Abstract：Objective To implement the automatic conversion between treatment coordinates and the coordinates of LAP DORADO 3 laser positioning system to determine the treatment isocenters of patients in radiotherapy and save relevant data. Methods The Visual Basic programming was used to design a program called TIC-CT3, which can achieve the automatic coordinate conversion. With the application of TIC-CT3 program, the input position data was calculated to obtain the final position data which can guide the shifts of laser lights and CT scanning table. Thus the treatment isocenters can be determined. Results With the application of TIC-CT3 program, the coordinate conversion and data calculation can be implemented quickly and manual calculation errors can be avoided. TIC-CT3 program which has various functions including data storage, report printing and error correction can facilitate the staff to operate the system and analyze relevant data. Conclusion The application of TIC-CT3 program with simple operating methods, good transportability and favourable application value can improve the work efficiency of relevant staff.
