The Volunteer State Community College Diagnostic Medical Sonography program is offering free ultrasounds for expecting moms in their second or third trimester this spring. The program organizes the scans so that Vol State students can gain experience with real obstetric patients. The scans will be performed in the Sonography Center at the Vol State campus in Gallatin. It’s equipped with six beds, HD screens, and state-of-the-art ultrasound machines. All ultrasounds are supervised by a Vol State faculty member.
