Trial lecture

  • September 6, 2023 11:15 AM, Kristen Nygaards sal (5370), Ole Johan Dahls hus
  • Title:  "Super-Resolution for medical images using AI: state of the art in CT/MRI and limitations for extending to echocardiography"

 

Main research findings

Echocardiography, i.e. ultrasound imaging of the heart, is the most frequently used modality and to be able to save clinicians’ time when analyzing such exams, automatic algorithms are being developed mainly using Deep Learning techniques. However, privacy concerns, limited data availability and variability in echocardiography images pose significant challenges for developing such models. Therefore, this thesis described the developed and applied deep generative models that can efficiently and accurately generate synthetic 2D and 3D echocardiography images, with a high realism level. Results showed that the synthetic images are realistic and are a helpful and relevant resource which can be used to develop the Deep Learning algorithms for echocardiography image analysis, this way facilitating clinical workflows, as they represent a promising step towards more efficient and effective medical imaging and diagnosis.
