An improved simultaneous tomography cassette according to P. Landau was tried out for four months using four tomographs in routine work. The mode of operation is based on accurate control of the relative speeds of the individual x-ray films resulting in simultaneous imaging of 6 equidistant tomographic levels. Clinical testing was effected in 80 cases: nephrotomography, of the lungs, the hilum, and the skeleton. In particular, the article describes imaging of the renal arteries by simultaneous tomography for the purpose of finding out the cause of hypertension, and if there is suspicion of a space-occupying growth in the kidney, basing on the urogram. The specific advantages of this technique are, on the one hand, improved diagnostic efficiency (the tomograms are taken during the same respiratory phase, more rapid diagnosis especially with accident patients), and, on the other hand, an important reduction in the x-ray exposure of the patient; furthermore, the life of the x-ray tube is prolonged, and there is a definite saving of time for both patient and personnel, the image quality being comparable with that of single-layer tomography.
根据P. 兰道改进的同步断层摄影暗盒在日常工作中使用四台断层扫描仪进行了四个月的试用。其操作模式基于对各X射线胶片相对速度的精确控制，可同时对6个等距断层层面进行成像。对80例患者进行了临床测试：包括肾脏、肺部、肺门和骨骼的断层摄影。特别是，本文描述了通过同步断层摄影对肾动脉进行成像，以查明高血压的病因，以及在基于尿路造影怀疑肾脏有占位性病变时的情况。该技术的具体优点一方面是提高了诊断效率（断层照片在同一呼吸阶段拍摄，对事故患者尤其能更快速诊断），另一方面是显著减少了患者的X射线照射量；此外，X射线管的使用寿命延长，对患者和工作人员都有明确的时间节省，图像质量与单层断层摄影相当。
