OSIPI Task Force 6.1: ASL Challenges

Task force aims

Develop and implement challenges involving ASL perfusion imaging analysis

Task force description

Task force 6.1 will develop challenges using that can act as broadly recognised benchmarks for perfusion software. This will include the development of metrics that quantify the performance of a perfusion analysis tool (eg. bias and precision on DROs, agreement with reference methods in-vivo, reproducibility on in-vivo data, processing time, etc). The challenges will use data collected by OSIPI and will be applied to the software tools listed in OSIPI in order to establish a set of benchmarks. The long-term aim is to establish OSIPI as an independent arbiter for software solutions in perfusion imaging.
