syngo.via Segmentation (VA30) 1. Functions of Segmentation  Create the volumetric evaluation  Lesion comparison after treatment 2. Segmentation steps: a. Open the patient using “assign workflow” or “view as read-only with “ to the MR General engine or MR Onco workflow  Note: If there are several series in the patient’s study, you can just select the series which you want to do the segmentation on. Load the series to the analysis workflow. The 3D images are better than 2D images in the segmentation processing. b. Transfer the images to MPR mode > invoke segmentation function  Note: It is recommended to use 3D MPR mode layout to do the segmentation, because the precondition of the segmentation is the image must be in MPR mode. There are two methods to do segmentation: Brush and Bounding box.
