医用超声诊断仪器以其独特的优越性已广泛地应用于临床。超声诊断装置的不足之处是,由于受到某些物理特性的限制,不能用来检查骨骼组织和含气脏器。针对这种情况,日本东芝公司于84年10月研制成SSA-90A型四道超声诊断装置。
Medical ultrasound diagnostic instruments with its unique advantages have been widely used in clinical. The downside of an ultrasonic diagnostic device is that it can not be used to examine skeletal tissue and air-entrained devices due to certain physical characteristics. In response to this situation, Toshiba Japan in October 84 developed a SSA-90A four-channel ultrasound diagnostic device.
