Interaction techniques for a virtual workspace
The manipulation of medical image data, which increasingly come in 3D form (or 4D, with the time dimension), as Magnetic Resonance, CATscan, ultrasound, etc., has been our main concern given our research collaboration with the Johns Hopkins University. It is frequently necessary to revolve the display, to specify a cutting plane exposing (for example) a particular cross-section of brain data, to specify a point within a suspected tumour and ask the system to display the connected region of similar data values it appears to belong to, and so on. Here we briefly describe four medical applications that have been integrated into the Virtual Workbench.
