A 4-year postdoc position is available at the Center for Fast Ultrasound Imaging (CFU), Department of Health Technology from September 15 2020 sponsored by the European Research Council (ERC). It is conducted in collaboration between CFU and the MEMS group at DTU Health Tech, the University of Copenhagen, and the Copenhagen University Hospital (Rigshospitalet) in the ERC Synergy Grant “3-D Super resolution Ultrasound Real time imaging of Erythrocytes” - SURE.

The SURE project develops and researches a new super resolution ultrasound imaging method capable of resolving 3-D capillary flow in the human body. The approach tracks the motion of the individual red blood cells (erythrocytes) in a three-dimensional volume for a full visualization of anatomy, flow, and perfusion. The approach can potentially yield a paradigm shift in the scientific study, diagnoses, and treatment of cancer, diabetes, and vascular diseases at the capillary level, as it enables the possibility of volumetrically visualizing capillary perfusion in real-time at frame rates above 20 Hz without injection of contrast agents.

Responsibilities and tasks
The principle responsibility of the postdoc is to develop imaging schemes for acquiring the SURE data using row-column matrix arrays and optimizing the detection of the targets along with motion estimation in 3D. This includes performing a range of phantom and animal experiments to develop and refine the SURE imaging algorithms. Animal experiments are conducted with medical doctors at the University of Copenhagen, and the clinical studies are conducted in collaboration with Rigshospitalet in Copenhagen.

The research is conducted in a truly multi-disciplinary environment consisting of the 4 academic partners specializing in advanced ultrasound imaging, silicon CMUT probes, animal experiments, and clinical investigations, and the main purpose is to translate the SURE method from a research idea to the clinic.

The main task is to develop suitable ultrasound imaging schemes based on the previous work at CFU on synthetic aperture imaging with row-column matrix arrays and to make target isolation and motion estimation in 3D for high resolution motion correction and blood velocity estimation. This is integrated in our SURE processing framework and tested on 3D printed soft-tissue phantoms. The scheme is then implemented on our research scanners for pre-clinical trials and validation at the University of Copenhagen using GPU processing. The implementation will finally be clinically evaluated in human trials conducted together with the Department of Radiology at Rigshospitalet to reveal its efficacy.

Qualifications
Candidates should have a PhD degree electrical engineering, computer science or a similar degree. The candidate must have the following qualifications:

  • You are motivated by both individual and team accomplishments
  • You thrive on collaboration and teamwork
  • You have worked in an ultrasound laboratory with advanced research scanners
  • Have worked with row-column arrays and developed imaging schemes for them
  • Have prior knowledge of super resolution imaging
  • Have a desire to advance the field and help PhD students learn
