Overview of participating centres and the data submitted to this study. Intra-application means that the applicators stayed in place between two image acquisitions, while inter-application means that applicators were removed and reinserted between image acquisitions. References for detailed descriptions of the individual study setups and/or individual centre’s standard practice are given in the last column.
