$a A subfield of acoustics dealing in the radio frequency range higher than acoustic SOUND waves (approximately above 20 kilohertz). Ultrasonic radiation is used therapeutically (DIATHERMY and ULTRASONIC THERAPY) to generate HEAT and to selectively destroy tissues. It is also used in diagnostics, for example, ULTRASONOGRAPHY; ECHOENCEPHALOGRAPHY; and ECHOCARDIOGRAPHY, to visually display echoes received from irradiated tissues. $8 eng 550 $3 sllk_un_auth*d000069453 $Y Ultrasonic Waves $5 B $a vlny ultrazvukové 550 $3 sllk_un_auth*d000069453 $Y Ultrasonic Waves $5 F $a vlny ultrazvukové 686 $a H01.671.031.849 750 $a Ultrasonics $8 eng 801 -0
