Patent ID: 7940976

Claim:
An X-ray image diagnosis apparatus comprising: a paired X-ray generating unit configured to radiate X-rays on an object and X-ray detecting unit configured to detect X-rays penetrated through the object and to generate X-ray projection data; an angle position setting unit configured to set at least two different radiography angle positions in a successive sequence for imaging the object by moving the paired X-ray generating unit and the X-ray detecting unit; a controller configured to control moving and performance of radiography operations of the paired X-ray generating unit and X-ray detecting unit based on angle position data supplied from the angle position setting unit and periodic vital data acquired from the object; a pixel data processing unit configured to generate a plurality of two dimensional pixel data using X-ray projection data supplied from the X-ray detecting unit positioned at the at least two different radiography angle positions during a time corresponding to at least more than one cycle of vital data; and a three dimensional image data generating unit configured to generate three dimensional image data using at least two of the two dimensional pixel data collected at a particular same phase of the vital data among the collected plurality of pixel data at each of the at least two different radiography angle positions generated by the pixel data processing unit; wherein the at least two different angle positions are sufficiently spaced apart to prevent occurring errors or distortions between two dimensional pixel data collected at the respective angle position of the at least two different angle positions.
