Examinations can be performed at the bedside. As the investigation has to be performed with the patient in a supine position, application of the technology requires an examination couch, if possible, adjustable for height. To use the technology the only necessary disposable item is a water-based conducting gel to facilitate the transmission of the sound waves. As the technology is non-invasive, neither needles, nor bandages or medicines are necessary. The use of paper towels may be helpful to remove conducting gel from the skin after the investigation. {34}
