Abstract
Objective:To explore the comparison of the accuracy and time between the automatic positioning of optical surface monitoring system(OSMS)and the traditional surface mark positioning in patients with special positions.Methods:Twenty radiotherapy patients in special positions were randomly selected.They were divided into two groups(A and B),10 cases in each group.Automatic setup guided by OSMS was used in group A(the OSMS group);traditional surface markers were used in positioning in group B(the surface mark group).Cone-beam CT(CBCT)scan was performed after setup.Scanned pictures were matched with the plan reference images.Translational errors in left-right(LR),superior-inferior(SI),anterior-posterior(AP)directions and the rotation errors in Roll-LR,Roll-SI,Roll-AP directions were obtained.The setup errors were corrected before implementing the treatment.Posi-tioning time in two groups were recorded before ending the treatment.Results:The errors in group A were(0.15±0.07)cm,(0.14±0.04)cm and(0.15±0.05)cm in LR,SI and AP directions,0.38°±0.14°,0.57°±0.10° and 0.55°±0.11° in Roll-LR,Roll-SI and Roll-AP directions.The errors in group B were(0.17±0.04)cm,(0.31±0.07)cm and(0.33±0.09)cm in LR,SI and AP directions,0.42°±0.15°,0.86°±0.11° and 0.81°±0.11° in Roll-LR,Roll-SI and Roll-AP directions.The differences between the two setup methods were statistically significant in y,z,Ry and Rz directions(all P＜0.01).The differences between them were not statistically significant in x and Rx directions(all P＞0.05).The setup time in group A was(135±32)s,in group B was(230±40)s,the difference between the two was statistically signifi-cant(P＜0.01).Conclusion:OSMS-assisted automatic positioning can effectively improve the positioning accuracy,reduce the positioning time and improve work efficiency for radiotherapy patients in special positions.关键词
