Correlation between Ultrasound and Simulated Location in Breathing Degree of Excursion of Liver Cancer in Radiotherapy
Yang Jin-lan · Guangxi Medical Journal · 2009
Objective To investigate the correlation between ultrasound and simulation location in breathing degree of excursion of liver cancer in radiotherapy.Methods Tumors breathing degree of excursion of 37 patients with primary or metastatic liver cancer were determined by ultrasound and simulator,the correlation between results of two methods was analyzed.Results The results of breathing degree of excursion determined by ultrasound and simulator had high positive correlation(r0.8,P0.05).Conclusion Ultrasound has a better correlation with simulator in breathing degree of excursion in liver tumors.Ultrasound detection can be served as an important method in location of liver tumors in radiotherapy.
