1. A computer-implemented method for visualizing a tumor in a volume data comprising: providing a plurality of tumors, detected and segmented from the volume data; storing locations of a plurality of voxels corresponding to each of the plurality of tumors; determining a mesh of surface voxels for each of the plurality of tumors from the stored locations; rendering the meshes for each of the plurality of tumors in a volume rendering window; selecting a tumor of interest from the plurality of tumors rendered in the volume rendering window; determining a correspondence of the selected tumor to a slice of the volume data, wherein the slice of the volume data is displayed in a main window.
