Medical ultrasound
A contrast medium for medical ultrasonography is a formulation of encapsulated gaseous microbubbles to increase echogenicity of blood, discovered by Dr Raymond Gramiak in 1968 and named contrast-enhanced ultrasound. This contrast medical imaging modality is clinically used throughout the world, in particular for echocardiography in the United States and for ultrasound radiology in Europe and Asia.
Imagery analysis
This is also about the time when ultrasound would make its appearance. For the first time it was possible to view variations in tissue density which made it possible to detect possible tissue and organ anomalies. Another application was that of detecting material flaws in manufacturing.
