PhD position for acoustic / ultrasonic imaging (m/f/x)
in Garching
Your tasks and responsibilities:
Particle therapy with protons and heavier ion beams is rapidly emerging as a promising radiation therapy modality due to the superior ability to concentrate energy deposition in the tumor, while better sparing normal tissue and critical organs compared to widely established photons. Despite considerable recent technological advances, full clinical exploitation of the favorable ballistic properties of ion beams is still hampered by the yet unsolved problem of range uncertainties in tissue. In this context, ionoacoustics has been identied over the last years as a promising modality to localize the maximum energy deposition (so- called Bragg peak) [1]. However, the strength and shape of the ionoacoustic signal crucially depend on the spatial distribution and temporal structure of the heating process, i.e., dose deposition. In clinical scenarios, this leads to weak pressures (up to some mPa) in the tenth of kHz frequency range [2], making the detection of the ionoacoustic waves a technological challenge. To overcome this challenge, our team proposed the use of contrast agents [3], aiming to enhance the ionoacoustic emissions and improve the co-registration with other imaging modalities (e.g., ultrasound or X-ray imaging). This will be the topic that the successful candidate will have the opportunity to investigate with our team in the framework of the recently granted DFG project “Contrast enHanced-IonoAcoustics in Proton and heavy Ion beam therapy” CHIAPI, see also.
As a part of the team, you will be actively involved in the assessment of novel contrast agents and the development of dedicated imaging strategies, including:
Simulation workow for in-silico assessment of the expected contrast agent performances in vivo in realistic clinical scenarios
-
Reconstruction of the dose in patients from contrast-enhanced ionoacoustic signals
-
Co-registration of ionoacoustics with patient anatomy from ultrasound morphological imaging and
additional pre-treatment images (e.g., X-ray CT)
-
Experimental demonstration and validation of the combined ionoacoustic/ultrasound imaging in a realistic phantom at clinical proton beamlines.
Your qualications:
■ Master’s degree in physics or biomedical engineering
■ Fluent English knowledge (spoken and written)
■ A transdisciplinary research orientation with demonstrated research experience or interest ■ Ability to work independently and collaboratively in a team environment
■ Motivated and self-driven with a passion for scientic research and innovation.Assessment criteria and other qualications
The candidates will be evaluated based on their qualications, suitability for the research topics, and potential as researchers. The following merits are seen as strong advantages:
-
Solid background in programming (preferably Python and Fortran)
-

-
Familiarity with photoacoustics and/or ionoacoustics with experience in thermoacoustic simulations (e.g., k-Wave toolbox)
-
Practical experience with data acquisition and image reconstruction techniques
-
Experience in carrying out research in international and multidisciplinary teams.
