Senior researcher at the Institute, Dr. Rytis Jurkonis, presented the intermediate results of the international project ‘Thrombus+’ at the ‘Biostec2025’
Dr. Rytis Jurkonis, a senior researcher at the Biomedical Imaging Laboratory, participated in the 18th international conference ‘Biostec2025′, held in Porto, Portugal, from February 20-22. The researcher presented a speech at the ‘Bioimaging’ session of the conference. Dr. Jurkonis discussed a full paper entitled ‘Automating Compression Ultrasonography of Human Thigh Tissue and Vessels via Strain Estimation’, co-authored by R. Jurkonis, R. Eitminavičius, V. Marozas, and A. Sakalauskas.
This article presents the results of integrated imaging with a tissue compression actuator and automated control of tissue deformation through strain estimation. The data for feedback control of the actuator is calculated from raw ultrasound radio-frequency backscattered signals. The region-averaged strain curve (strain versus time) obtained during the tissue compression cycle serves as input for the actuator. The mounting on the human thigh is made from rigid, pre-shaped shells, which are adjusted to the circumference of the thigh with straps. The actuator facilitates a novel, on-body-mounted, automated, operator-free examination of the human femoral vein.
The research is supported by the EU Horizon project ‘Thrombus+‘.
The conference was organized by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC). More information can be found here: BIOIMAGING2025.
