Device for determining a deposited dose and associated method

A method for determining a dose deposited under the effect of irradiation with ionising ionizing radiation during a radiological examination of a patient, the method comprising:

• providing a dose-determination device, including:
• at least one measurement probe comprising at least one optical probe defining two exit ends, the at least one optical probe comprising at least one active section made from a scintillator and intended to emit scintillation 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 scintillation photons emitted by the at least one active section to the two 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 so as to receive and count the scintillation 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 at least two photodetectors;
• and
• wherein the deposited dose is directly correlated to the amount of photons emitted under the ionizing radiation received by the patient undergoing the radiological examination;
• receiving, by the at least two photodetectors, scintillation photons emitted by the at least one active section under the effect of ionizing radiation and counting the scintillation photons;
• and
• determining the deposited dose from the counted scintillation photons received by the at least two photodetectors.
