| description | PROBLEM TO BE SOLVED: To provide an image processing apparatus and an X-ray diagnostic apparatus capable of displaying an image to facilitate the discrimination between a branching of one blood vessel and an intersection of the one blood vessel with another.SOLUTION: An image processing apparatus according of the present invention comprises: a parameter image generation unit which determines parameter values representing temporal information of the blood flow pixel by pixel, based on a pixelwise time density curve in a plurality of chronologically consecutive DSA images of a subject, and which generates a parameter image by determining the pixel value of each pixel according to the parameter values representing the temporal information of the blood flow; and an image binding unit which generates a road map image using at least a part of the parameter image, generates a composite image by combining the road map image with an X-ray fluoroscopic image of the subject captured in real time, and causes a display unit to display the composite image.SELECTED DRAWING: Figure 2
【課題】同一血管の分岐と他血管同士の交差との判別が容易な表示を行なうことができる画像処理装置およびＸ線診断装置を提供する。【解決手段】本発明の一実施形態に係る画像処理装置は、被検体の時系列的に連続した複数のＤＳＡ画像における画素ごとの時間濃度曲線にもとづいて画素ごとに血流の時間情報を示すパラメータ値を求め、前記血流の時間情報を示すパラメータ値に応じて各画素の画素値を決定することにより、パラメータ画像を生成するパラメータ画像生成部と、前記パラメータ画像の少なくとも一部を用いてロードマップ画像を生成し、リアルタイムに得られる前記被検体のＸ線透視画像と前記ロードマップ画像とを合成した合成画像を生成して表示部に表示させる画像合成部と、を備えたものである。【選択図】 図２ |
