X-ray diagnosis apparatus

An X-ray diagnosis apparatus for obtaining an X-ray image, comprising:

• an X-ray radiator configured to radiate an X-ray to a specimen;
• a detector configured to detect an X-ray data resulting from the X-ray;
• a shifter mechanism coupled to the detector and configured to shift the detector along a detecting plane of the detector;
• an exposer mechanism coupled to the X-ray radiator and configured to cause the X-ray to be exposed throughout an effective detecting area of the detector;
• a controller configured to control the second mechanism in accordance with the shift of the detector;
• and
• an image processor coupled to the detector, the image processor having a memory configured to store a past image data and being configured to prepare a fluoroscopic image data based on the detected X-ray data and a reference image data, based on the past image data, of a part of the specimen similar to what is viewed in the fluoroscopic image data in accordance with the shift of the detector.

An X-ray diagnosis apparatus for obtaining an X-ray image, comprising:

• a detector configured to detect an X-ray data resulting from the X-ray;
• a set of gears coupled to the detector and configured to shift the detector along a detecting plane of the detector;
• an X-ray radiator supporter coupled to the X-ray radiator and configured to move the X-ray radiator so as to cause the X-ray to be exposed throughout an effective detecting area of the detector;
• a controller configured to control the X-ray radiator supporter in accordance with the shift of the detector;
• an image processor coupled to the detector, the image processor having a memory configured to store one or more past fluoroscopic image data and being configured to prepare a current fluoroscopic image data based on the detected X-ray data and a contrast-enhanced reference image data based on at least one of the past fluoroscopic image data, and further to perform a subtraction processing between, the current fluoroscopic image data and at least a part of the contrast-enhanced reference image data, the part being determined in accordance with the shift of the detector;
• and
• a display coupled to the image processor and configured to display a subtraction processed image.
