Ultrasound e bolela leqhubu la mochini (frequency>20 kHz) le fetang sebaka sa kutlo sa tsebe ea motho, 'me mofuta o phahameng oa maqhubu (frequency>100 kHz) o bitsoa high-frequency ultrasound. Maqhubu a lisebelisoa tsa morao-rao tsa ultrasonic hangata a tloha ho 20 kHz ho isa ho 10 MHz. Joaloka theknoloji e tsoetseng pele ea ho sebetsana le lijo, ultrasound e na le litšobotsi tsa ketso e bonolo le pertinence e matla. E sebelisoa haholo lijong le masimong a mang 'me e na le litebello tse kholo tsa nts'etsopele.
Ho ea ka maqhubu le matla a maqhubu a ultrasonic, maqhubu a ultrasonic a ka aroloa ka mekhahlelo e 'meli: maqhubu a matla a tlaase a matla a tlaase le a tlaase a matla a phahameng-frequency ultrasonic maqhubu. Har'a bona, matla a phahameng a tlaase a maqhubu a ultrasound (khafetsa pakeng tsa 20 le 100 kHz) e boetse e tsejoa e le matla a ultrasound, a nang le mefuta e mengata ea likopo tsa ho sebetsana le lijo, tse kang ho khothalletsa emulsification, lisele tse senyang, sterilization le ho bolaea enzyme, ho nolofatsa nama le ho fetola lintho, joalo-joalo. Low-power high-frequency ultrasound (maqhubu a eona a haholo-holo a tsepamisitsoe ho 100 kHz ho 10 MHz) ha e sebelisoe feela ho hlahlojoa ke bongaka, empa hape e sebelisoa haholo ho hlahloba le ho hlahloba thepa ea lijo tsa 'mele le lik'hemik'hale, tse kang boima, kholo, tsoekere, acidity, joalo-joalo.
