Magnetic Resonance Imaging (MRI) suffers from several artifacts, the most common of which are motion artifacts. These artifacts often yield images that are of non-diagnostic quality. To detect such artifacts, images are prospectively evaluated by experts for their diagnostic quality, which necessitates patient-revisits and rescans whenever non-diagnostic quality scans are encountered. This motivates the need to develop an automated framework capable of accessing medical image quality and detecting diagnostic and non-diagnostic images. In this paper, we explore several convolutional neural network-based frameworks for medical image quality assessment and investigate several challenges therein.
磁共振成像(MRI)存在多种伪影,其中最常见的是运动伪影。这些伪影常常产生质量无法用于诊断的图像。为了检测此类伪影,专家会对图像的诊断质量进行前瞻性评估,这就使得每当遇到质量无法用于诊断的扫描时,都需要患者再次就诊并重新扫描。这促使人们需要开发一个能够评估医学图像质量并检测诊断性和非诊断性图像的自动化框架。在本文中,我们探索了几种基于卷积神经网络的医学图像质量评估框架,并研究了其中的若干挑战。
