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.
Research Group
- Prof. Dr. med. Jochen Hampe
- Prof. Dr.-Ing. Gerhard Fettweis
M. Sc. Edgar Dorausch
Edgar Dorausch first participated in the HybridEcho project as part of the “Clinicum Digitale” spring school. He later continued his work by writing his master’s thesis on Fourier-based multistatic image reconstruction. After receiving his Master’s degree in Computer Science in 2022, he joined the HybridEcho group as a PhD student. Under the supervision of Prof. Gerhard Fettweis, he is responsible for the development of new algorithms for image reconstruction and data compression.
Dipl.-Ing. Julian Kober
Julian graduated from TU Dresden in 2022 with a degree in mechatronics. He joined the HybridEcho research group of Dr. Moritz Herzog after attending the “Clinicum Digitale” spring school. In his diploma thesis Julian investigated the thermal behaviour of ultrasonic transducers during continuous broadband excitation. With the knowledge gained, he is continuing his work as a PhD student, focusing on the hybrid integration of broadband ultrasound transducers.
Dipl.-Ing. Daniel Swist
Daniel is a research associate at the TU Dresden Vodafone Chair for Mobile Communications Systems and pursues his PhD under the supervision of Prof. Dr. Gerhard Fettweis. He joined the HybridEcho research group in 2020 and investigates signal processing techniques and system architectures for novel hybrid ultrasound imaging in medicine, and common frameworks shared with joint communications & radar. Daniel graduated at TU Dresden in electrical engineering and previosuly worked on beamforming and mmWave technology.
Dipl.-Ing. Tönnis Trittler
Tönnis studied mechatronics at TU Dresden (2016 – 2022). Working as a student research assistant at Fraunhofer IWU he started his research career on the simulation of shape memory actuators. For his diploma thesis, he joined the research group HybridEcho of Dr. Moritz Herzog. There, he investigated the micromachining of the piezoelectric material PMN-PT with ultrashort laser pulses. After graduation he started his PhD on the manufacturing of broadband ultrasound transducers.
Dr. med. Antje Urbig
Antje is a Medical Doctor at the University Hospital Dresden. She joined the HybridEcho team in 2023 to conduct multi-centered clinical studies for the analysis of RF Data under the patronage of Dr. Herzog and Prof. Hampe. Antje graduated 2016 at the TU Dresden in Medicine and worked in Switzerland before returning to the University Hospital Dresden in 2021.
Omid Chaghaneh
Omid joined our group in 2023. He studied mechanical engineering and additionally did a master in computational modelling and simulation. He leads the simulations in the HybridEcho group, ranging from mechanical simulations microstructures to electrical crosstalk.
Charlotte Herzog
Charlotte is studying Medicine at the Ludwig-Maximilian-Universität München. She joined the team 2023 during her research for a doctoral thesis, collecting and analyzing ultrasound data from patients with gastrointestinal tumor using quantitative ultrasound.
Cornelius Kühnöl
Cornelius studies microelectronics at the Friedrich-Alexander-University (FAU) Erlangen Nuremberg. For his master’s thesis, he is participating in the HybridEcho project and evaluating different signal shapes for their application in Multiple Input Multiple Output (MIMO) ultrasound imaging. His official supervisor at TU Dresden is Daniel Swist.
Jakob Schäfer
Jakob studies medicine at the University of Halle since 2021. He joined the group after participating in the Clinicum Digitale for his medical thesis on the analysis of raw ultrasound data of the liver. After completing his first degree, he focused his research on quantitative ultrasound.
David Toppe
David studies human medicine at the medical faculty of the TU Dresden. He joined the HybridEcho group after visiting the Clinicum Digitale 2021 for his thesis. In his medical thesis he evaluates objective parameters of ultrasound image quality using phantoms and an image analysis tool.
Julius Weber
Julius Weber is studying mechatronics at TU Dresden. He joined the HybridEcho-Group as student assistant in 2022 and continued his support of the group with his diploma thesis in 2023. In his thesis he is developing the analog frontend in a cooperation with Contronix.
Cooperating Research Institutes
Fraunhofer IPMS
In collaboration with Fraunhofer IPMS, the HybridEcho Group investigates the potential of capacitive micromachined ultrasonic transducers (CMUTs) for ultrasonic applications. With many years of experience in ultrasound MEMS technology and its highly flexibel clean room processes Fraunhofer IPMS is supporting the special requirements of the HybridEcho development for super wideband signal use.
