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.
Portable ultrasound
In November 2015, Philips launched a new era of portable ultrasound when it came out with the Lumify portable ultrasound machine, a first-of-its-kind portable ultrasound system that offers highly advanced transducers that connect via USB cable to off-the-shelf compatible Android devices. Ultrasound exams are performed on the free Lumify app, available at the Google Play Store, which offers features that most point-of-care ultrasound users are familiar with (such as entering patient data, depth, gain, color doppler, measurements, etc.). Because of the flexible pricing model—available as a subscription for as little as $199 per month, or available for outright purchase—Lumify is accessible to clinicians who might otherwise be unable to acquire an ultrasound system.
