目的放射科医生和其他图像阅读器花费较长时间检查医学图像。视觉系统可以快速适应或调整对观察者当前正在观看的图像的敏感度，之前的研究表明，这可以导致对乳房X光检查图像的感知发生显著变化。我们比较了来自不同成像模式的图像的这些适应效果，以探索医学图像感知中适应的一般和特定的后果。方法我们测量了由于适应数字乳房摄影(DM)或数字乳房断层合成(DBT)获取的图像而引起的知觉变化，这两种图像具有相似和不同的纹理属性。参与者(非放射科医生)适应同一患者从每种方式获得的图像，或适应美国放射学会-乳房成像报告和数据系统(BI-RADS)对致密或脂肪组织的分类。然后，参与者判断通过混合两个适应图像形成的复合图像的外观(即，在每种模式中，DM与DBT或密集与脂肪)。结果适应于任何一种模式在对密集和脂肪纹理的感知方面产生了类似的显著变化，降低了测试图像中适应成分的显著程度。在并列判断中，没有观察到特定于通道的适应效应。然而，当图像在适应和测试过程中被直接注视时，不同模式之间的纹理差异更加明显，观察到图像对噪声的敏感度变化显著不同。结论这些结果证实，观察者可以很容易地适应医学图像的视觉属性或空间纹理，这可能会影响他们对图像的感知，而且适应也可以选择性地针对不同模式获取的图像的不同视觉特征。
PurposeRadiologists and other image readers spend prolonged periods inspecting medical images. The visual system can rapidly adapt or adjust sensitivity to the images that an observer is currently viewing, and previous studies have demonstrated that this can lead to pronounced changes in the perception of mammogram images. We compared these adaptation effects for images from different imaging modalities to explore both general and modality-specific consequences of adaptation in medical image perception.ApproachWe measured perceptual changes induced by adaptation to images acquired by digital mammography (DM) or digital breast tomosynthesis (DBT), which have both similar and distinct textural properties. Participants (nonradiologists) adapted to images from the same patient acquired from each modality or for different patients with American College of Radiology—Breast Imaging Reporting and Data System (BI-RADS) classification of dense or fatty tissue. The participants then judged the appearance of composite images formed by blending the two adapting images (i.e., DM versus DBT or dense versus fatty in each modality).ResultsAdaptation to either modality produced similar significant shifts in the perception of dense and fatty textures, reducing the salience of the adapted component in the test images. In side-by-side judgments, a modality-specific adaptation effect was not observed. However, when the images were directly fixated during adaptation and testing, so that the textural differences between the modalities were more visible, significantly different changes in the sensitivity to the noise in the images were observed.ConclusionsThese results confirm that observers can readily adapt to the visual properties or spatial textures of medical images in ways that can bias their perception of the images, and that adaptation can also be selective for the distinctive visual features of images acquired by different modalities.
