Mokhoa oa ho lokisa sesebelisoa nakong ea tlhahlobo ea ultrasound (ka tlhaloso ea mohato ka mohato - Karolo ea 2)

2.CDFI

Ts'ebeliso ea CDFI: Lekola methapo ea mali, tseba mofuta oa liphaephe,

Ho khetholla methapo le methapo, ho bontša tšimoloho le tataiso ea phallo ea mali,

Mokhahlelo oa nako, o bonts'a mofuta oa phallo ea mali, o bonts'a lebelo la phallo ea mali ka potlako

Boemo bo butle, bo tataisoang ba spectral Doppler sampling

1) Likahare tsa kamehla tsa CDFI (mongolo o mofubelu):

2) CDFI ha se hangata e fetolang litaba

Kakaretso ea phaello:

 

Boholo ba lebokose la mebala le boemo

Phapang ea setšoantšo lipakeng tsa Sekala se holimo haholo, se tlase haholo le se mahareng

Melaetsa ea lisampole ea foreime ea ho kheloha sekhutlo

Ho kheloha ho latela tataiso ea mothapo oa mali ho etsa hore mali a phalle ka har'a lesoba a be a khotsofatse.

Potso ea 1: Mokhoa oa ho lokisa liparamente tsa ultrasound ho bonts'a phallo ea mali e tlase?

1. Eketsa---fumana

2. Fokotsa --- sekala sa lebelo

3. Eketsa --- tlhahiso ya modumo Output Power

4. Eketsa --- foreimi karolelano

6. Fokotsa---sebaka sa sampole

6. Fokotsa --- palo ea lintlha tse tsepamisitsoeng (ho ntlafatsa tsepamiso)

7. Fokotsa --- sebaka

Fokotsa--mohlala oa sebaka sa pontšo:

Potso ea 2: Mokhoa oa ho fokotsa ho tsoa ha 'mala le ho tlosa aliasing?

1. Fokotsa--ho rua

2. Eketsa -- sekala sa lebelo SALE

Potso ea 3: Mokhoa oa ho eketsa sekhahla sa foreimi?

1. Fokotsa --- B mode saese

2. Fokotsa --- botebo

3. Fokotsa --- foreimi ea sampole ea mebala

4. Fokotsa --- foreimi karolelano

5. Fokotsa --- palo ea lintlha tse tsepamisitsoeng maikutlo

6. Fokotsa --- sebaka sa ho lemoha

3. Mokhoa oa ho fetola Doppler ea Spectral

1. Mokhoa oa ho sebetsa: Haeba tekanyo ea phallo e sa phahame, khetha PW, haeba tekanyo ea phallo e phahame, khetha CW.

2. Maemo a sefe: Sefa se tlaase-tlaase se sebelisetsoa ho phalla ha mali ka lebelo le tlaase, 'me sefa se phahameng se sebelisetsoa ho phalla ha mali ka lebelo le phahameng.

3. Sekala sa lebelo: Khetha sekhahla sa lebelo se tsamaellanang le lebelo la phallo ea mali e bonoang.

4. Monyako oa sampling: lemoha methapo ea mali, sampuli ea monyako ≤ methapo ea mali ka hare ho bophara.Sheba li-valve tsa intracardiac

Lemati la sampuli ea molomo le boholo bo mahareng.

5. Zero baseline: ho tsamaisa motheo ho ka eketsa sebaka sa tekanyo ka tsela e itseng mme ho qoba liphoso.

Hona joale e hloekisitsoe.

6. Letšoao la ho feto-fetoha ha maqhubu le ea holimo le tlase: ho bonolo ho lekanya, sesebelisoa se koahela sebopeho sa maqhubu a maqhubu.

7. Lehlakore la ketsahalo: tlhahlobo ea pelo ≤ 20, methapo ea mali ea peripheral ≤ 60, le angle e lokela ho lokisoa.

8. Khafetsa ea phetisetso: Leqhubu le phahameng le sebelisoa bakeng sa phallo ea mali e tlaase, 'me lebelo le tlaase le sebelisetsoa ho phalla ha mali ka lebelo le phahameng.

Hangata PW e lokisa litaba

Mohlala oa boholo ba monyako

1. Ha lemati la sampling le le moqotetsane, ho na le phapang e fokolang ka lebelo la phallo pakeng tsa lihlopha tse haufi, "vt" curve e moqotetsane, 'me fensetere e kholo.

2. Ha lemati la sampuli le koahela lumen eohle, fensetere e "tlatsitsoe ka ho feletseng"

Potso ea 5: Mokhoa oa ho Eketsa kutloisiso ea PW&CW

1. Eketsa phaello

2. Eketsa tlhahiso ea molumo

3. Eketsa molumo oa sampole

4. Beha angle ea ho hlahloba ka nepo

Tlhokomeliso: Lisebelisoa tsa Ultrasound li na le maemo a behiloeng esale pele 'me li loketse ho hlahloba litho le lisele tse fapaneng.
