计算机轴向断层扫描 (CT) 解释的各种限制部分是由于 8-13 毫米的标准组织平面厚度，部分是由于缺乏替代视图平面，例如冠状或矢状图像。本文描述了一种收集多个重叠的 8 mm 横向切片的方法，对这些数据进行反卷积处理，然后显示薄（1 mm）横向以及重建的冠状和矢状 CT 图像。描述了通过模型实验验证反卷积技术。将模型结果应用于人体死后 CT 扫描数据，说明当与大脑切片的实际标本照片相关时，该方法能够忠实地重建冠状和矢状组织密度。建议在当前第一代 CT 扫描仪上使用一种特殊的 CT 程序，即有限基底重叠扫描，而无需修改硬件。
The various limitations to computerized axial tomographic (CT) interpretation are due in part to the 8-13 mm standard tissue plane thickness and in part to the absence of alternative planes of view, such as coronal or sagittal images. This paper describes a method for gathering multiple overlapped 8 mm transverse sections, subjecting these data to a deconvolution process, and then displaying thin (1 mm) transverse as well as reconstructed coronal and sagittal CT images. Verification of the deconvolution technique with phantom experiments is described. Application of the phantom results to human post mortem CT scan data illustrates this method's faithful reconstruction of coronal and sagittal tissue densities when correlated with actual specimen photographs of a sectioned brain. A special CT procedure, limited basal overlap scanning, is proposed for use on current first generation CT scanners without hardware modification.
