IMAGE SCANNER FOR MEASURING ABSORBED DOSE OF RADIATION AND SCANNING METHOD

摘要

The present invention relates to an image scanner for measuring an absorbed dose of radiation. More particularly, the image scanner comprises: a light source unit for irradiating light; a gel detector which receives the light irradiated from the light source unit and is provided in the fluid of a water tank to absorb a predetermined amount of radiation; a control unit for generating a control signal for controlling a rotational direction or rotational angle of the gel detector; a rotating unit for rotating the gel detector on the basis of the control signal; a collimator for adjusting a quantity of the light penetrating the gel detector; and a photographing unit for generating an image showing the absorbed dose of radiation of the gel detector by continuously photographing the light passing through the collimator.
