Séminaire Image: Medical Ultrasound Imaging: A Model-Based Beamforming Approach for Passive Acoustic Mapping par Tatiana Gelvez-Barrera
27 mars / 14:00 - 15:00
Nous aurons le plaisir d’écouter Tatiana Gelvez-Barrera, PostDoc à MINDS (Université de Toulouse III).
Elle donnera un séminaire IMAGE le vendredi 27 janvier 2026 à 14h en salle de séminaire F-200.
Titre : « Medical Ultrasound Imaging: A Model-Based Beamforming Approach for Passive Acoustic Mapping«
Résumé :
This seminar covers the basics of ultrasound imaging and its medical applications, with a focus on passive ultrasound imaging. This technique is used to create spatiotemporal maps from passively recorded ultrasound signals, which help monitor cavitation during therapeutic procedures. The talk will present a model-based beamforming framework for passive acoustic mapping. The approach combines a linear forward model with an inverse optimization process, incorporating prior knowledge of the sound sources’ spatiotemporal behavior to improve the quality of the reconstructed image.
