计算机在成像中的应用为医学图像信息的显示提供了极大的灵活性。为了在医学意义上有用，显示器必须是人类观察者在感知上可接受的，人类观察者必须能够从图像中提取相关的诊断信息。诊断信息由成像任务定义，因此，任务相关图像质量的概念非常重要。可视化和估计任务可能需要不同的视觉提示来完成。可视化任务需要强大的边界线索，而强度估计任务需要纹理线索。这两项任务都可以通过适当的图像显示来辅助。颜色可以帮助评估任务，三维显示可以帮助可视化任务。无论是什么任务或图像，只要需要观察者读出信息，性能就是图像好坏的最终仲裁者。
The use of the computer in imaging has provided great versatility for the display of medical image information. In order to be useful in a medical sense, the display must be perceptually acceptable to the human observer, who must be able to extract the relevant diagnostic information from the image. Diagnostic information is defined by the imaging task, and the concept of task-dependent image quality is, therefore, very important. Visualization and estimation tasks may require different visual cues for their performance. Visualization tasks require strong boundary cues, whereas intensity estimation tasks require texture cues. Both tasks can be aided by appropriate image displays. Color can be helpful in estimation tasks, and three-dimensional display can aid visualization tasks. No matter what the task or the image, as long as an observer is needed to read out the information, performance is the final arbiter of the goodness of the image.
