have been gaining attention. Additionally, personalized pre-treatment simulations that allow assessing the cosmetic outcome of the ablation can help reduce associated trauma. The aim of this paper is to propose a frame...
Repository of materials mimicking dielectric properties of biological tissues
M. Godinho, Daniela; Bonello, Julian; Farrugia, Lourdes; Porter, Emily; C. Conceição, RaquelAnatomical phantoms with Tissue Mimicking Materials (TMMs) representing the properties of biological tissues, such as dielectric properties, are essential for validation of electromagnetic (EM) medical devices. In this paper, we present an open-access repository of TMMs that aims to collect and summarise ingredients and recipes of TMMs used for these applications. This repository allows to avoid duplicated effo...
Repository of MRI-derived models of the breast with single and multiple benign ...
Pelicano, Ana C.; Gonçalves, Maria C. T.; Castela, Tiago; Orvalho, M. Lurdes; Araújo, Nuno A. M.; Porter, Emily; Conceição, Raquel C.The diagnosis of breast cancer through MicroWave Imaging (MWI) technology has been extensively researched over the past few decades. However, continuous improvements to systems are needed to achieve clinical viability. To this end, the numerical models employed in simulation studies need to be diversified, anatomically accurate, and also representative of the cases in clinical settings. Hence, we have created t...
Development of 3D MRI-Based Anatomically Realistic Models of Breast Tissues and...
Pelicano, Ana Catarina; Gonçalves, Maria C. T.; Godinho, Daniela M.; Castela, Tiago; Orvalho, M. Lurdes; Araújo, Nuno A. M.; Porter, EmilyBreast cancer diagnosis using radar-based medical MicroWave Imaging (MWI) has been studied in recent years. Realistic numerical and physical models of the breast are needed for simulation and experimental testing of MWI prototypes. We aim to provide the scientific community with an online repository of multiple accurate realistic breast tissue models derived from Magnetic Resonance Imaging (MRI), including beni...
Development of a Transmission-Based Open-Ended Coaxial-Probe Suitable for Axill...
Savazzi, Matteo; Porter, Emily; OHalloran, Martin; Costa, Jorge R.; FERNANDES, CARLOS; M. Felício, João; Conceicao, Raquel C.We assess the feasibility of a transmission-based open-ended coaxial-probe for tissue dielectric properties estimation. The ultimate goal is to use it for axillary lymph node dielectric measurement, which is not trivial when applying the state-of-the-art reflection-based open-ended coaxial-probe. The proposed technique consists in placing the material under test between two opposite open-ended coaxial-probes an...
Development of an Anthropomorphic Phantom of the Axillary Region for Microwave ...
Savazzi, Matteo; Abedi, Soroush; Ištuk, Niko; Joachimowicz, Nadine; Roussel, Hélène; Porter, Emily; O’Halloran, Martin; Costa, Jorge R.We produced an anatomically and dielectrically realistic phantom of the axillary region to enable the experimental assessment of Axillary Lymph Node (ALN) imaging using microwave imaging technology. We segmented a thoracic Computed Tomography (CT) scan and created a computer-aided designed file containing the anatomical configuration of the axillary region. The phantom comprises five 3D-printed parts representi...
