Deep Representations for Ultrasound Imaging

7 Septembre 2023


Catégorie : Post-doctorant


Postdoctoral/Research Engineer Position

Ultrasound is a medical imaging modality appreciated for being real-time, nonradiative, low-cost, and portable. However, typical B-mode ultrasound images are 2D and suffer from a limited field of view. One way to enlarge the field of view is by acquiring a sequence of 2D images while tracking the ultrasound probe and then fusing the acquisitions from multiple viewpoints. This process is known as 3D freehand ultrasound. Another approach is with a 3D probe at the cost of image quality loss.

The aim of this project is to explore the latest advances in 3D scene representation and generative models and adapt them to the principles of ultrasound acquisition. Thereby, we seek to improve the current 3D capabilities of ultrasound imaging. Example directions are [1,2]. The candidate will have access to already collected data and to an in-house acquisition system with different acquisition modes: B-mode, plane-wave, with 2D or 3D probes.
