Abstract: A method for measuring and representing the level of local irradiation doses, in at least two dimensions, comprises: a step of positioning N probes Si sensitive to irradiating radiation, each corresponding to a local zone Zi according to a known topology; a step of acquiring, by each of the probes, the level of radiation ISi detected and periodically recording numerical values ISi(t); and a step of converting the numerical values ISi(t) into values DSi(t) corresponding to the radiation dose applied to each of the Z zones associated with a probe Si, according to a calibration table. The method further comprises, during the measurement sequence, steps of spatial interpolation calculation of at least one estimated irradiation level value ISiv(t) of at least one virtual zone Ziv that is not associated with a probe. A measurement device for implementing this method is also described.

Abstract: A device for determining an ionizing radiation dose deposited by a medical imaging apparatus during a radiological examination of a patient includes at least one measurement probe comprising at least one optical probe defining two exit ends, the optical probe comprising at least one active section made from a scintillator and intended to emit photons under the effect of incident ionizing radiation and at least two transport sections that are placed on either side of the active section and configured to transport the photons emitted by the active section to the exit ends; at least one detection system comprising at least two photodetectors, each photodetector being connected to one respective exit end of the optical probe to receive and count the photons received from the exit end; and at least one processing module configured to determine the deposited dose on the basis of the measurements carried out by the photodetectors.
