Call for participants in AAPM Grand Challenge (CT Metal Artifact Reduction (CT-MAR))

2023-11-02 22:13:42 88
The American Association of Physicists in Medicine (AAPM) is sponsoring the CT Metal Artifact Reduction (CT-MAR) Challenge leading up to the 2024 AAPM Annual Meeting & Exhibition. We invite participants to develop a 2D metal artifact reduction (MAR) algorithm. Both deep learning (DL) and non-DL approaches are welcome. Solutions can operate in the image-domain, in the sinogram-domain, or in a combination of both. A large set of image pairs and sinogram pairs will be provided for training and testing as well as a smaller dataset for scoring. The final score will be computed as a weighted average of dozens of clinically focused image quality metrics. The challenge organizers will summarize the challenge results in a journal publication. The top 3 teams will share in an award pool of $4,000 USD: $2,000 for the 1st place, $1,500 for the 2nd place, and $500 for the 3rd place (sponsored by GE HealthCare and Jiangsu First-imaging Medical Equipment). Additionally, one member from each of the two top-performing teams will be awarded complimentary meeting registration to present on their teams' methodologies during the 2024 AAPM Annual Meeting & Exhibition in Los Angeles, CA, July 21-25, 2024 (in-person attendance is required).
