Successful Final Symposium

On 2 November 2022 the openGTN project held its Final Symposium. The meeting took place at partner University Medical Center Utrecht (UMCU) and was hosted by the Fall Meeting of the Dutch Society of Pattern Recognition and Image Processing (in Dutch: NVPHBV). A total of 100 persons registered. After a short introduction about openGTN by project coordinator prof. Marcel Breeuwer, keynote speaker prof. Sebastian Kozerke gave his view on the importance, status and potential of image simulation and synthesis. Thereafter, the 3 involved PhD researcher Sina Amirrajab, Aymen Ayaz and Yasmina Al Khalil presented their research achievements. All in all, a very successful meeting, with many interesting discussion during the breaks.

Two awards at the MICCAI CMRxMotion Challenge

The 25th International Conference on Medical Image Computing and Computer Assisted Intervention (MICCAI) conference was held 18-22 September 2022 in Singapore. At the conference, the openGTN PhD researchers Yasmina Al Khalil and Sina Amirrajab received two awards from the MICCAI CMRxMotion Challenge. They participated in two tasks: “Robust CMR Segmentation” and “Image Quality Assessment”, ended up 3rd in both! Ample synthesized image data was used to train the deep-learning neural network solutions that they implemented.

Final openGTN public symposium

at the University Medical Center Utrecht, The Netherlands
2 November 2022

The final public symposium of the Open Ground Truth Training Network (openGTN) project will take place on Wednesday 2 November, hosted by the Fall Meeting of the Dutch Society for Pattern Recognition and Image Processing (NVPHBV). The morning will be fully dedicated to openGTN: exciting new methods of MRI simulation and synthesis and their application to image segmentation will be presented by the involved PhD researchers. Keynote presentation will be given by prof. dr. Sebastian Kozerke from ETH Zurich. In the afternoon, more broader applications of simulation and synthesis will be presented, also outside the medical imaging domain.

The openGTN PhD team united @ TU/e

After a secondment of more than 2 years at Philips Research Hamburg, Germany, PhD researcher Yasmina Al Khalil returned to the Eindhoven University of Technology (TU/e), The Netherlands, to finalize her PhD thesis. The above picture shows the 3 openGTN PhD’s united in their room at TU/e.

The openGTN PhD team live @ ISMRM 2022

Finally, after 2 years of repeated COVID lock-downs and attending online-only conferences, the 3 openGTN PhD researchers Aymen Ayaz, Yasmina Al Khalil and Sina Amirrajab could all attend and present their achievements at the ISMRM 2022 conference. The left picture shows the team at the ISMRM exhibit booth, together with prof. Marcel Breeuwer.

First version of public database

The first version of the openGTN public database with simulated and synthesized MRI data will be made available on 31 December 2020. The database will contain cardiac, brain and spine data without pathology. Data with pathology is planned for March 2021. More information about the database can be found here.
