CT image scanning measurement result has high precision, but radiation exists, the measurement cost is high, and CT image scanning measurement is not suitable for patients who are subjected to radiotherapy due to the fact that the number of times of radiotherapy treatment courses is large. Meanwhile, the two measurement methods cannot monitor the change of the filling degree of the bladder of the radiotherapy patient in real time.
