A scientific paper that utilizes this dataset for deep learning has been [published](https://doi.org/10.1088/1361-6560/abb0f9). Underlying description of the technique and its first use has been described in a [previous publication](https://www.ncbi.nlm.nih.gov/pubmed/28803447). The data contains an image volume for each patient, for each echo time. The center of mass from the three inserted prostate gold fiducial markers was manually defined. The ground truth label for this dataset consist of spherical objects with a radius of 1-12 mm, inserted in the center of mass defined locations. Method in the paper uses 9 mm radius. info:eu-repo/semantics/restrictedAccess AIDA Data Hub AIDA Data Hub 2020-04-30T00:00:00Z
