Unlike most publications ultrasonography is not seen as an alternative concept to x-ray localization of intraocular foreign bodies but as supporting aid. It is primarily used for the rather simple measurement of the form of the injured eye and not so much for direct search of the foreign body. The latter is rather difficult to perform intraoperatively. The combined method is based on the Comberg localization using a mobile x-ray television unit. The x-ray imagery shows quickly, exactly and clearly the localization of the foreign body in the orbita. The eye itself cannot be seen on the monitor, but ultrasonic data allow to add its contours, corrected individually. This work is done by a computer. The measurement of coordinates and angles usually performed by the investigator is done by a computer, too. The linkage of both x-ray and ultrasonic equipment to a computer relieves the surgeon of the graphical tasks and ultrasonic search for the foreign body; it also gives information about the localization of the foreign body in the individual case during the entire operation.
与大多数出版物不同，超声检查并不被视为眼内异物X线定位的替代概念，而是一种辅助手段。它主要用于对受伤眼睛形态进行相对简单的测量，而不是主要用于直接寻找异物。后者在术中相当难以实施。联合方法基于使用移动X线电视装置的康伯格定位法。X线成像能快速、准确且清晰地显示异物在眼眶中的位置。在监视器上看不到眼睛本身，但超声数据可以添加其轮廓，并可单独校正。这项工作由计算机完成。通常由研究者进行的坐标和角度测量也由计算机完成。将X线和超声设备与计算机相连，减轻了外科医生绘制图形和超声寻找异物的任务；它还能在整个手术过程中提供有关个别病例中异物位置的信息。
