[Attempt at three-dimensional imaging in obstetrics]

Different attempts have been already made to present sonographic findings in 3 dimensions. In most of computer assisted systems the time for acquiring and data processing is too long to allow for an instantaneous interaction between the examiner and the machine; furthermore, valuable data; concerning the organ structure were lost. The aim of the system presented here is to acquire short time a sample volume for 3 dimensional display without employing an expensive periphery, containing all relevant sonic data and without substantial changes in handling the equipment. The technical details, advantages and shortcomings of the equipment are discussed. First results in obstetrics and gynaecology are presented.
