X-RAY DEVICE FOR MEDICAL EXAMINATION AND METHOD OF IMPROVING THE IMAGE QUALITY THEREOF |
摘要 |
The invention concerns an X-ray device 10 for medical examination comprising an X-ray source 3 emitting a beam 4 of X-rays towards an object 2 to be examined. An X-ray detector 5 is provided for receiving the X-rays passed through the object and connected to image processing means 6 for forming an image of said object. X-ray collimator means 9 are arranged between the X-ray source and the object to eliminate the effects of scattered radiation. The X-ray collimator means comprise a translatable element 9 that has at least one aperture 11 for narrowing the beam. The invention concerns also concerns a method of improving the image quality of such an X-ray device by means of the following steps: a) narrowing the beam 4 by means of at least one area 11 formed by the X-ray collimator means 9; b) moving the area through the beam for exposing the object to the narrowed beam and c) forming the object image based on the highest intensity value received by the detector 5 for each pixel.
