Portable ultrasound is a modality of medical ultrasonography that utilizes small and light devices, compared to the console style ultrasound machines that preceded them. In most cases these mobile ultrasound systems could be carried by hand and in some cases even operated for a time on battery power alone. The first portable ultrasound machines arrived in the early 1980s but battery powered systems that could be easily carried did not arrive until the late 1990s.

History[edit]

The ADR 2130, designed by Marty Wilcox was the first portable ultrasound unit commercially available in the United States, being released in 1975. This unit weighed about 25 lbs, had 3 linear probes to choose from and used an oscilloscope for a display instead of a TV monitor.[1] ADR was later purchased by ATL which later spun off its portable technology into a company that became Sonosite. ATL was later purchased by Philips while Sonosite came out with its first battery powered portable offering, the Sonosite 180 released in 1999.[2] Previous to this, Ecton produced a low-cost portable cardiac ultrasound system that could be carried by hand in March 1998, called the Sonnet[3] but the test prototypes were never put into full-scale production because of difficulty finding venture capital. Ecton was purchased by Acuson in 1999 and the Sonnet system was released as the Acuson Cypress Cypress portable ultrasound system in 2000.[4] The first battery powered portable was the Organon Teknika MiniVisor produced in 1979, but which saw only limited production. The device was created by a team led by Klaas Bom of the Erasmus MC and Organon Teknika.[5] The first dual-touch screen portable the Hyperion ultrasound system distributed through Graydon Pierce Imaging is designed specifically for the most hostile and demanding medical environments – Military Medical Applications (MEDCOM), Emergency Medical Services, Trauma Centers and Humanitarian Relief Operations. Recently GE has come out with the VScan and Vscan dual probe, which offer almost a micro-ultrasound. Importantly, its price point is such that they can be issued to individual physicians.

In November 2015,[6] 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[7]—Lumify is accessible to clinicians who might otherwise be unable to acquire an ultrasound system.

In 2016, Clarius Mobile Health launched a wireless portable ultrasound scanner that is compatible with iOS and Android devices.The Clarius ultrasound scanner has Point-and-Shoot Ultrasound™[8] capabilities, which optimizes common settings used by medical professionals at the point of patient care. To get started, clinicians download the free app from iTunes or Google Play stores, select their scanner, select a body part, and are ready to begin. In August 2017,[9] Clarius launched an update which incorporated enhanced capabilities for annotations, automated heart-rate monitoring during cardiac scanning, and easy bladder volume measurement. Additional premium options include Color/Power Doppler, spatial compounding, needle enhancement, and three-in-one clip-on imaging capability. Built with a rugged magnesium case, powered by a rechargeable battery and compatible with most smart devices, Clarius is designed to be used wherever ultrasound can improve patient care. Medical professionals can purchase or lease to own Clarius in many regions including North America, South America, Europe, Australia and parts of Asia. The free Clarius App also offers an interactive demonstration mode without the need to be connected to a scanner.

Uses[edit]

Portable ultrasound machines are typically used in situations where space is limited, mobility is important, or the scanning must be done in the field. OB/GYN doctors were the first to start using portable ultrasound systems as these could be brought bedside or were affordable enough to be purchased by a private practice. Currently portable ultrasound machines are used in Cardiac, Vascular, Radiology, Endocrinology, Pediatric and OB/GYN applications. In addition, EMS personnel from several countries including Germany, Italy, France, and the United States have used portable ultrasound evaluations in the field.[10]
