Sonography. Gịnị ka ọ bụ na ihe bụ ihe ndabere nke nyocha usoro

Mgbe a dibịa na-ezo onye ọrịa na ultrasound, ọtụtụ ajụjụ na-adịghị na-emekarị na-ebilite. Ma ọ bụrụ na nhọpụta nke eji omimi okwu "ultrasound", ajụjụ agbapụtara ka peas. Ya mere, ọ dị mkpa ịghọta, sonography - ihe ọ bụ? Na ụfọdụ, onye ọrịa na-nyere a yiri ọrụ.

The mbụ ndidi mkpakọrịta jikọrọ-ehi ụra, ma ultrasound nwere ihe ọ bụla na-eme na ya. Ultrasound na sonography - aha dị iche iche maka otu usoro. N'ihi otu nnyocha mgbe ụfọdụ na-eji aha nke sonography. Dabere na nke a, anyị nwere ike a dị mfe ọgwụgwụ: ultrasound, ultrasound, ultrasound - ihe ọ bụ? Nke a ultrasound-arụpụta ntule nke morphological na ọtọ kwa nke akụkụ na ụmụ mmadụ arọ.

On ihe bụ usoro

Ultrasound usoro dabeere na atụmatụ nke ultrasonic ebili mmiri ebe ahu Agbaghara. Na nke ọ bụla ndu ozu iso nke anụ ahụ nke dị iche iche njupụta na-eguzogide.

Nke ahụ bụ n'ezie a ndekọ nke ultrasound nkuzi mgbamejije n'ókè gosipụtara si akpọkwa.

Medical ngwa maka ultrasound (sonography) eji a ugboro ole nke 1.5 na 29 MHz. The kacha pitch na ike ga-aghọta ha site mmadụ ntị, 20 kHz. Ihe oyiyi - bụghị naanị ndị ngwe nke esịtidem ngwa ma ọ bụ ọkpụkpụ òkè dị ka x-ụzarị, na nkewa nke esịtidem owuwu.

Brief nkọwa nke ultrasound igwe

Kụziere nnyocha e mere iji ọgwụ ultrasound igwe. Sonography - ihe ọ bụ? Ma niile ngwaọrụ bụ otu? Gịnị bụ ọcha ha iso nke? Ihe kacha mma na ngwaọrụ ultrasound ngwa nwere ike ịghọta physics. Ha na-aghọta ihe bụ piezoelectric mmetụta, ọfiọkde ogologo, vibrations na frequencies. Nkịtị ndidi iji mara na ngwaọrụ mejupụtara ndị na-esonụ ihe:

• a generator nke ultrasonic mmiri na ebili mmiri, i.e. usu generator emitting na n'out oge na-anata gosipụtara n'ókè;
• ultrasonic mmetụta-transdyusora, nke ụlọ a ọnụ ọgụgụ buru ibu nke pezokristallicheskih transducers na mmetụta e nwere a na-elekwasị anya oghere na-enye gị na-elekwasị anya na chọrọ omimi.

Ụdị transdyusorov (mmetụta)

The mbụ nkewa a rụrụ na n'ibu na kọmputa ngwaọrụ. Ịgụ isiokwu n'ibu ihe mmetụta na rụrụ site ije nke radiant mmewere (adiana ma ọ bụ Mkpatụ). Isi drawback - ala mkpebi foto, vibration na ụzụ ọrụ. Modern ultrasound sonography ịhapụ ihe mgbe ochie nlereanya, na-ahọrọ na-eji kọmputa version.

Kọmputa sensọ ndị ọzọ oge a na akụrụngwa. Iṅomi oyiyi emepụta site electronic n'aka. The ndise bụ ihe doro anya na zuru ezu. Noise na vibration mgbe na-arụ ọrụ ngwá ọrụ na-anọghị.

Ultrasonic ịgụ isiokwu a na-ekewa a linear, convex na mpaghara ụdị. N'ihi ya, etinyere 3 iche iche nke sensọ:

1. Linear. Ọ na-eji a ugboro ole nke 5-15 MHz. Ndapụta oyiyi mpaghara nyochaworo na elu mkpebi oyiyi, ngwa uru kwekọrọ na obosara nke mmetụta, ma omimi scanning nke karịa 11 cm. Ọ bụ ike inye a dịgasị edo kọntaktị mmetụta nweta a elu àgwà image. Eji na-iṅomi thyroid, ara, na-ajụ-sized nkwonkwo na muscle anụ ahụ.
2. Convex. 1,9-7,5 MHz ugboro. Ịgụ isiokwu elu nke nta ogologo karịa akara mmetụta. Ana achi achi a uko edo kọntaktị na akpụkpọ. Enye a warara picture, dịtụ hịkọsịrị size, ma nnyocha omimi 25 cm. A na-eji maka nnyocha nke abdominal uji eze na retroperitoneal, urogenital usoro, nnukwu nkwonkwo (hip, n'ihi na ihe atụ).
3. Sector. Ọ na-eji a ugboro ole nke 1.5-5 MHz. Image ibu n'ezie. Ọ na-enye ike na-iṅomi na a oké omimi. Ọtụtụ mgbe na-eji maka echocardiography.

Dị iche iche nke sensọ eji enyocha abdominal akụkụ, obi, thyroid, ara, spain na nkwonkwo. Ke adianade do, e nwere microsensors maka endoscopy na biopsy agịga.
