Ụkpụrụ nke onyonyo fotoacoustic

Photoacoustic Imaging (PAI) bụ usoro onyonyo onyonyo nke jikọtara ọnụngwa anyana acoustics ka n'ịwa ultrasonic mgbaàmà iji mmekọrịta nkeìhèna anụ ahụ iji nweta ihe oyiyi anụ ahụ dị elu. A na-eji ya n'ọtụtụ ebe na mpaghara biomedical, karịsịa n'ịchọpụta etuto, onyonyo vaskụla, onyonyo akpụkpọ ahụ na mpaghara ndị ọzọ.

Ụkpụrụ:
1. Ntinye ọkụ na mgbasawanye ọkụ: - Foto fotoacoustic na-eji mmetụta ọkụ na-emepụta site na ntinye ọkụ. Mkpụrụ ndụ pigmenti dị n'ime anụ ahụ (dịka, hemoglobin, melanin) na-amịkọrọ photons (na-adịkarị nso ọkụ infrared), nke na-agbanwe ghọọ ike okpomọkụ, na-eme ka okpomọkụ dị n'ógbè ahụ bilie.
2. Mgbasa ọkụ na-akpata ultrasound: - Mmụba okpomọkụ na-eduga na ntanye mgbasawanye nke anụ ahụ, nke na-emepụta ebili mmiri nrụgide (ie ultrasound).
3. Nchọpụta ultrasonic: - ebili mmiri ultrasonic emepụtara na-agbasa n'ime anụ ahụ, a na-enwetakwa akara ngosi ndị a ma dekọọ ya site na ultrasonic sensọ (dị ka nyocha ultrasonic).
4. Mweghachi ihe oyiyi: A na-agbakọ ihe mgbaàmà ultrasonic anakọtara ma hazie ya iji wughachi ihe owuwu na ihe oyiyi ọrụ nke anụ ahụ, nke nwere ike inye njirimara absorption anya nke anụ ahụ. Uru nke onyonyo fotoacoustic: Ntugharị dị elu: Foto fotoacoustic na-adabere na njirimara absorption nke anụ ahụ, na anụ ahụ dị iche iche (dịka ọbara, abụba, akwara, wdg) nwere ikike dị iche iche iji nweta ìhè, ya mere ọ nwere ike inye ihe oyiyi dị elu. Mkpebi dị elu: N'iji mkpebi dị elu nke ultrasound, fotoacoustic imaging nwere ike nweta milimita ma ọ bụ ọbụna ihe onyonyo sub-millimeter ziri ezi. Ndị na-adịghị emerụ ahụ: Foto fotoacoustic bụ ihe na-adịghị mma, ìhè na ụda agaghị emebi anụ ahụ, dị mma maka nchọpụta ahụike mmadụ. Ikike onyonyo omimi: E jiri ya tụnyere onyonyo ọdịnala ọdịnala, onyonyo fotoacoustic nwere ike banye ọtụtụ centimita n'okpuru akpụkpọ ahụ, nke dabara maka onyonyo anụ ahụ miri emi.

Ngwa:
1. Vascular imaging: – Photoacoustic imaging nwere ike ịchọpụta ìhè-absorbing Njirimara nke hemoglobin n'ime ọbara, n'ihi ya, ọ nwere ike na-egosipụta n'ụzọ ziri ezi na Ọdịdị na oxygenation ọnọdụ nke ọbara arịa maka nlekota microcirculation na ikpe ọrịa.
2. Nchọpụta Tumor: - Angiogenesis na anụ ahụ tumor na-abụkarị nke ukwuu, na fotoacoustic imaging nwere ike inyere aka ịchọpụta etuto n'oge site n'ịchọpụta ihe na-adịghị mma na nhazi vaskụla.
3. Onyonyo na-arụ ọrụ: - Foto fotoacoustic nwere ike nyochaa ikuku oxygen nke anụ ahụ site n'ịchọpụta ntinye nke oxygenation na deoxyhemoglobin n'ime anụ ahụ, nke dị oke mkpa maka nlekota ọrụ nke ọrịa dịka ọrịa cancer na ọrịa obi.
4. Skin imaging: - N'ihi na fotoacoustic imaging na-enwe mmetụta nke ukwuu na elu anụ ahụ, ọ na-adabara n'oge nchọpụta nke akpụkpọ cancer na nyocha nke akpụkpọ abnormalities.
5. Ihe onyonyo nke ụbụrụ: Foto fotoacoustic nwere ike nweta ozi nrịba ọbara nke ụbụrụ n'ụzọ na-adịghị emerụ ahụ maka ọmụmụ ọrịa ụbụrụ dị ka ọrịa strok na epilepsy.

Ihe ịma aka na ntụzịaka mmepe nke onyonyo fotoacoustic:
Isi iyi ọkụnhọrọ: Light ntinye nke dị iche iche wavelengths dị iche iche, otú ịhọrọ ezi wavelength itule mkpebi na penetration omimi bụ ihe ịma aka. Nhazi mgbaàmà: Nnweta na nhazi nke ultrasonic mgbaàmà chọrọ ngwa ngwa na nke ziri ezi algọridim, na mmepe nke ihe oyiyi nwughari technology dịkwa oké mkpa. Multimodal imaging: Enwere ike ijikọ ihe onyonyo fotoacoustic na usoro onyonyo ndị ọzọ (dịka MRI, CT, imaging ultrasound) iji nyekwuo ozi biomedical zuru oke.

Ihe onyonyo fotoacoustic bụ teknụzụ ọhụụ na-arụ ọrụ biomedical nke na-arụ ọrụ dị iche iche, nke nwere njirimara nke ọdịiche dị elu, mkpebi dị elu na enweghị mgbagha. Site na mmepe nke teknụzụ, onyonyo fotoacoustic nwere atụmanya ngwa sara mbara na nyocha ahụike, nyocha ihe ọmụmụ ihe ndụ, mmepe ọgwụ na mpaghara ndị ọzọ.
