Abstract
A radiographical image reader for photoelectrically reading a radiographical image of an object. The image reader comprises a radioactive ray irradiator; a radiographical image converting panel which is a radioactive ray absorbent for absorbing the radioactive ray passed through the object so that a radiographical image information is obtained; a scanner to scan the converting panel with exciting light so that the converting panel is subjected to stimulated emission; a reader to read the stimulated emission of the converting panel so that the radiographical image is obtained; a memory to store at least one of radioactive ray uneven generation information of the irradiator and sensitivity unevenness information of the converting panel; and a processor to compensate the radiographical image information according to at least one of the radioactive ray uneven generation information and the sensitivity unevenness information.
