1. A system comprising:
- a first radiation source;
a first detector configured to;
detect first radiation from the first radiation source during irradiation of a medium, wherein the medium includes one or more embedded objects;
a second radiation source oriented substantially orthogonally to the first radiation source;
a second detector located substantially orthogonally to the first detector configured to;
detect second radiation from the second radiation source during irradiation of the medium; and
one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising;
receiving first data from the first detector, the first data associated with the detected first radiation, the receiving the first data including determining, based on the first data, a first angle associated with at least one of the one or more embedded objects;
receiving second data from the second detector, the second data associated with the detected second radiation, the receiving the second data including determining, based on the second data, a second angle associated with at least one of the one or more embedded objects; and
determining a location of at least one of the one or more embedded objects based on the detected first data and the detected second data, the location being relative to the medium, the determining the location including;
determining a distance between the first radiation source and the second radiation source;
determining a first coordinate based on a first ratio of (i) the distance between the first radiation source and the second radiation source and (ii) a first function of the first angle and the second angle; and
determining a second coordinate based on a second ratio of (i) the distance between the first radiation source and the second radiation source and a second function of the first angle and (ii) the first function of the first angle and the second angle.
