Devices and methods for energy transfer mapping
The present disclosure relates generally to the field of energy transfer mapping, including fixtures with two-dimensional and three-dimensional sensor arrays. In particular, the present disclosure relates to devices and methods for mapping of energy transfer from and/or to an instrument inserted within and/or into body tissue, including the depths and patterns of penetration and/or amounts of energy transfer to and/or from an instrument delivered within biological tissue or materials that mimic biological tissue, including within fixtures with three-dimensional temperature sensor arrays configured to simulate anatomical geometries such as the gastrointestinal (GI) or respiratory tract.
