Most mammograms are obtained using screen-film technique and must be digitized for teaching purposes. Digitizing mammograms poses special problems because of high contrast and multiple views. We describe the equipment and process for digitizing and consolidating mammograms for teaching purposes. These techniques can be applied to any type of images where consolidation may be helpful.
Mammograms are digitized using a high optical density scanner. After the window and levels are adjusted, a four-view mammogram may be consolidated into a single image if desired.
The high contrast of film screen mammograms is managed by using a high optical density scanner. Consolidation of image sets, such as a four-view mammogram, allows images to be easily inserted into text, slide, or poster documents.
Digitizing mammograms for teaching purposes is facilitated by use of a high optical density scanner and consolidation of image sets into single images. The techniques described are also useful for other areas of radiology in which display of multiple images or modalities is desirable.
大多数乳腺钼靶照片是采用屏-片技术获取的，为教学目的必须进行数字化处理。由于乳腺钼靶照片对比度高且有多个视图，对其进行数字化处理存在特殊问题。我们描述了用于教学目的的乳腺钼靶照片数字化和整合的设备及过程。这些技术可应用于任何可能有助于整合的图像类型。
使用高光学密度扫描仪对乳腺钼靶照片进行数字化处理。在调整窗宽和窗位后，如果需要，四张视图的乳腺钼靶照片可整合为一张图像。
通过使用高光学密度扫描仪来处理乳腺钼靶照片的高对比度。图像集的整合，如四张视图的乳腺钼靶照片，使得图像能够轻松插入到文本、幻灯片或海报文档中。
使用高光学密度扫描仪并将图像集整合为单张图像有助于为教学目的对乳腺钼靶照片进行数字化处理。所描述的技术在放射学的其他领域也很有用，在这些领域中需要显示多个图像或多种模态。
