We describe a visualization tool for the reporting of organ tumors such as lung nodules. It provides a 3D visual summary of all the detected and segmented tumors and allows the user to navigate through the display. The detected and segmented nodules are displayed, using surface rendering to show their shapes and relative sizes. Anatomic features are used as references. In this implementation, the two lung surfaces are rendered semi-transparent as the visual reference. However, other references could be used, such as the thoracic cage, airways, or vessel trees. The display is of 3D nature, meaning that user can rotate the objects as a whole, view the display at different angles. The user can also zoom the display at will to see an enlarged view of a nodule. The 3D display is spatially synchronized with the main window that displays the volume data. A click on a nodule in the 3D display will update the main display to the corresponding slice where the nodule is located, and the nodule location will be outlined in the slice that is shown in the main widow. This is a general reporting tool that can be applied to all oncology applications using all modalities, whenever the segmentation and detection of tumors are essential. It can also be extended as a visualization tool for combinatorial reporting of all relevant pathologies.
