1. A method for creating an image of a target, the method comprising: arranging a radioisotope source that emits positrons that collide with electrons, the collision emitting a first photon and a second photon; measuring by a gamma detector a first trajectory and a first time associated with the first photon; calculating by an imaging software module installed on a computer a second time and a second trajectory associated with the second photon; detecting by an imaging detector a scattered photon created from a collision between the second photon and a target, the imaging detector measuring a scattered trajectory and a scattered time associated with the scattered photon; and calculating by the imaging software module a position of the target based on the second time, the second trajectory, the scattered time and the scattered trajectory.
