Specializes in Diagnostic Radiology

Physical Therapy: uses non-ionizing radiation. Xray and CT are ionizing radiation, which you should seek to reduce exposure to whenever possible. However, ultrasound, TENS and laser use sound, electricity and light energy which are generally regarded as safe in these therapeutic amounts.
