This paper describes a method for imaging biosystems using radiation in the microwave frequency range (3.9 GHz). The advantages of interrogation with microwave radiation are discussed in terms of its physiological significance. An electromechanical scanning system for imaging isolated organs and the subsequent image processing techniques are described. Imagery is presented for a phantom target and an isolated canine kidney. The kidney images are interpreted in terms of the known anatomical and functional organization of the organ. It does appear to be possible to distinguish cortex corticis corresponding to a high proportion of proximal and distal convoluted tubules, deeper cortical layers corresponding to a high population density of glomeri, a medullary outer zone corresponding to the loops of Henle as well as the collecting system, and the region of calyces/renal pelvis.
本文描述了一种利用微波频率范围（3.9吉赫兹）的辐射对生物系统进行成像的方法。从其生理意义方面讨论了用微波辐射进行探测的优点。描述了一种用于对离体器官成像的机电扫描系统以及后续的图像处理技术。给出了一个模拟目标和一个离体犬肾的图像。根据该器官已知的解剖和功能组织对肾脏图像进行了解释。确实有可能区分对应于高比例近端和远端曲管的皮质，对应于肾小球高人口密度的更深皮质层，对应于髓袢以及集合系统的髓质外层区域，以及肾盏/肾盂区域。
