Gusuzuma Ultrasonic
Igikoresho cyo kwisuzumisha ultrasonic nigikoresho cyubuvuzi gihuza ihame rya sonar nubuhanga bwa radar mugukoresha amavuriro.Ihame shingiro nuko ultrasonic pulse yumurongo mwinshi irasa mubinyabuzima, kandi imiterere itandukanye igaragarira mubice bitandukanye mubinyabuzima kugirango ikore amashusho.Kugirango rero umenye niba hari ibisebe mubinyabuzima.Igikoresho cyo kwisuzumisha ultrasonic cyateye imbere kuva umwimerere umwe wa ultrasonic scanning yerekanwe kugeza kuri bibiri-bitatu-bitatu na bine-bine bya ultrasonic scanning no kwerekana, byongera cyane amakuru ya echo kandi bigatuma ibikomere mumubiri wibinyabuzima bisobanuka kandi byoroshye kuri gutandukanya.Kubwibyo, bizarushaho gukoreshwa cyane mubikoresho byo gupima ultrasonic.
1. Icyerekezo kimwe cya ultrasonic scanning no kwerekana
Mu bikoresho byo gusuzuma ultrasonic, abantu bakunze kuvuga ubwoko bwa A na Type M, basuzumwa na tekinoroji ya ultrasonic pulse-echo intera yo gupima intera, nk'ikizamini kimwe cya ultrasonic.Icyerekezo cyubwoko bwimyuka ya ultrasonic ntigihinduka, kandi amplitude cyangwa ibara ryikigereranyo cyikimenyetso kigaruka inyuma uhereye kumurongo utari icyarimwe icyarimwe uratandukanye.Nyuma ya amplification, irerekanwa itambitse cyangwa ihagaritse kuri ecran.Ubu bwoko bwishusho bwitwa ultrasonic image imwe.
(1) Andika A ultrasound scan
Probe (transducer) ukurikije umwanya wa probe, muburyo butajegajega kumubiri wumuntu kugirango isohore megahertz ultrasonic wave, binyuze mumubiri wumuntu echo yibitekerezo no kwongera imbaraga, hamwe na echo amplitude hamwe nimiterere kuri ecran ya ecran.Uhagaritse guhuza ibikorwa byerekana amplitude waveform ya echo yerekana;Hariho umwanya nintera kuri abscissa.Ibi birashobora gushingira kumwanya wa echo, echo amplitude, imiterere, umubare wumuraba hamwe namakuru ajyanye na lesion hamwe na anatomique yumwanya wo gusuzuma.A - andika ultrasonic probe mumwanya uhamye urashobora kubona spekiteri.
(2) M-ubwoko bwa ultrasound scaneri
Probe (transducer) yanduza kandi yakira urumuri rwa ultrasonic kumubiri mumwanya uhamye no mu cyerekezo.Igiti gihindura umucyo wa vertical scan umurongo werekanwe unyuze mubimenyetso bya echo byubujyakuzimu butandukanye, kandi bikaguka mugihe gikurikiranye, bigakora igishushanyo mbonera cyerekana urujya n'uruza rwa buri ngingo mumwanya umwe mugihe.Ubu ni M-ultrasound.Birashobora kandi kumvikana nka: M-moderi ultrasound nigishushanyo mbonera cyumurongo wigihe cyimpinduka kumwanya wimbitse utandukanye icyerekezo kimwe.M - scan ya sisitemu irakwiriye cyane cyane gusuzuma ibinyabiziga.Kurugero, mugusuzuma umutima, ibipimo bitandukanye byimikorere yumutima birashobora gupimwa kumurongo werekana ibishushanyo, so m-ultrasound.Bizwi kandi nka echocardiography.
2. Ibice bibiri-ultrasonic scanning no kwerekana
Kuberako isuzuma rimwe rishobora gusuzuma gusa ingingo zabantu ukurikije amplitude yo kugaruka kwa ultrasonic kugaruka hamwe nubucucike bwa echo mubishushanyo, ultrasound imwe-imwe (ubwoko bwa ultrasound) igarukira cyane mugupima kwa ultrasonic.Ihame rya ultrasonic scanning yerekana amashusho ni ugukoresha ultrasonic pulse echo, guhinduranya urumuri rwibice bibiri byerekana imvi, byerekana neza amakuru yigice cyumubiri wumuntu.Sisitemu ebyiri-yogusikana ituma transducer mumubiri wumuntu muburyo butajegajega imbere muri probe yatangije ultrasound ya MHZ nyinshi, kandi kumuvuduko runaka mumwanya wibice bibiri, aribyo byapimwe kumwanya wibice bibiri, hanyuma byoherezwa nyuma yumuntu umubiri kugirango wongere ibimenyetso bya echo gutunganya kugirango werekane cathode cyangwa kugenzura kuri gride, kwerekana urumuri rwumucyo uhinduka hamwe nubunini bwikimenyetso cya echo, Hakozwe ishusho ya tomografi ebyiri.Iyo yerekanwe kuri ecran, ordinate yerekana igihe cyangwa ubujyakuzimu bwijwi ryijwi mumubiri, mugihe umucyo uhindurwa na amplitude ya ultrasonic echo kumwanya uhuye, naho abcissa igereranya icyerekezo cyijwi ryerekana scan umubiri w'umuntu.
