A method for depth of interaction (DOI) estimation with temperature gradient was considered. Preliminary results covered measurements of bismuth germanate oxide (BGO) monolithic crystal light pulse dependence on temperature. The proof of concept for using temperature gradient as a way to encode DOI incident γ in monolithic BGO crystal was presented.
