    • In one embodiment, an X-ray diagnostic system is provided. The system is provided with an X-ray irradiation section, an X-ray detection section, an image data generation unit, a position detecting unit and a control section. The X-ray irradiation section radiates an X-ray to an object to be diagnosed. The X-ray detection section detects the X-ray radiated from the X-ray irradiation section and transmitted through the object so as to generate X-ray transmission data. The image data generation unit generates image data based on the X-ray transmission data. The position detecting unit detects position of a catheter inserted into the object. The control section switches X-ray irradiation conditions to be irradiated from the X-ray irradiation section, based on positional data detected by the position detecting unit and electrocardiogram data of the object.
    • 在一个实施例中,提供了X射线诊断系统。 该系统设置有X射线照射部,X射线检测部,图像数据生成部,位置检测部以及控制部。 X射线照射部将X射线照射到被诊断对象。 X射线检测部检测从X射线照射部照射的X射线并透过物体,生成X射线透射数据。 图像数据生成单元基于X射线透射数据生成图像数据。 位置检测单元检测插入到物体中的导管的位置。 控制部基于由位置检测部检测出的位置数据和对象的心电图数据来切换从X射线照射部照射的X射线照射条件。

    • A storage unit stores a plurality of vectors and a plurality of past electrocardiographic phases in association with each other. Each of the vectors is a vector from a past reference point to a past objective point. A Reference point specifying unit specifies a current reference point on a current image. An electrocardiograph detects a current electrocardiographic phase associated with the current image. A vector specifying unit specifies a specific vector associated with a past electrocardiographic phase corresponding to the detected current electrocardiographic phase among the plurality of vectors. Objective point calculation unit calculates a position of a current objective point on the current image based on the specified vector and the position of the current reference point. A display unit displays the position of the current objective point on the current image.
    • 存储单元相互关联地存储多个向量和多个过去的心电图相位。 每个向量是从过去参考点到过去目标点的向量。 参考点指定单元指定当前图像上的当前参考点。 心电图仪检测与当前图像相关的当前心电图相位。 矢量指定单元指定与多个矢量中检测到的当前心电相位相对应的与过去的心电图相位相关联的特定矢量。 目标点计算单元基于指定向量和当前参考点的位置来计算当前图像上的当前目标点的位置。 显示单元显示当前图像上当前目标点的位置。
