Monitoring patient movement with boron neutron capture therapy and motion capture technology.

In boron neutron capture therapy (BNCT), a patient must remain in a fixed position during the irradiation process. In this study, a system was devised that can guide a patient to the correct position and the patient can be monitored during the irradiation process. This is achieved by using motion capture technology that consists of many cameras. The discrepancy of the measured coordinates for each marker on a phantom by the system was less than 5 mm. For practical applications, further research and verification are required.
