Abstract
Systems and methods of estimating radiation dose include obtaining at least one radiation exposure value from a location marked on a patient model. A radiation exposure of the patient is estimated using a dose model which includes the patient model. At least one correction factor is calculated based upon the radiation exposure value and the estimation of radiation exposure using the dose model. The at least one correction factor is applied to the dose model and a refined estimation of radiation exposure is produced based upon the at least one correction factor and the dose model.
Claims20
A system for estimation of radiation dose of a medical imaging system, the system comprising:
- a dosimeter adapted to be associated with a patient;
- and
- a processing unit that obtains at least one dose model comprising a patient model, receives at least one radiation exposure value from the dosimeter, marks a location of the dosimeter on the patient model, estimates the radiation exposure of the patient during an imaging procedure according to the dose model, calculates at least one correction value based upon the estimated radiation exposure of the patient according to the dose model and the at least one radiation exposure value received from the dosimeter, applies the at least one correction factor to the dose model and produces a refined estimation of radiation exposure of the patient based upon the at least one correction factor and the dose model.
A method of estimating radiation dose, the method comprising:
- obtaining a patient model;
- marking a location of at least one radiation exposure value measurement on the patient model;
- obtaining at a processor at least one radiation exposure value from a radiation exposure event;
- estimating a radiation exposure of the patient during the radiation exposure event with a dose model comprising the patient model to produce at least one dose model value;
- calculating at least one correction factor based upon the at least one radiation exposure value and the at least one dose model value;
- applying the at least one correction factor to the dose model;
- and
- producing a refined estimation of radiation exposure of the patient based upon the at least one correction factor and the dose model.
