Abstract:
Objective To improve the set up accuracy for patients by MED TEC thermoplastic sheet. Methods First, a reference positioning line was scored on the supporting board of MEC TEC. Then, lines on the patient body were marked according to the reference positioning line. After fastening MED TEC thermoplastic sheet, CT top view imagines of patients who were immobilized with MED TEC thermoplastics sheet on the CT scanner were then drawn. The results by PC graphics software were analysed. Results A total of 57 cases was studied. Deviation in 52 (91.2%) cases was less than 3?mm. The cause of the with deviation exceeding 5?mm were all found.Conclusion Using the right method is very important. Thus, results with satisfactory deviations could be obtained when the set up are repeated.
