Abstract: A method is provided including determining at least one range of phases of a cardiac cycle from which to select a selected phase based on at least one of patient demographic information, patient physiological information, or a general physiological model. The method also includes generating corresponding intermediate images for each of the phases of the at least one range of phases. Further, the method includes selecting the selected phase based on at least one image quality (IQ) metric of the intermediate images. Also, the method includes generating an image for diagnostic use using imaging information from the selected phase.
Abstract translation: 提供了一种方法，包括基于患者人口统计信息，患者生理信息或一般生理模型中的至少一个来确定从其选择所选择的相位的心脏周期的至少一个范围。 所述方法还包括为所述至少一个相位范围的每个相位生成相应的中间图像。 此外，该方法包括基于中间图像的至少一个图像质量（IQ）度量来选择所选择的相位。 此外，该方法包括使用来自所选择的相位的成像信息生成用于诊断使用的图像。

Abstract: A system and method for estimating vascular flow using CT imaging include a computer readable storage medium having stored thereon a computer program comprising instructions, which, when executed by a computer, cause the computer to acquire a first set of data comprising anatomical information of an imaging subject, the anatomical information comprises information of at least one vessel. The instructions further cause the computer to process the anatomical information to generate an image volume comprising the at least one vessel, generate hemodynamic information based on the image volume, and acquire a second set of data of the imaging subject. The computer is also caused to generate an image comprising the hemodynamic information in combination with a visualization based on the second set of data.
