Level of qualifications required : Graduate degree or equivalent

Fonction : Temporary scientific engineer

About the research centre or Inria department

The Inria Sophia Antipolis - Méditerranée center counts 34 research teams as well as 7 support departments. The center's staff (about 500 people including 320 Inria employees) is made up of scientists of different nationalities (250 foreigners of 50 nationalities), engineers, technicians and administrative staff. 1/3 of the staff are civil servants, the others are contractual agents. The majority of the center’s research teams are located in Sophia Antipolis and Nice in the Alpes-Maritimes. Four teams are based in Montpellier and two teams are hosted in Bologna in Italy and Athens. The Center is a founding member of Université Côte d'Azur and partner of the I-site MUSE supported by the University of Montpellier.

Assignment

This position is dedicated to the simulation of ultrasound imaging systems, from the transducer to the image through the body, to evaluate global performances in realistic conditions. The benefits of such a tool are manifold. First, it can improve the comprehension of image artifacts that appear in some clinical conditions. Second, it can be used to evaluate the performances of new beamforming algorithms. Third, it can be used to optimise probe design regarding specific applications (numerical phantoms). Last, it can help in defining probe specification based on resulting image quality instead of considering the acoustic performances of the transducer only.

Main activities

The main activity will be the numerical simulation of ultrasound image acquisition and reconstruction for cardiac applications.

Recent developments in artificial intelligence (AI) using deep neural networks could be leveraged to speed up the image generation process, improve the simulated resolution, and optimise the design parameters. AI has been shown to be very efficient in speeding up equation solving, estimating reduced order models and process spatio-temporal data.

This PhD thesis is the result of a collaboration between General Electric Healthcare (GEHC), the French National Research Institute for Digital Science and Technology (Inria), and Nice University Hospital (CHU Nice), started in 2017. It will leverage expertise of all these partners: GEHC in transducer design and cardiac imaging, Inria in cardiac modelling, and CHU Nice in clinical echocardiography.
