把机体的磁性信息,试用于临床医学的诊断历史不长,在日本正式研究也不过4～5年。作者试用肺磁图(MPG)测定接触粉尘工人肺内蓄积的粉尘量。测定的原理是从体外用磁化器将肺磁化使肺内粉尘带上磁性,在中断磁化之后,通过测定剩下的残留磁场就能知道其肺内蓄积的粉尘量及其分布情况。测定方法是用磁化器给受检者的胸部以一定强度的磁场,使体内蓄积的粉 The body’s magnetic information, the clinical diagnosis of probiotics in the history of not long, formal research in Japan, but also 4 to 5 years. The authors attempted to explore the amount of dust accumulating in the lungs of workers exposed to dust by using pulsed magnetic resonance imaging (MPG). The principle of the measurement is to magnetize the lungs from a magnetizer in vitro so as to bring the lungs’ dust to a magnetic state. After the magnetization is interrupted, the amount of dust accumulated in the lungs and its distribution can be known by measuring the remaining residual magnetic field. Determination method is to use the magnetizer to the subject’s chest to a certain intensity of the magnetic field so that the body of accumulated powder
