Ezona ntlobo zintathu zixhaphakileyo zeprobe (ezikwabizwa ngokuba zii-ultrasonic transducers) zi-linear, convex, kunye ne-pased array.Isisombululo esikufutshane nebala silungile kwaye singasetyenziselwa ukuhlolwa kwemithambo yegazi.Umphezulu we-convex ulungele uviwo olunzulu, olungasetyenziselwa ukuhlolwa kwesisu kunye nokunye.Uluhlu olunezigaba lunonyawo oluncinci kunye ne-frequency ephantsi, engasetyenziselwa iimviwo zenhliziyo, njl.
Uluvo lomgca
Iikristale ze-piezoelectric zicwangciswe ngokulandelelana, ubume be-beam buxande, kwaye isisombululo esikufutshane sendawo silungile.
Okwesibini, ukuphindaphinda kunye nokusetyenziswa kwee-transducers zemigca kuxhomekeke ekubeni imveliso isetyenziselwa i-2D okanye i-3D imaging.Ii-transducers zomgca ezisetyenziselwa ukucinga nge-2D zijoliswe kwi-2.5Mhz - 12Mhz.
Ungasebenzisa le nzwa kwizicelo ezahlukeneyo ezinje: uvavanyo lwemithambo, i-venipuncture, i-vascular visualization, i-thoracic, i-thyroid, i-tendon, i-arthogenic, i-intraoperative, i-laparoscopic, i-photoacoustic imaging, i-ultrasound velocity change imaging.
Ii-transducer ze-linear ze-imaging ye-3D zineziko lokujikeleza kwe-7.5Mhz - 11Mhz.
Ungasebenzisa lo mguquli: isifuba, i-thyroid, i-vascular application carotid.
Uluvo lweConvex
Isisombululo somfanekiso weConvex probe siyehla njengoko ubunzulu bukhula, kwaye ukuphindaphindwa kwayo kunye nokusetyenziswa kwayo kuxhomekeke ekubeni imveliso isetyenziselwa i-2D okanye i-3D imaging.
Umzekelo, ii-convex transducers zomfanekiso we-2D zineziko lokujikeleza kwe-2.5MHz - 7.5MHz.Ungayisebenzisela: iimviwo zesisu, iimviwo ze-transvaginal kunye ne-transrectal, ukuxilongwa kwamalungu.
I-convex transducer ye-imaging ye-3D inommandla obanzi wokujonga kunye ne-frequency center ye-3.5MHz-6.5MHz.Ungayisebenzisa kwiimviwo zesisu.
Isivamvo seSigaba seArray
Le transducer, ebizwa emva kolungiselelo lweekristale zepiezoelectric, ezibizwa ngokuba yi-phased array, yeyona crystal isetyenziswa ngokuqhelekileyo.Indawo yayo yomqadi imxinwa kodwa iyanda ngokusetyenziswa rhoqo.Ngaphaya koko, imilo ye-beam iphantse ibe ngunxantathu kwaye isisombululo esikufutshane nebala sibi.
Singayisebenzisela: iimviwo zentliziyo, kubandakanywa iimviwo ze-transesophageal, iimviwo zesisu, iimviwo zengqondo.
