Abstract
An X-ray diagnosis apparatus comprises an X-ray tube for projecting X-rays onto a subject, a two-dimensional X-ray detector for detecting X-ray signals from the subject, an image processing means for generating image signals to perform image display of the X-ray signal from the two-dimensional X-ray detector, and an image displaying means for displaying the image signal, and further comprises a noise eliminating means for generating noise correction signals from the X-ray signal of two scanning lines adjacent to each other out of a plurality of scanning lines of the two-dimensional X-ray detector and eliminating noise in an X-ray signal of the scan lines by using the noise correction signal.
Claims23
An X-ray diagnostic apparatus comprising:
- an X-ray tube for irradiating an object to be examined with an X-ray;
- a two-dimensional X-ray detector for detecting an X-ray passing through the object;
- image processing means for producing an image signal to display an image of the X-ray signal from the two-dimensional X-ray detector;
- and image display means for displaying the image, the X-ray diagnostic apparatus further comprising noise eliminating means for producing a noise correction signal from X-ray signals on two adjoining scan lines among a plurality of scan lines of the two-dimensional X-ray detector, and for eliminating a noise mixed in the X-ray signal of the scan line by using the noise correction signal.
