Comparison of time spent per patient.
Today’s therapy process using Gantry
15-20 min – immobilization and verification
1-3 min – irradiation
Full time is 20-30 min
On our installation
1-2 min – immobilization and verification
1-5 min – irradiation
Full time is 7-10 min
Creating many treatment rooms for irradiation is not necessary.
