进行了体模和体外研究，以评价数字环形断层合成在乳腺和上颈椎成像中的潜在应用。使用原型体积X射线系统对乳房摄影体模、新鲜乳房切除术标本和包含上颈椎的头部体模进行成像。结果表明，乳腺组织可视化的能力，以产生截面图像，模糊覆盖的结构，并产生三维信息的钙化簇。在上颈椎成像中，数字环形断层合成摄影有效地模糊了覆盖的颌骨和颅骨结构，因此C1和C2可以在标准的前后位视图中可视化。
Phantom and in vitro studies were performed to evaluate the potential application of digital circular tomosynthesis in imaging of the breast and upper cervical spine. A prototype volumetric x-ray system was used to image a mammographic phantom, a fresh mastectomy specimen, and a head phantom containing the upper cervical spine. Results show that breast tissue visualization is improved by the ability to produce sectional images that blur overlying structures and yield three-dimensional information about calcification clusters. In upper cervical spine imaging, digital circular tomosynthesis effectively blurs overlying jaw and skull structures so that C1 and C2 can be visualized in a standard anteroposterior view.
