Medical ultrasound has transformed diagnosis and management in all areas of clinical medicine. However, current ultrasound imaging has limited spatial resolution, depends on bulky devices and is highly user dependend. HybridEcho is an interdisciplinary group of engineers, computer scientists and physicians working on methods and technologies to resolve these issues.

With our research group we cover the complete area of medical ultrasound, from transducer development over signal design to advanced algorithms.

EUROSON 2024

EUROSON 2024 – Annual Meeting of the European Ultrasound Society in Naples

During the second weekend of November, Julia, Tina, and Johanna, three members of the HybridEcho team, attended Euroson 2024 in Naples, Italy – a global meeting of ultrasound professionals focused on clinical applications and recent innovations in ultrasound technology. This annual event is a crucial platform for sharing insights, exploring groundbreaking research, and setting standards in the field.

Throughout the conference, we tested cutting-edge imaging technologies firsthand and assessed their potential impact on clinical practice. In addition to attending inspiring lectures, symposia, and workshops, we presented our latest research on the following topics: “Backscatter coefficient in focal liver lesions – Influence of attenuation correction” and “Backscatter Coefficient in Raw Ultrasound from Handheld Devices for Quantification of Liver Steatosis.”

Euroson 2024 offered a valuable opportunity to connect with other experts in the field, exchange ideas with national and international colleagues, and explore multidisciplinary perspectives on advancing ultrasound technology. The setting of Naples, with its unique atmosphere, provided an inspiring backdrop to an already enriching experience for the HybridEcho team.

We had the opportunity to present a variety of demos at the AI & Electronics for Medicine Conference 2024.

As an interdisciplinary research project, we’re driven by these questions:

– How can we improve the diagnostic output for physicians?
– How can we use 6G-based algorithms to get a better ultrasound picture?
– How can we build a probe to utilize advanced algorithms and signals?

That’s what we are demonstrating at the booth! We want to highlight the tremendous signal quality gains achieved by the hybrid technology approach together with optimized waveforms and processing compared to conventional piezo-based sensor systems.

Beyond that we’re excited to show you which technologies from our consortium partners are in the HybridEcho prototypes. Therefore the Fraunhofer IPMS shows their extremely sensitive MEMS with their cMUT Eval Kit and HETEROMERGE GmbH demonstrates their microscale 3D printing capabilities of Metamaterials.

We already had lots of interesting exchange and discussions and are looking forward to future cooperations. Many thanks belong to the Else Kröner Fresenius Center for Digital Health for the excellent organization of the event.

Julian shows Hybrid Acoustic Stacks at iMAPS Medical Workshop

Julian shows our embedded Hybrid Acoustic Stacks at iMAPS Medical Workshop
Last week Julian had the chance to attend and present our work on a novel ultrasound transducer concept at the iMAPS Medical Microelectronics Workshop in Arizona, USA.
 
To increase the resolution and therefore also diagnostic output of our ultrasound concept, we’ve used a broadband piezoelectric material to built a prototype. In combination with a transducer embedding in a flexible biocompatible substrate we’ve showed that this acoustic stack is able to emit comparable amplitudes of sound pressure in a laboratory setup in comparison with a traditional wire bonded solution. The flexibility of the shown solution could not only prove to be advantageous in our hybrid solution but also in other miniaturized medical applications as intravascular ultrasound (IVUS), ultrasound wearables and handhelds.
 
Our partners Eckardt Bihler, Gregor Schmidt and Marc Hauer from DYCONEX, Julius Weber from Contronix Engineering GmbH and Susan Walter from Fraunhofer IKTS have put a lot of effort into making the embedded acoustic stack possible. Many thanks to them.
 
In summary, the event was compact and delightful. Julian had the opportunity to connect with fellow researchers who specialize in medical microelectronics packaging for medical devices.

First results of the analysis of raw US data presented at the “Viszeralmedizin 2023”

We presented the first results of our analysis of ultrasound raw data at the ‘Viszeralmedizin 2023’.

In this study, we demonstrated the correlation between the attenuation in raw ultrasound signals of handheld devices and the CAP value of the FibroScan. The next steps will include the calculation of more sophisticated parameters as well as the implementation of AI. With this development, we hope to turn inexpensive handheld devices into valuable screening tools.

The Fraunhofer IKTS site in Dresden‐Klotzsche has been working since many years in research and development of methods and systems for nondestructive evaluation. It offers methods, sensors and devices for different kinds of nondestructive testing and covers the entire value chain, all the way to prototype production. For special applications, Fraunhofer IKTS designs and manufactures customized ultrasonic probes and methods based on model calculations that can be adapted to different geometries, materials and other acoustic parameters in the best possible way. With this knowledge, it supports the HybridEcho group in developing highly effective and broadband piezoelectric ultrasound emitters.
