Abstract
A catheter tip-end rotation angle detection apparatus includes a catheter rotation angle detecting unit that detects a rotation angle of a catheter in an operator's hand, an image processing unit that extracts a catheter tip-end region from an x-ray fluoroscopic image of a first x-ray fluoroscopic capturing unit, a catheter tip-end rotation angle calculation unit that calculates an offset angle between an operator's hand-side rotation angle and a catheter tip-end rotation angle, from a fluoroscopic image captured at an action time of rotating the catheter by one turn, based on an angle at which a catheter tip-end region becomes a straight line in the image processing unit, and that calculates a catheter tip-end rotation angle based on the offset angle and the operator's hand-side rotation angle, during a catheter manipulation time, and an output unit that outputs the calculated catheter tip-end rotation angle.
