CE ÎNSEAMNĂ MICROBUBBLES ÎN ENGLEZĂ?
microbule
Microbubliile sunt bule mai mici de un milimetru în diametru, dar mai mari de un micrometru. Ele sunt utilizate în diagnosticarea medicală ca agent de contrast pentru imagistica cu ultrasunete. Gazul umplut, de ex. aer sau perfluorocarbon, microbublitele oscilează și vibrează atunci când se aplică un câmp de energie sonică și pot reflecta undele ultrasunete. Aceasta distinge microbulele de țesuturile din jur. În practică, deoarece bulele de gaze din lichid nu au stabilitate și, prin urmare, se vor dizolva rapid, microbubblele trebuie încapsulate cu o cochilie solidă. Carcasa este făcută fie dintr-o lipidă, fie dintr-o proteină cum ar fi microbubliile Optison care constau din gaz perfluorpropan încapsulat de o coajă de albumină serică. Microbubliile pot fi utilizate pentru livrarea de medicamente, îndepărtarea biofilmelor și tratarea apei / apei reziduale. Acestea sunt, de asemenea, produse prin mișcarea corpului unei nave prin apă, creând un strat de bule; acest lucru poate interfera cu utilizarea sonarului datorită tendinței stratului de a absorbi sau reflecta undele sonore.
Definiția microbubbles în dicționarul Engleză
Definiția microbublinelor din dicționar este un mediu de contrast folosit cu ultrasunete, care constă în mici bule de gaz introduse în sistemul vascular sau în tuburi Fallopian pentru a îmbunătăți imaginile obținute.
