1. A method for biomedical imaging, the method comprising: obtaining macroscopic data representing a volume of tissue; obtaining photographic data representing cross-sections of the volume of the tissue; obtaining microscopic data representing the cross-sections of the volume of the tissue; registering, with a processor, the microscopic data to the photographic data with a first transform of coordinate systems for the microscopic data and the photographic data; registering, with the processor, the macroscopic data to the photographic data with a second transform of coordinate systems for the macroscopic data and the photographic data; and generating, on a display, an image as a function of the microscopic data, macroscopic data, or both microscopic and macroscopic data and as a function of the registering of the microscopic data to the photograph data and as a function of the registering of the macroscopic data to the photographic data; wherein obtaining the macroscopic data comprises obtaining in vivo imaging data of the tissue, wherein obtaining the photographic data comprises photographing the cross-sections of the tissue in vitro prior to slicing, and wherein obtaining the microscopic data comprises obtaining in vitro imaging data of slices after slicing.
