Feasibility of Application of Mobile Shimadzu DR to Low-dose Lung Screening / 医疗卫生装备

ABSTRACT

Objective To explore the ideal parameters for the application of mobile shimadzu DR to low-dose lung screening.Methods 300 subjects were divided into two groups randomly,of which,one went through conventional screening with 120 kV voltage and 5mA current intensity,and the other through low-dose screening with 110 kV voltage and 1.2 mA intensity.Results All the images from two groups could satisfy the diagnosis requirements and had no aparent difference.Conclusion Low-dose screening,with similar result to the conventional one,can decrease radiation dose and prolong the service life of the machine,and thus can be used for examination of large-scale population.
