skull base film

The skull base film is taken on the bottom of the skull to observe the cranial fossa in the skull base. When the X-ray machine is in working condition, the warning indicator on the radiation chamber door will be on. At this time, the patient will wait outside the protective door and do not wait for the film in the inspection room. If the patient does not need special care, the family should not enter the examination room to accompany them to reduce unnecessary radiation.
