Ukuhlelwa kwe-ultrasound eqhelekileyo yokusetyenziswa kwezilwanyana

Izixhobo zeA-Ultrasound ziqhele ukusetyenziswa kwiifama zeehagu, ngakumbi kwiifama zokufuya, ezinokusetyenziswa ukulinganisa ukukhulelwa, umqolo, izihlunu zamehlo, kunye nezinye izixhobo zokugxotha iintaka kunye nezilwanyana nazo zisetyenziswa kwi-ultrasound.Unokusebenzisa rhoqo izixhobo ze-ultrasound, kodwa ungazi ezinye zolwazi olufanelekileyo, eli nqaku luphononongo olulula lwetekhnoloji ye-ultrasound esetyenziswa kwiifama zeehagu.

Ultrasound
I-Ultrasound yi-high-frequency sound wave, uluhlu lwendlebe yomntu ukuva i-wave yesandi yi-20Hz ukuya kwi-20KHz, ngaphezu kwe-20KHz (i-vibration 20 amawaka amaxesha ngesekhondi) i-wave yesandi ingaphaya koluhlu lokuva komntu unokuva, ngoko ke. ibizwa ngokuba yi-ultrasound.
Izandi zesandi ezisetyenziswa zizixhobo ze-ultrasound ziphezulu kakhulu kune-20KHz, njengokuphindaphindwa kwe-electronic convex array ultrasound pregnancy scanner yi-3.5-5MHz.
Isizathu sokuba kutheni i-ultrasound iya kusetyenziselwa ukufumanisa izixhobo ikakhulu ngenxa yokuqondisa kwayo okulungileyo, ukubonakaliswa okunamandla, kunye nokukwazi ukungena.Undoqo wezixhobo ze-ultrasound yi-transducer, eguqula imiqondiso yombane ibe ngamaza e-ultrasound ukuba akhutshwe, kwaye amaza e-ultrasound abonakaliswe ngasemva afunyanwa yi-transducer, aguqulwa abe yimiqondiso yombane, kwaye imiqondiso yombane iphinda iqwalaselwe ukwenza imifanekiso okanye izandi.

I-ultrasound

Ekubeni i-motor rotation frequency inomda ophezulu, i-B-ultrasound yeprobe yomatshini iya kuba nomda wokucaca.Ukuze ufumane isisombululo esiphezulu, iiprobe ze-elektroniki zenziwe.Endaweni yokusebenzisa i-transducer eqhutywa ngoomatshini ukujinga, iprobe ye-elektroniki ibeka inani le-"A-ultrasound" (iiflashlights) kwimilo yeconvex, nganye ebizwa ngokuba yi-array element.Ikhoyo ngoku elawulwa yi-chip ikhupha uluhlu ngalunye ngokulandelelana, ngaloo ndlela ifumana isignali ekhawulezayo yokuthumela kunye nokufumana i-frequency kune-probe yomatshini.

Kodwa ngamanye amaxesha uya kufumanisa ukuba ezinye ii-electronic convex array probes zinomgangatho wokucinga ombi ngakumbi kuneprobe zoomatshini ezilungileyo, ezibandakanya inani loluhlu, oko kukuthi, zingaphi ii-arrays ezisetyenziswa kunye, 16?32 kubo?64 kubo?128Izinto ezingakumbi, kokukhona umfanekiso ucace ngakumbi.Ngokuqinisekileyo, ingqikelelo yenombolo yetshaneli iyabandakanyeka.

Ngaphaya koko, uya kufumanisa ukuba nokuba ngaba iprobe yoomatshini okanye i-electronic convex array probe, umfanekiso licandelo.Umfanekiso okufutshane umncinci, kwaye umfanekiso okude uya kwandiswa.Emva kokuphazamiseka kokuthumela kunye nokufumana izibonakaliso phakathi kwezinto ezicwangcisiweyo zoyiswa ngokobuchwephesha, izinto zoluhlu zinokuthi zifakwe kumgca ochanekileyo, kwaye i-electronic linear array probe yenziwa.Umfanekiso weprobe yoluhlu lwe-elektroniki sisikwere esincinci, njengefoto.Ngoko ke, xa usebenzisa i-linear array probes ukulinganisa i-backfat, isakhiwo se-lamellar esinemigangatho emithathu ye-backfat sinokuboniswa ngokugqibeleleyo.

Ngokwenza i-probe ye-linear ye-linear ibe nkulu kancinane, ufumana i-eye muscle probe.Inokukhanyisa yonke imisipha yamehlo, kwaye ngokuqinisekileyo, ngenxa yexabiso eliphezulu lesixhobo, isoloko isetyenziselwa ukuzala.

Ngaba kukho i-C-ultrasounds kunye ne-D-ultrasounds?
Akukho C-ultrasounds, kodwa kukho D-ultrasounds.D ultrasound nadoppler ultrasound, kusetyenziso lwedumgaqo oppler of ultrasound.Siyazi ukuba isandi sine adisiphumo oppler, nto leyo xa uloliwe edlula phambi kwakho, isandi uya ngokukhawuleza kwaye emva koko kancinci.Ukusebenzisadumgaqo oppler kaThixo, unako ukukwazisa ukuba kukho into ehamba ngakuwe okanye kude kuwe.Ngokomzekelo, xa usebenzisa i-ultrasound ukulinganisa ukuhamba kwegazi, imibala emibini ingasetyenziselwa ukuphawula ukuhamba kwegazi, kwaye ubunzulu bombala busetyenziselwa ukubonisa ukuhamba kwegazi.Oku kubizwa ngokuba yi-ultrasound yombala.

Umbala we-ultrasound kunye nombala wobuxoki
Kukho abantu abaninzi abathengisa i-B-ultrasound baya kubhengeza ukuba iimveliso zabo ziyi-ultrasound yombala.Ngokucacileyo hayi i-ultrasound yombala (i-D-ultrasound) ebesithetha ngayo kwisiqendu sangaphambili.Oku kunokubizwa ngokuba ngumbala womgunyathi.Umgaqo ufana nomabonwakude omnyama nomhlophe kunye nomgca wefilimu yombala.Inqaku ngalinye kwi-B-ultrasound limele ubunzulu bomqondiso obonakalisiweyo kulo mgama, obonakaliswe kwi-gray scale, ngoko ke umbala ufana ngokufanayo.

A-ultrasoundinokuthelekiswa nekhowudi enye-dimensional (ikhowudi yebha);I-B-ultrasound inokuthelekiswa nekhowudi ye-two-dimensional, kunye nombala wobuxoki B-ultrasound ipeyintiwe ikhowudi ye-dimensional;D-ultrasoundinokuthelekiswa nekhowudi enemigangatho emithathu.
