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.
Ultrasound (band)
Despite the more commercially acceptable developments of their sound, the renamed band was initially no more successful. Following a year of struggling to keep going, Ultrasound released their first single "Same Band" on Fierce Panda in July 1997. It brought them some favourable press in "NME", who described it as "(sounding) like The Who's "Tommy" - in its entirety - squeezed into four-and-a-half minutes... utterly heroic and bizarrely, by some distance, their most understated moment." This led to the band performing in the "NME" sponsored Unsigned Showcase event.
