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.
Fernando Bonilla-Musoles
Educated by the Jesuits, Bonilla graduated in Medicine from the University of Valencia in 1967, and received his PhD from that University in 1970. He had further study in Germany and Switzerland with Otto Käser. At that time, the first experimental apparatus for ultrasound in Gyncecology were being developed. His family financed the acquisition of the first three devices in 1969, which were installed at the Hospital Clínico Universitario of Valencia, in the old maternity hospital "La Cigüeña" and his own private practice, and he introduced obstetric and gynecologic ultrasound in Latin America in 70s.
