    • This document discusses, among other things, a computerized system comprising a perfusion analyzer circuit and a memory circuit to store a time sequence of volumetric image data. The image data is obtained in a time relation to arrival of a contrast agent at an anatomical region associated with the image. The perfusion analyzer circuit is configured to access the stored image data and receive a representation of an artery and a representation of tissue near the artery, shift the representation of the artery in time such that a time of arrival of the contrast at the artery precedes arrival of the contrast at the representation of tissue, automatically compute a perfusion parameter using the shifted representation of the artery, and provide the perfusion parameter as an output to a user or to an automated process.
    • 该文件尤其涉及包括灌注分析器电路和用于存储体积图像数据的时间序列的存储器电路的计算机化系统。 以与造影剂到达与图像相关联的解剖区域的时间关系获得图像数据。 灌注分析器电路被配置为访问存储的图像数据并且接收动脉的表示和动脉附近的组织的表示,以及时移动动脉的表示,使得在动脉处的对比度的到达时间先于到达 在组织表示时的对比度,使用动脉的移位表示自动计算灌注参数,并将灌注参数提供给用户或自动化过程的输出。
