A digital X-ray image read apparatus with a correction function. |
摘要 |
In a digital X-ray image read apparatus with a correction function, the apparatus includes: an excitation beam generation source (3.4) for irradiating the excitation beam onto a photostimulable phosphor plate (3.1) to generate a fluorescent light; a collection unit (3.8) for collecting the fluorescent light of the photostimulable phosphor plate after excitation; a photomultiplier (3.9) unit connected to the collection unit for converting the fluorescent light to an analog electrical signal after multiplication; an analog-to-digital converter (3.11) operatively connected to the photomultiplier unit for converting the analog electrical signal to a digital X-ray image signal; a correction unit (3.13) operatively connected to the analog-to-digital converter for correcting the digital X-ray image based on a predetermined formula obtained from an amount of the fluorescent light and an afterglow thereof; and image memory (3.14) operatively connected to the correction unit for storing the X-ray image after correction. |
