Arterial imaging and assessment systems and methods and related user interface based-workflows

In part, the disclosure relates to method of displaying a representation of an artery. The method may include storing an intravascular image dataset in a memory device of a diagnostic imaging system, the intravascular image dataset generated in response to intravascular imaging of a segment of an artery; automatically detecting lumen boundary of the segment on a per frame basis; automatically detecting EEL and displaying a stent sizing workflow. In part, the disclosure also relates to automatically detecting one or more regions of calcium relative to lumen boundary of the segment; calculating an angular or circumferential measurement of detected calcium for one or more frames; calculating a calcium thickness of detected calcium for one or more frames; and displaying the calcium thickness and the angular or circumferential measurement of detected calcium for a first frame of the one or more frames. 部分地，本公开涉及显示动脉的表示的方法。该方法可以包括：将血管内图像数据集存储在诊断成像系统的存储设备中，血管内图像数据集响应于动脉的节段的血管内成像而生成；在每一帧的基础上自动地检测节段的管腔边界；自动地检测EEL并显示支架
