In digital mammography, the processes of image acquisition, display, and storage are separated, which allows optimization of each. Radiation transmitted through the breast is absorbed by an electronic detector, the response of which is faithful over a wide range of intensities. Once this information is recorded, it can be displayed by using computer image-processing techniques to allow arbitrary settings of image brightness and contrast, without the need for further exposure to the patient. In this article, the current state of the art in technology for digital mammography and data from clinical trials that support the use of the technology will be reviewed. In addition, several potentially useful applications that are being developed with digital mammography will be described.
在数字乳腺摄影中,图像采集、显示和存储过程是分开的,这使得每个过程都能得到优化。透过乳房的辐射被电子探测器吸收,该探测器在很宽的强度范围内都能如实响应。一旦记录下这些信息,就可以通过计算机图像处理技术进行显示,从而可以任意设置图像的亮度和对比度,而无需让患者再次接受辐射。在本文中,将对数字乳腺摄影技术的当前技术水平以及支持该技术应用的临床试验数据进行综述。此外,还将描述正在利用数字乳腺摄影开发的一些潜在有用的应用。
