.Exchangable Multi-cassette Direct X-Ray Imager Using Thin film transitor type Optical sensor

摘要

PURPOSE: A multifunctional digital x-ray real-time plate image system attached with a detachable light emitting part using a thin film transistor type optical sensor is provided to simplify the maintenance by substituting a necessary part instead of a whole module around a sensor and employing a detachable backlight projector cassette for image detection from an existing film instead of using additional equipments such as a scanner. CONSTITUTION: A multifunctional digital x-ray real-time plate image system attached with a detachable light emitting part using a thin film transistor type optical sensor(100) includes a detachable cassette independent module in which an x-ray visible ray converting scintillator faceplate produces a visible image out of a flash of light when radiating an x-ray closely to a TFT type optical sensor(86) module embedding a biological fingerprint image obtaining module for an index of an object(82b) and a TFT type optical sensor module for x-ray detection instead of using a lens, a detachable cassette independent module for detecting an image by coupling the TFT type optical module to an image(82a) projected via a backlight(88) at a rear part of a film by attaching a printed transparent x-ray film, and a detachable cassette independent module for inputting an opaque image for detecting the opaque image from a general or polaroid printing paper by using a backlight light source(84) embedded in the rear part of the independent TFT type optical sensor.
