摘要： The internal examination of a human organ (3) is made by means of an ultrasonic probe (2) inserted into the organ (3), analogue echo signals from the probe being converted to digital signals (8) which are then stored in a digital computer (10) where they are manipulated to produce a variety of three-dimensional representations of the interior of the organ for display on a terminal (12) or as hard copy (13).

摘要： In a method of manufacturing an ultrasonic transducer array (3) a plurality of discrete transducer elements (11) are formed on an initially flat flexible substrate (6) together with electrically conductive tracks (13), through which the transducer elements (11) will be energised in use, the flexible substrate (6) with the discrete transducer elements (11) and conductive tracks (13) mounted thereon then being formed into a cylinder and mounted on the end of a catheter tube, the substrate being radially outwardly of the transducer elements so that it is in a position to act also as an acoustic matching layer between the material of the transducer elements and the human tissues or blood when in use.

摘要： An ultrasound system comprising a transducer array and means for energising each element, or batches of elements, of the array in turn to generate an ultra sound pulse, means for processing an echo pulse received by each transducer, and control means for controlling the order in which a transducer or transducers are energised and the order in which a transducer or transducers receive an echo pulse, characterised in that the echoes resulting from the transmission of an ultrasonic pulse from any one transducer element are received by at least one other transducer element. There is also the feature that data from the array is digitised and procesed in a pipeline, the latter having means to divert/extract data from the pipeline and reintroduce it into the pipeline to enable images to be displayed retrospectively. There is also the feature that the ring down problem is overcome by the steps of generating a reference scan and updating it on the basis of a long term running average and then subtracting that running average from the current A-scan to remove the ring down.

摘要翻译：一种包括换能器阵列的超声系统和用于依次激励阵列的每个元件或多个元件的装置以产生超声脉冲，用于处理由每个换能器接收的回波脉冲的装置，以及用于控制每个换能器的顺序的控制装置传感器或换能器被激励，以及换能器或换能器接收回波脉冲的顺序，其特征在于由任何一个换能器元件传输超声波脉冲所产生的回波由至少一个其它换能器元件接收。还有一个特点是来自阵列的数据被数字化并处理在流水线中，后者具有从流水线转移/提取数据并将其重新引入流水线的装置，以使得能够追溯地显示图像。还有一个特征是通过生成参考扫描和基于长期运行平均值更新它的步骤来克服衰落问题，然后从当前A扫描中减去运行平均值以去除环。
