在过去的30年里，乳房X光检查为有乳腺癌风险的妇女提供了服务。虽然随着数字探测器技术的进步，乳房X线摄影术经历了许多变化，但其他模式，如计算机断层扫描，也在同一时间段内经历了技术复杂化。大视场平板探测器系统的出现使得乳腺CT和其他几种利基CT应用的发展成为可能，这些应用依赖于锥形束几何结构。事实证明，乳房非常适合锥形束CT成像，因为缺少骨骼减少了伪影，并且乳房向前的自然锥形减少了以大锥角通过乳房的X射线路径长度，也减少了锥形束伪影。我们正在设计第三个原型系统，该系统将使乳腺CT用于图像引导介入手术。该系统将制作多个副本，以便在多机构临床试验中使用多个乳腺CT扫描仪，以更好地了解该技术可以为乳腺成像带来的作用。
Mammography has served the population of women who are at-risk for breast cancer well over the past 30 years. While mammography has undergone a number of changes as digital detector technology has advanced, other modalities such as computed tomography have experienced technological sophistication over this same time frame as well. The advent of large field of view flat panel detector systems enable the development of breast CT and several other niche CT applications, which rely on cone beam geometry. The breast, it turns out, is well suited to cone beam CT imaging because the lack of bones reduces artifacts, and the natural tapering of the breast anteriorly reduces the x-ray path lengths through the breast at large cone angle, reducing cone beam artifacts as well. We are in the process of designing a third prototype system which will enable the use of breast CT for image guided interventional procedures. This system will have several copies fabricated so that several breast CT scanners can be used in a multi-institutional clinical trial to better understand the role that this technology can bring to breast imaging.
