Since the advent of ultrasound scanning in the 1950s, the global movement to develop and expand its diagnostic features continue in its appeal with the medical community today. The ultrasound design using sound waves and echo reflection became widely accepted for being the safe (non-radiation), inexpensive, repeatable and non-invasive alternative in medical imaging. Early clinical upgrades included the development of the pulse Doppler paradigm (1966) to enable scanning layers of the heart via blood flow. This offered diagnostic advantages to its application in the mid-seventies for live-action scans of the human fetus. These qualities earned its place as the standard in pediatric use while continuing to earn the confidence of radiologists and imaging specialists for a wide range of diagnostic applications, from emergency critical care to supplemental cancer screening.
