摘要

与动脉粥样硬化斑块相关的因素可能预示着斑块的不稳定性,如溃疡、斑块内出血、脂质核心、薄或不规则的纤维帽以及炎症。灰度中值(GSM)是研究动脉粥样硬化斑块最常用的方法之一,因此全面规范图像后期处理非常重要。后期处理使用 Photoshop 23.1.1.202。通过调整灰度直方图曲线,将血管腔(血液)的最暗点设为零,远端血管边缘设为 190,从而对图像进行标准化处理。还进行了海报化和色彩映射。以易于理解和图文并茂的方式介绍当前技术水平的方法应有助于全球通分析的推广。本文逐步描述并说明了这一过程。

Grayscale median (GSM) post-processing, posterizing, and color mapping for carotid ultrasound.

Factors related to atherosclerotic plaques may indicate instability, such as ulcerations, intraplaque hemorrhages, lipid core, thin or irregular fibrous cap, and inflammation. The grayscale median (GSM) value is one of the most widespread methods of studying atherosclerotic plaques and it is therefore important to comprehensively standardize image post-processing. Post-processing was performed using Photoshop 23.1.1.202. Images were standardized by adjusting the grayscale histogram curves, setting the darkest point of the vascular lumen (blood) to zero and the distal adventitia to 190. Posterization and color mapping were performed. A methodology that presents the current state of the art in an accessible and illustrative way should contribute to the dissemination of GSM analysis. This article describes and illustrates the process step by step.
