ABSTRACT:
In a helical scanning type X-ray CT imaging system, a plurality of X-ray CT images of a biological body are reconstructed in synchronism with cardiac beats of a heart thereof to obtain such X-ray CT images free from image distortions. The helical scanning type X-ray CT imaging system comprises: an X-ray projection image data acquiring unit for acquiring continuous X-ray projection image data about a biological body under medical examination, while scanning both an X-ray source and an X-ray detector around the biological body in a helical scanning movement mode; an electrocardiogram data acquiring unit for acquiring a plurality of cardiac beats of a heart of the biological body as electrocardiogram data; a converting unit for converting temporal information contained in the electrocardiogram data into positional information of the biological body in connection with the helical scanning movement; and a reconstructing unit for reconstructing a plurality of X-ray CT images by processing the continuous X-ray projection image data based upon the positional information of the biological body, thereby producing the plural X-ray CT images having a specific relationship with phases of the cardiac beats of the heart.
