Izinhlobo ezintathu ezivame kakhulu zama-probe (ezibuye zibizwe ngokuthi ama-ultrasonic transducers) ziwumugqa, ziyi-convex, nezigaba ezinezigaba.I-linear near-field resolution yinhle futhi ingasetshenziselwa ukuhlola imithambo yegazi.I-convex surface ivumela ukuhlolwa okujulile, okungasetshenziselwa ukuhlolwa kwesisu nokunye.Uhlu olunezigaba lunonyawo oluncane kanye nemvamisa ephansi, engasetshenziselwa ukuhlolwa kwenhliziyo, njll.
Inzwa yomugqa
Amakristalu e-piezoelectric ahlelwe ngokulandelana, umumo we-beam unonxande, futhi ukulungiswa kwensimu eseduze kuhle.
Okwesibili, imvamisa nokusetshenziswa kwama-transducer alayini kuncike ekutheni umkhiqizo usetshenziselwa ukuthwebula kwe-2D noma kwe-3D.Ama-linear transducer asetshenziselwa ukuthwebula kwe-2D agxile ku-2.5Mhz – 12Mhz.
Ungasebenzisa le nzwa kuzinhlelo zokusebenza ezahlukahlukene ezifana: ukuhlolwa kwemithambo, i-venipuncture, ukubonwa kwemithambo, i-thoracic, i-thyroid, i-tendon, i-arthogenic, i-intraoperative, i-laparoscopic, i-photoacoustic imaging, i-ultrasound velocity change imaging.
Ama-transducer alayini wesithombe se-3D anemvamisa emaphakathi engu-7.5Mhz – 11Mhz.
Ungasebenzisa lesi siguquli: isifuba, i-thyroid, i-vascular application carotid.
Inzwa ye-Convex
Ukulungiswa kwesithombe se-Convex probe kuncipha njengoba ukujula kukhuphuka, futhi imvamisa yaso nokusebenza kuncike ekutheni umkhiqizo usetshenziselwa ukuthwebula kwe-2D noma kwe-3D.
Isibonelo, ama-convex transducer wesithombe se-2D anemvamisa emaphakathi engu-2.5MHz - 7.5MHz.Ungayisebenzisela: ukuhlolwa kwesisu, ukuhlolwa kwe-transvaginal kanye ne-transrectal, ukuxilongwa kwezitho.
I-convex transducer yesithombe se-3D inendawo yokubuka ebanzi kanye nemvamisa emaphakathi engu-3.5MHz-6.5MHz.Ungayisebenzisela ukuhlolwa kwesisu.
Inzwa ye-Phased Array
Le transducer, eqanjwe ngemuva kokuhlelwa kwamakristalu e-piezoelectric, ebizwa ngokuthi i- phased array, iyikristalu evame ukusetshenziswa kakhulu.I-beam spot yayo incane kodwa iyanwebeka ngokuya ngobuningi bohlelo lokusebenza.Ngaphezu kwalokho, umumo we-beam ucishe ube ngunxantathu futhi ukulungiswa kwensimu eseduze kubi.
Singayisebenzisela: izivivinyo zenhliziyo, okuhlanganisa izivivinyo ze-transesophageal, izivivinyo zesisu, izivivinyo zobuchopho.
