Abstract
A method for estimating a dose rate, based on measurements taken by a gamma camera, the gamma camera defining an observation field. The estimated dose rate originates from irradiating sources located in the observation field, the irradiating sources emitting ionizing electromagnetic radiation, and the observation field is discretized into a mesh. The gamma camera comprises pixels, each pixel being configured to detect the ionizing electromagnetic radiation, during an acquisition time, and form an energy spectrum therefrom such that together the pixels allow a position of the irradiating sources in the observation field to be obtained in one energy band or in a plurality of energy bands. The method comprising estimating a dose rate generated, at the gamma camera, by points of the mesh.
