The spine task in Stradview is based on the placement of multiple landmarks, three for each vertebra, from which offsets and rotations are deduced. It was designed for use with ultrasound data, and hence the landmarks are appropriate for what would be visible in this data, but it could also be used with CT or MRI. The task and visualisation are designed to make the creation and analysis of these landmarks easier, but they can also be edited in just the same way as normal landmarks, using the landmarks task.
Placement of landmarks is handled by the Spine task page, and information regarding these landmarks is displayed in the Spine visualisation page as well as in the 3D window. When selecting the spine task, the spine visualisation is automatically selected, as well as a reslice which shows all the acquired data through the spine, which will normally be in the sagittal plane. Landmarks can be placed either on this reslice or on the review window showing the original data.
