摘要
在数字化超声成像系统中,由于原始数据量大,传输速率快,数据的有效传输一直是影响系统性能的主要瓶颈。我们介绍了一种基于光纤传输和PCI总线的高速医学超声数据传输系统的设计方案和功能特性。该系统应用于全数字化高帧率医学超声成像系统的数据传输,实现了将采集到的超声回波信号实时传送到计算机中进行成像处理。经测试,本系统实现的数据传输率可达80 MB/s。由于此数据传输系统具有较强的通用性,因此也可以应用于其他高速数据采集系统的数据传输。
Characterized by a large volume and high rate of data, the digital ultrasonic imaging system has a performance bottleneck in its data transmission. We introduced a high - rate medical ultrasonic data transmission system, based on optic fiber and PCI technology. The system made a real- time transmission of received ultrasonic signals to the computer where data will be concurrently processed for imaging. It is tested that the system＇s highest data wansmission rate can mount to 80MB/s. In addition, this data transmission system can also be referred to the design of other data acquisition systems.
