Peterson x-ray
Airman 1st Class Krysta Haines, 21st Medical Support Squadron diagnostic imaging technician, allows other technicians to line up the X-ray machine for a training sinus X-ray at the 21st Medical Group clinic Feb. 18. One afternoon a month, the 21st MDG has downtime for training. The diagnostic imaging section took the time to perfect difficult X-ray positions and go over amount of radiation needed.
