Participation at EMBC 2017

Date: 1 August, 2017

The Medical Imaging Laboratory was present at the 39th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), through researchers Ana Cecilia Saavedra and Junior Arroyo. The conference took place between July 11-15 at the International Convention Center on Jeju Island, South Korea, which covered a number of cutting-edge research topics in biomedical engineering, clinical research, technology transfer and entrepreneurship, as well as engineering education in biomedical sciences. The event included high-level lectures, exhibitions, tutorials, mini-symposia, workshops, oral and poster sessions.

Both Ana Cecilia and Junior presented their work orally, which corresponded to the area of elastography. Ana Cecilia presented the article “Measurement of surface acoustic waves in high frequency ultrasound: preliminary results”. In this work, she proposed the use of Crawling Waves for the formation and propagation of surface acoustic waves in skin using high frequency ultrasound (US). Preliminarily, experiments were performed on phantoms in two media: solid-water and solid-US gel, the latter being applicable in ultrasound. Thus, an empirical compensation factor was proposed in order not to underestimate the elasticity. These preliminary results show the feasibility of measuring surface waves and the potential of the technique in high frequency ultrasound for future dermatological applications. On the other hand, Junior presented the article ” Shear wave estimation by using shear wave holography with normal vibration: preliminary results “. Here he presented the main problem of sonoelastographic techniques: the mechanical coupling during the acquisition stage. In this way, a new technique was proposed, which takes advantage of this problem and allows the formation of a static interference pattern, from which a map of elasticity is calculated. Experiments were carried out on homogeneous phantoms, and the preliminary results obtained indicated a maximum error of estimation of 6%, which suggests that the technique presents a potential for continue being developed.

The following year’s conference will be held in Honolulu, Hawaii, USA. Both the researchers and their advisers hope to be present again in such an important event.
