The low sensitivity is high that the magnetic resonance machine of low field consumes energy
It is reported ' Cub reporter Yan ShaoWei) On July 5, at the magnetic resonance scientific seminar of the low magnetic field in 2008, relevant reports claim, 0.4T permanent magnetism type magnetic resonance machine of low field that has just come into operation in BJ Union Hospital breaks the tradition, favored with the low-cost, low advantage of consuming energy etc.. According to the lush introduction in the land of dept. of radiology of Peking Union Medical College Hospital, the magnetic resonance instrument is on the basis of the intensity of magnetic field, divide for low field usually ' Smaller than 0.5T) , midfield ( From 0.5T to 1.5T) , high field ' 1.5T) With the field of superelevation ' Higher than 1.5T) . At present, 0.4T permanent magnetism type magnetic resonance machine of low field that this institute uses adopts the vertical magnetic field, it is 1.4 times of the signal sensitivity of horizontal magnetic field of resonance instrument of the traditional low magnetic field, can be used in whole body, including the image of positions such as brain central nervous system, four limbs bone joint, heart tumour, pelvis,etc. is diagnosed. The medical association of Beijing radiates and learns General Board Ma DaQing how to claim, what every large domestic hospital magnetic resonance is checked and generally adopted is the high field or superelevation field instrument at present, but such questions as its volume is large, the high, energy consumption of operating cost is strong have been perplexing staff members all the time. With the transformation from technology to low field intensity of some high field intensity, the magnetic resonance of low field of permanent magnetism is checked and taken shape with the magnetic resonance of high field complementarily in getting involved in treatment, joint movable formation of image, pediatrics patient and checking etc., only for high the intersection of field and magnetic the intersection of resonance and 1/10 of apparatus energy consumption its.
