新型集成电路器件与中、高档B超诊断仪的研制开发

New type Integrated circuit devices and development of the advanced medical ultrasound scanner

本文扼要地介绍了新型器件在中、高档Ｂ超研制开发中的重要地位。首先介绍了ＰＬＤ、ＧＡ、ＳＣ等ＡＳＩＣ器件的简单原理、设计思想，指出了采用ＡＳＩＣ替代传统的ＳＳＩ／ＭＳＩ器件的优点以及在我国推广应用的困难。其后，文章又介绍了数字信号处理、图象处理及计算机专用芯片的基本情况。最后提出了对ＰＬＤ、ＳＣ、ＧＡ等ＡＳＩＣ器件和ＤＳＰ、图象处理以及计算机专用芯片在中、高档Ｂ超中进行应用研究的建议和设想。

This paper discusses briefly several new type integrated circuit devices an their important role in development of the advanced level medical ultrasound scanner. First, a brief introduction of the design principle and criteria of such ASIC devices as PLD, GA, SC, etc is made in the paper. Then, a discussion of the. advantages of using ASLC devices instead of traditional SSI/ MSI devices is devoted and an account of the difficulties in popularizing ASIC devices in China is given. In the paper, also a simple description of digital signal processors, image processors and new central processor units is given.At the end of the paper, a proposal on the possibility of introducing these latest devices into the advanced level medical ultrasound scanners is put forward.
