Medical imaging currently relies on several techniques, including X-rays, magnetic resonance, and echography. However, these techniques exhibit drawbacks, alternative approaches are required. Microwave has been proposed as a possible solution, especially for breast cancer imaging. most of systems work with central frequency few gigahertz, this leads to suboptimum resolution, which can jeopardize the image quality. Millimeter waves provide superior resolutions, at cost lower penetration depth...
The effectiveness of radar interferometric techniques in non-urban areas can often be compromised due to the lack stable natural targets. This drawback partially compensated through installation reference targets, characterized by a bright and response. passive corner reflectors (PCR) represents valid aid, but these objects are usually cumbersome, suffer from severe weather conditions; furthermore, PCR difficult costly, especially places with hard accessibility. Active (AR) represent less...
Risk mitigation strategies to reduce the impact of avalanches on infrastructures, such as evacuation mountain villages, and planned closure roads, railways ski resorts, are heavily dependent avalanche forecasting capability. Moreover, possibility determine snow water equivalent (SWE) a snowpack is crucial step for management used, example, in agriculture hydroelectric power plants. In both cases, dry snow, two key physical parameters total thickness wave speed medium. Microwave radars being...
Breast cancer is one of the leading causes death among women in world. In recent years, there has been an increase incidence rate, but rate decreased. This due to improvement diagnostic techniques, which are making possible have diagnoses ever more precocious. However, all techniques currently use show limitations (such as ionizing radiation) and therefore new imaging being studied. Microwave millimeter waves systems, based on different behavior healthy tumorous tissues interest band, seen a...
Microwave radars represent a viable solution to perform rapid and nondestructive snowpack analyses. Depending on the working frequency, they are required provide suitable compromise between penetration depth spatial resolution. For these reasons, antennas able cover relatively large fractional bandwidths at few gigahertz fundamental, while minimizing antenna mass volume do not jeopardize portability often systems. This letter presents development experimental results of novel realized by...
Determining snow water equivalent (SWE) in a fast and nondestructive way is key request for many hydrologists scientists. To this aim, microwave ground-based radars represent viable solution, but often the simultaneous measurement of both snowpack depth density (the ingredients SWE) very complex, inaccurate, or requires difficult procedures equipment. This letter presents novel radar technique self-standing calculation SWE that can be applied to bi-static radars. technique, based on...
Breast cancer is the most common neoplasm in female population, affecting a woman every eight during her life. The trend of incidence between 2003 and 2017 appears to increase slightly while mortality continues decrease significantly. Early diagnosis increases likelihood having cure able overcome disease, for this reason mass screening programs are emphasized by all medical institutions. purpose early non-clinical phase. Currently, reference diagnostic technique senologic X-ray mammography,...
Breast cancer is a leading disease worldwide, and the success of medical therapies heavily related to availability breast imaging techniques. While current methods, mainly ultrasound, x-ray mammography, magnetic resonance imaging, all exhibit some disadvantages, possible alternative investigated in recent years based on microwave mm-wave system. A key point for these systems their reliability terms safety, particular exposure limits. This paper presents feasibility study system, with aim...
Abstract. This paper is focused on SAR interferometry for deformation monitoring, based the use of passive and active reflectors. Such reflectors are needed in all cases where a sufficient response from ground not available. In particular, describes development low-cost reflector. was carried out an EU H2020 project called GIMS. The summarizes key characteristics developed reflector tested two main experiments: first one located campus CTTC second GIMS test site Slovenia. experiments...
At microwave and mm-wave frequencies, the interactions of human tissue with electromagnetic fields depend on dielectric properties itself. The knowledge these healthy malignant tissues, beyond to be crucial in several biomedical applications, is necessary fix safety thresholds policy-making exposure limits for body. In particular, breast tissues are particular interest from medical social point view due relatively large diffusion cancer. literature, experimental data available up 20 GHz,...
