Abstract
A digital X-ray image read apparatus having a correction function. The apparatus includes an excitation beam generation source for irradiating the excitation beam onto a photostimulable phosphor plate to generate a fluorescent light. A collection unit collects the fluorescent light of the photostimulable phosphor plate after excitation and a photomultiplier unit, connected to the collection unit, converts the fluorescent light to an analog electrical signal after multiplication. An analog-to-digital converter, connected to the photomultiplier unit, converts the analog electrical signal to a digital X-ray image signal. A correction unit, connected to the analog-to-digital converter, corrects the digital X-ray image based on a predetermined formula obtained from an amount of the fluorescent light and an afterglow thereof. An image memory connected to the correction unit, stores the X-ray image after correction.
