Title:
CONTRAST CT SCANNER APPARATUS, OPERATION METHOD OF CONTRAST CT SCANNER APPARATUS AND METHOD FOR ACQUIRING CONTRAST CT SCAN IMAGE
Document Type and Number:
Japanese Patent JP2018139901
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a contrast CT scanner apparatus.SOLUTION: The contrast CT scanner apparatus according to the present invention includes: a control unit that receives basic information of a subject and a dynamic time phase index of a target blood vessel, a target organ, or a target disease; and a CT scan imaging unit that performs a first CT scan of the subject. The control unit receives the first CT scan image from the CT scan imaging unit, measures at least one morphologic predictor of the subject from the first CT scan image, and determines a time from start of administration of a contrast medium until a second and subsequent CT scans are performed, as correction scan timing on the basis of the basic information, dynamic time phase index and morphologic predictor of the subject. When the correction scan timing elapses from the start of the administration of the contrast medium, the CT scan imaging unit performs the second and subsequent CT scans, and the control unit receives the second and subsequent CT scan images from the CT scan imaging unit.SELECTED DRAWING: Figure 3B
