Don Konietzko, radiology director at Meeker County Memorial Hospital, shows Crackerjack Preschool students how radiologists "take pictures" of a person's insides during a field trip Tuesday morning. Konietzko showed students a radio, then used ultrasound equipment to show them the inside of the radio. This week is National Hospital Week, and students from throughout Meeker County have toured MCMH as part of the festivites.
