DICOM Freehand ROI Drawing Annotations File

Cornerstone is an open source project with a goal to deliver a complete web-based medical imaging platform. We using the cornerstoneDemo [1, 2] as a tool to annotate DICOM Images from a DICOM Server [3]. When annotating an image we would like to have several variables saved in a file (e.g.: JSON file), from the simple Freehand ROI feature [4, 5]. The features and variables that we would like to save are the following: 1) ID of the DICOM Image; 2) Frame number of the DICOM Image (if so); 3) Date of annotation; 4) Annotation coordinates related to the DICOM Image; 5) Number of ROIs [OPTIONAL]; 6) Number of annotations per each ROI [OPTIONAL]; References: [1] [login to view URL] [2] [login to view URL] [3] [login to view URL] [4] [login to view URL] [5] [login to view URL]
