Abstract
A measuring device includes a processor configured to acquire first transmission information by scanning an object to be measured with a detector that irradiates a predetermined object of irradiation and detects transmission information of the object of irradiation, acquire second transmission information by scanning a reference sample generated from the object to be measured with the detector, calculate a value relating to a weight or a thickness of the object to be measured from the first transmission information by using a correlation between a reference value relating to a weight or a thickness of the reference sample and the second transmission information, and calibrate the value based on variations of the second transmission information over time.

A measuring device comprising:
- a processor configured to:
- acquire first transmission information by scanning an object to be measured with a detector that irradiates a predetermined object of irradiation and detects transmission information of the object of irradiation;
- acquire second transmission information by scanning a reference sample generated from the object to be measured with the detector;
- calculate a value relating to a weight or a thickness of the object to be measured from the first transmission information by using a correlation between a reference value relating to a weight or a thickness of the reference sample and the second transmission information;
- and
- calibrate the value based on variations of the second transmission information over time.
A measuring method that is performed by a computer, the method comprising:
- acquiring first transmission information by scanning an object to be measured with a detector that irradiates a predetermined object of irradiation and detects transmission information of the predetermined object of irradiation;
- acquiring second transmission information by scanning a reference sample generated from the object to be measured with the detector;
- calculating a value relating to a weight or a thickness of the object to be measured from the first transmission information by using a correlation between a reference value relating to a weight or a thickness of the reference sample and the second transmission information;
