Horizon Postdoctoral Fellowships

AI-powered ultrasound imaging

Reference number: 14007
Supervisor: Hassan Rivaz

Program description

Ultrasound is a safe, fast and cost-effective imaging modality. Despite being one of the most popular imaging modalities, its potential is far more. Specifically, pre-beamformed channel ultrasound radio-frequency data (hereafter referred to as channel data) is not suitable for visualization, and as such, is beamformed to the familiar gray-scale ultrasound images. This conversion, however, is lossy and destroys most of the information in the channel data. In addition, current processing techniques that utilize temporal ultrasound data are limited, despite the increasingly high frame-rate capability of ultrasound. To better exploit channel data, a line of my research focuses on casting three image reconstruction problems of (1) beamforming, (2) deconvolution and super-resolution and (3) quantitative ultrasound (QUS) as inverse problems. We then develop novel deep learning (DL) techniques that exploit physics and unsupervised learning to solve the inverse problems in a data-efficient manner. A framework for solving inverse problems can also pave the way for extracting even more information from the channel data, such as going beyond the physical diffraction limit of ultrasound.

Academic qualifications required

  • PhD in Electrical and Computer Engineering, Computer Science or Biomedical Engineering.
  • Excellent publication record.
  • Excellent mathematical and programming skills.
  • Familiarity with medical imaging is not necessary but an asset.
  • Female and other underresented applicants are especially encouraged to apply.

Eligibility requirements

  • Applicants must not currently hold a postdoctoral appointment at Concordia
  • Priority will be given to postdoctoral fellows who have obtained their PhD from another university although in exceptional cases Concordia graduates may be considered
  • Applicants must adhere to the postdoctoral fellow eligibility criteria outlined in Concordia University’s Postdoctoral Policy

Timeline

Horizon position is expected to be filled as soon as possible but no later than March 1, 2024.
