Super-resolution (SR) ultrasound imaging, particularly through localisation and tracking of microbubble contrast agents (also known as ultrasound localisation microscopy or ULM), is a new exciting area of research in biomedical ultrasound with potential impact in a wide range of biomedical applications. In recent years many different SR methodologies and algorithms have been proposed by different groups and their applications to biological systems, pre-clinical models and clinical patients are being explored.

We challenge the participants to produce the best SR images using a set of data consisting of a number of contrast enhanced ultrasound image sequences generated through computer simulation and in-vivo acquisition. Participants are asked to submit:

1. Their SR imaging results in a pre-defined format;
2. A paper summarizing details of the methodology. Paper submissions should follow the IEEE IUS 2022 proceedings guidelines.

All accepted participants are required to prepare a poster for presentation during the ULTRA-SR workshop at IEEE IUS 2022 in Venice. Posters will remain visible during this 3-hour challenge summary workshop, as well as during the entire symposium.

The top 4-8 finishers will receive a cash prize of up to $1,000 USD and will have the opportunity to deliver oral presentations about their algorithms during this workshop.
