MR病人量与液氦蒸发率以及MR效益比的关系

The relationship among the patient HOU gang number,the evaporation of LHE and the benefit ratio of MR

众所周知,非零消耗型超导磁共振液氦的蒸发率在一般情况下与病人量是无关的。在本文中,将介绍当病人量超过某一临界值时,液氦蒸发量会随着病人量的增加而增加。通过研究这一现象,可以更好的提高磁共振的效益比,并为医院购买增加新磁共振提供数据上的支持。

As we know,in the general case,the LHE of evaporation rate with non-zero consumption of superconductive MR is unrelated to patient number.In this paper,we will introduce that when the patients exceeds a certain critical number,the evaporation of liquid helium will be with the patient number increases.Through the study of this phenomenon,the benefit ratio of MR can be increased better and which can provide a support on data for the hospital to increase a new MR.
