Amahame yo gufata amashusho

Amashusho ya Photoacoustic (PAI) ni tekinike yo kuvura yubuvuzi ihuzaoptiquena acoustics kubyara ibimenyetso bya ultrasonic ukoresheje imikoranire yaurumurihamwe na tissue kugirango ubone amashusho yimyenda ihanitse. Ikoreshwa cyane mubice byubuzima, cyane cyane mugutahura ibibyimba, gufata imitsi, gufata amashusho kuruhu nizindi nzego.

Ihame:
1. Kwinjiza urumuri no kwaguka k'ubushyuhe: - Amashusho ya Photoacoustic akoresha ingaruka zumuriro zatewe no kwinjiza urumuri. Molekile ya pigment iri mu ngingo (urugero, hemoglobine, melanin) ikurura fotone (ubusanzwe hafi yumucyo utagira urumuri), ihinduka imbaraga zubushyuhe, bigatuma ubushyuhe bwaho buzamuka.
2. Kwiyongera k'ubushyuhe bitera ultrasound: - Kwiyongera k'ubushyuhe biganisha ku kwaguka gukabije k'ubushyuhe bw'umubiri, butanga imiraba y'umuvuduko (ni ukuvuga ultrasound).
3. Gutahura Ultrasonic: - Imiraba ya ultrasonic yakozwe ikwirakwira mu ngingo, kandi ibyo bimenyetso byakiriwe hanyuma bikandikwa na sensor ya ultrasonic (nka ultrasonic probes).
4. Ibyiza byo gufata amashusho ya fotoacoustique: Itandukaniro ryinshi: Kwerekana amashusho bifata imiterere yibiranga urumuri rwimitsi, kandi inyama zitandukanye (nkamaraso, ibinure, imitsi, nibindi) zifite ubushobozi butandukanye bwo gukurura urumuri, kuburyo rushobora gutanga amashusho atandukanye cyane. Icyemezo gihanitse: Ukoresheje imiterere ihanitse ya ultrasound, amashusho yerekana amafoto arashobora kugera kuri milimetero cyangwa se munsi ya milimetero yerekana amashusho. Kudatera: Kwerekana amashusho ya fotoacoustic ntabwo ari igitero, urumuri nijwi ntabwo bizatera kwangirika kwinyama, bikwiriye cyane kwisuzumisha kwa muganga. Ubushobozi bwo gufata amashusho yimbitse: Ugereranije nu mashusho gakondo ya optique, amashusho yifoto arashobora kwinjira muri santimetero nyinshi munsi yuruhu, bikwiranye no gufata amashusho yimbitse.

2. Kumenya ibibyimba: - Angiogenezi mumyanya yibibyimba mubisanzwe iba myinshi cyane, kandi amashusho ya fotoacoustic arashobora gufasha gutahura hakiri kare ibibyimba mugutahura ibintu bidasanzwe mumiterere yimitsi.
3. Kwerekana amashusho akora: - Ifoto yerekana amafoto irashobora gusuzuma ogisijeni itanga ingirabuzimafatizo mu kumenya urugero rwa ogisijeni na deoxyhemoglobine mu ngingo, bifite akamaro kanini mu gukurikirana imikorere y’indwara nka kanseri n'indwara z'umutima.

Inzitizi nicyerekezo cyiterambere cyerekana amashusho:
Inkomoko yumucyogutoranya: Umucyo winjira muburebure butandukanye buratandukanye, uburyo bwo guhitamo neza uburebure bwumurambararo hamwe nuburebure bwimbitse ni ikibazo. Gutunganya ibimenyetso: Kubona no gutunganya ibimenyetso bya ultrasonic bisaba algorithm yihuta kandi yukuri, kandi iterambere ryikoranabuhanga ryubaka amashusho naryo ni ngombwa. Kwerekana amashusho menshi: Kwerekana amashusho birashobora guhuzwa nubundi buryo bwo gufata amashusho (nka MRI, CT, ultrasound imaging) kugirango utange amakuru yuzuye yibinyabuzima.

Amashusho ya Photoacoustic nubuhanga bushya kandi bukora byinshi muburyo bwa tekinoroji ya biomedical imaging, ifite ibiranga itandukaniro ryinshi, imiterere ihanitse kandi idatera. Hamwe niterambere ryikoranabuhanga, amashusho yerekana amafoto afite amahirwe menshi yo gukoreshwa mugupima ubuvuzi, ubushakashatsi bwibanze bwibinyabuzima, guteza imbere ibiyobyabwenge nizindi nzego.
