摘要
主要介绍磁纳米粒子在无创测温中的应用,并对磁纳米粒子的特性进行详细的说明。磁纳米粒子无创测温方法属于非侵入式测量,它的工作原理是磁纳米粒子注射进入体内后能适形分布于测试区域,磁纳米粒子可被看作无数个微小的温度传感器放置于测量区域,温度分布情况是通过测量其在外加磁场下的磁化率得到的。
Introduces magnetic nanoparticles noninvasive temperature measurement application, and describes the magnetic properties of nanoparti- cles in details. Magnetic nanoparticles noninvasive temperature measuring method which belongs to the non intrusive measurement, its working principle is that the magnetic nanoparticles injected into the body and distribute in the test area, which can be spread over the target area, it is seen countless tiny temperature sensor, the accurate temperature distribution will be caught by measuring the magnetic susceptibility in external magnetizing field.
