INDLELA YOKUKHETHA I-TRANSDUCER ELUNGILEYO KWI-SCANNER ULTRASOUND?

Ukusebenza kakuhle kweisixhobo sokuskenaubukhulu becala kuxhomekeke kwi-ultrasound sensors ezifakwe kuyo.Inani labo kwisixhobo esinye sokuskena linokufikelela kumaqhekeza angama-30.Ziziphi izinzwa, zenzelwe ntoni kwaye zikhethwa njani ngokuchanekileyo - makhe sijonge ngakumbi.

IINTLOBO ZEZIMVA ZE-ULTRASONIC:

• i-linear probes isetyenziselwa ukuxilongwa kwezakhiwo kunye namalungu angekho nzulu.I-frequency abasebenza kuyo yi-7.5 MHz;
• I-convex probes isetyenziselwa ukuxilonga izicubu ezinzulu kunye namalungu.I-frequency apho i-sensor ezinjalo zisebenza khona ngaphakathi kwe-2.5-5 MHz;
• i-microconvex sensors - ububanzi besicelo sabo kunye nokuphindaphinda apho basebenza khona kufana neentlobo ezimbini zokuqala;
• izinzwa ze-intracavitary - ezisetyenziselwa i-transvaginal kunye nezinye izifundo ze-intracavitary.Ukuskena kwabo rhoqo yi-5 MHz, ngamanye amaxesha aphezulu;
• i-biplane sensors isetyenziselwa ikakhulu ukuxilongwa kwe-transvaginal;
• i-intraoperative sensors (i-convex, i-neurosurgical kunye ne-laparoscopic) isetyenziswa ngexesha lotyando;
• i-invasive sensors - ezisetyenziselwa ukuxilonga imithambo yegazi;
• i-ophthalmic sensors (i-convex okanye icandelo) - isetyenziswe kwisifundo se-eyeball.Basebenza rhoqo kwi-10 MHz okanye ngaphezulu.

UMGAQO WOKUKHETHA IMIBONO YE-ULTRASOUND SCANNER

Kukho iintlobo ezininzi ezahlukeneyoIinzwa ze-ultrasonic.Zikhethwa ngokuxhomekeke kwisicelo.Kukwathathelwa ingqalelo iminyaka yesifundo.Ngokomzekelo, ii-sensor ze-3.5 MHz zifanelekile kubantu abadala, kwaye kwizigulane ezincinci, i-sensor zohlobo olufanayo zisetyenziswa, kodwa kunye ne-frequency ephezulu yokusebenza - ukusuka kwi-5 MHz.Ukuxilongwa okucacileyo kwe-pathologies yengqondo yeentsana ezisanda kuzalwa, izinzwa zecandelo ezisebenza ngokuphindaphindiweyo kwe-5 MHz, okanye i-microconvex ephezulu-frequency sensors isetyenziswa.

Ukufundisisa izitho zangaphakathi ezibekwe nzulu, iisenso ze-ultrasound zisetyenziswa , ezisebenza ngokuphindaphindiweyo kwe-2.5 MHz, kunye nezakhiwo ezinzulu, i-frequency kufuneka ibe ubuncinane be-7.5 MHz.

Iimviwo zenhliziyo zenziwa ngokusebenzisa i-ultrasonic sensors exhotyiswe nge-antenna enezigaba kwaye isebenza ngokuphindaphindiweyo ukuya kwi-5 MHz.Ukuxilonga intliziyo, kusetyenziswa izinzwa ezifakwe kummizo.

Uphononongo lwengqondo kunye neemviwo ze-transcranial zenziwa ngokusebenzisa i-sensor, i-frequency yokusebenza i-2 MHz.Iinzwa ze-Ultrasound zisetyenziselwa ukuhlola izono ze-maxillary, kunye ne-frequency ephezulu - ukuya kwi-3 MHz.
