The main research activities are aimed at the development of measurement techniques and methods for applications in biomedical and industrial fields as well as the performance testing of biomedical instrumentation (e.g. Ultrasound Systems for diagnostic applications) with particular attention to the metrological characterization of the methods and techniques developed.
Nowadays, a commonly accepted reference standard for Quality Control (QC) of diagnostic ultrasound instrumentation is still lacking, and this may be due to different factors, including the progressive evolution of the ultrasound (US) technologies, and the difficulties in determining meaningful QC parameters able to objectively assess US equipment performance and to detect those defects that could affect clinical outcomes. The research activities focus on the definition, implementation and validation of novel Imaging and Doppler test parameters and procedures to determine the in situ performances and metrological characteristics of the US diagnostic systems. The parameters validation is carried out through the comparison of the outcomes obtained for several US diagnostic systems produced by different companies, thanks to the collaboration with the main international producers of medical equipment. With this aim devices of the same technology level are evaluated under the same approach and criterions. The proposed test protocols are US phantoms based, in order to assure an in situ evaluation at operating conditions, and range from spatial to contrast resolution, from depth of penetration to accuracy in distance measurements, flow sensitivity and accuracy, registration error, etc. In this context, a combination of the above test parameters is studied to be included in a novel Quality Assessment (QA) protocol for US medical systems testing: a first approach involving the use of the Kiviat diagram has been investigated, assuming the diagram area, normalized with respect to one of the gold standards, as an index of the overall US system performance.
Moreover protocols for the QA of ultrasound phantoms are also developed (e.g. stability check) through different methods and techniques (e.g. Short Time Fourier Transform).
