APAKAH MAKSUD MICROBUBBLES dalam CORSICA?
Microbubbles
Microbubbles adalah gelembung yang lebih kecil daripada diameter satu milimeter, tetapi lebih besar daripada satu mikrometer. Ia digunakan dalam diagnostik perubatan sebagai agen kontras untuk pengimejan ultrasound. Gas yang dipenuhi, mis. udara atau perfluorokarbon, mikroba berayun dan bergetar apabila medan tenaga sonik digunakan dan mungkin mencerminkan gelombang ultrasound. Ini membezakan microbubbles dari tisu sekeliling. Dalam praktiknya, kerana gelembung gas dalam cecair kekurangan kestabilan dan oleh itu dengan cepat membubarkan, mikroba harus dikemas dengan kulit keras. Cangkang diperbuat daripada lemak atau protein seperti Optison microbubbles yang terdiri daripada gas perfluoropropane yang dikemas dalam shellum serum albumin. Microbubbles boleh digunakan untuk penghantaran dadah, penyingkiran biofilm dan tujuan rawatan air / air sisa. Mereka juga dihasilkan oleh pergerakan badan kapal melalui air, mewujudkan lapisan gelembung; ini boleh mengganggu penggunaan sonar kerana kecenderungan lapisan menyerap atau mencerminkan gelombang bunyi.
Definisi microbubbles dalam kamus Corsica
Definisi microbubbles dalam kamus adalah medium kontras yang digunakan dengan ultrasound, yang terdiri daripada gelembung kecil gas yang diperkenalkan ke dalam sistem vaskular atau tiub Fallopian untuk meningkatkan imej-imej yang diperolehi.
