- Abstract:
- The differences in technical principles and clinical applications between kV-cone beam computed tomography (CBCT)
image-guided radiotherapy system and fan beam CT for diagnosis were analyzed, including differences in data acquisition, image
processing, spatial resolution, imaging dose, image noise, density resolution and so on. The differences in the requirements for
electrical safety and performance indexes in the technical review of CBCT and fan beam CT were further analyzed. Then the
requirements for CBCT user manual and registration unit division were also discussed. This analysis aims to provide some
references for manufacturers to apply for the registration of CBCT image-guided radiotherapy system.
