我国引进CT 技术以来,在CT 诊断上有了飞快的发展。但在CT 机维修、故障检查方面尚无大的进展。目前引进CT 机已有几个国家十几个厂家生产的不同机型百台之多。由于CT 技术是先进的电子技术、计算机技术及光导技术与传统X 线技术的有机结合。面对这些新技术,CT 机的维修已经成为突出的矛盾。 Since the introduction of CT technology in our country, there has been a rapid development in CT diagnosis. However, there is still no big progress in the maintenance and troubleshooting of CT machines. At present, the introduction of CT machine several countries have produced more than a dozen different models of Taiwan as much. As CT technology is advanced electronic technology, computer technology and optical guidance technology and the traditional combination of X-ray technology. Faced with these new technologies, CT machine maintenance has become a prominent contradiction.
