User Quote

"Data Explorer's data model is so powerful that it can handle almost any type of data. Because of the data model, this tool is not focused on a single application and has been useful in every viz situation I've encountered."

Data Explorer in Action

RAHD Oncology Products uses Data Explorer in commercial radiation treatment planning products. The Multidimensional Viewer (MDV) creates 3D structures from CT contours and 3D beams from beam parameters and blocking, and allows interactive review of structures, treatment beams, dose, CTs, and dose volume histograms. The 3D Beam Modifier (BM) provides interactive beam design in 3D, both manually and automatically, with interactive review of structures, treatment beams, CTs, and digital radiographs. It provides real time interaction and modification of select objects simultaneously in multiple windows. Each product utilizes DX very differently (both employ a separate Motif GUI):

The MDV utilizes the DX data flow, VPE, and user interface environments.
The BM is built entirely in C, using only the DX libraries (no data flow, VPE, or user interface).
