八、超声医学图象处理 1.超声医学应用简述由于利用超声波可以无损伤地获得病人体内深部脏器的形态或机能信息,所以在临床医学的各个领域日益得到广泛应用。与X线成象技术不同,超声诊断在观察软组织时,不需要作诸如注射造影剂之类的预处理,而且成象迅速,设备价格亦较便宜。超声波检查提供的信息形式基本上是图象信息,其方法可分为回波法和多普勒法两大类。 Eight, ultrasonic medical image processing 1. Ultrasound medical applications Brief description As the use of ultrasound can be obtained without damage to the body of patients with deep organ morphology or function of information, so in all areas of clinical medicine is increasingly widely used. Unlike X-ray imaging, ultrasound does not require preprocessing such as injection of contrast media when looking at soft tissue, and imaging is rapid and device prices are cheaper. Ultrasonic examination provides the form of information is basically image information, the method can be divided into echo and Doppler two categories.
