The present disclosure relates to a system and method of providing surgical assistance. The method includes obtaining a 3D space including an organ and a lesion located within the organ. Based on a shape of the organ, a grid is overlaid on a surface of the organ. The lesion is projected at a first location on an overlaid grid. A graphical tool disposed in a first orientation is positioned at the first location in the 3D space, and a plurality of parameter values of the lesion corresponding to the first orientation of the graphical tool are displayed in the 3D space. The graphical tool is manipulated to be disposed in a second orientation at a second location on the overlaid grid, and the plurality of parameter values of the lesion corresponding to the second orientation of the graphical tool are displayed in the 3D space.
