Nheyo dzemifananidzo yeacoustic

Kufungidzira kwePhotoacoustic (PAI) inzira yekurapa inosanganisa mifananidzo yekurapaopticsuye maacoustics ekugadzira masaini e ultrasonic achishandisa kudyidzana kwechiedzanenyama kuti vawane mifananidzo yenyama yakajeka. Inoshandiswa zvakanyanya muminda yezvekurapa, kunyanya mukuona bundu, tsinga dzeropa, ganda nemamwe minda.

Nheyo:
1. Kupinza chiedza uye kuwedzera kupisa: – Kufungidzira kwemifananidzo kunoshandisa mhedzisiro yekupisa inokonzerwa nekupinza chiedza. Mamorekuru epigment ari munyama (semuenzaniso, hemoglobin, melanin) anopinza maphoton (kazhinji chiedza chepedyo neinfrared), ayo anoshandurwa kuita simba rekupisa, zvichiita kuti tembiricha yemunzvimbo ikwire.
2. Kuwedzera kwekupisa kunokonzera ultrasound: – Kukwira kwekupisa kunotungamira kukura kudiki kwekupisa kwenyama, izvo zvinoburitsa mafungu ekumanikidzwa (kureva ultrasound).
3. Kuonekwa kweUltrasonic: – Mafungu eUltrasonic anokonzerwa anopararira mukati menyama, uye zviratidzo izvi zvinozogamuchirwa uye zvinonyorwa nemasensa eUltrasonic (akadai semapurobe eUltrasonic).
4. Kugadziriswazve kwemufananidzo: chiratidzo che ultrasonic chakaunganidzwa chinoverengwa uye chinogadziriswa kuti chivakwezve chimiro uye mufananidzo wekushanda kwenyama, izvo zvinogona kupa hunhu hwe optical absorption yenyama. Mabhenefiti e photoacoustic imaging: High contrast: Photoacoustic imaging inoenderana nehunhu hwechiedza hwenyama, uye nyama dzakasiyana (dzakadai seropa, mafuta, tsandanyama, nezvimwewo) dzine hunyanzvi hwakasiyana hwekupinza chiedza, saka dzinogona kupa mifananidzo yakasiyana-siyana. High resolution: Uchishandisa high spatial resolution ye ultrasound, photoacoustic imaging inogona kuwana millimeter kana kunyange sub-millimeter imaging accuracy. Non-invasive: Photoacoustic imaging haina invasive, chiedza uye ruzha hazvizokonzere kukuvara kwenyama, zvakakodzera kuongororwa kwevanhu. Kugona kwemifananidzo yakadzika: Kana tichienzanisa ne optical imaging yechinyakare, photoacoustic imaging inogona kupinda masendimita akati wandei pasi peganda, iyo yakakodzera ku deep tissue imaging.

Kushandiswa:
1. Kufungidzira kwetsinga dzeropa: – Kufungidzira kwemifananidzo yeacoustic kunogona kuona hunhu hwehemoglobin inonwisa chiedza muropa, saka kunogona kuratidza nemazvo chimiro uye mamiriro emidziyo yeropa yekufema kwemweya kuti iongorore kufamba kweropa muropa uye kuongorora zvirwere.
2. Kuonekwa kwebundu: – Kuonekwa kwebundu munyama dzebundu kunowanzo kuve kwakawanda, uye mifananidzo ye photoacoustic inogona kubatsira kuona bundu nekukurumidza nekuona kusagadzikana muchimiro chetsinga dzeropa.
3. Kufungidzira mashandiro emuviri: – Kufungidzira kwemifananidzo kunogona kuongorora kugoverwa kweokisijeni mumatishu nekuona huwandu hweoxygenation uye deoxyhemoglobin mumatishu, izvo zvakakosha zvikuru pakutarisa mashandiro ezvirwere zvakaita sekenza nezvirwere zvemwoyo.
4. Kufungidzira ganda: – Nekuti mifananidzo ye photoacoustic inonyanya kubatwa nenyama yepamusoro, yakakodzera kuona kenza yeganda nekukurumidza uye kuongorora zvikanganiso zveganda.
5. Kufungidzira uropi: Kufungidzira uropi neacoustic kunogona kuwana ruzivo rwekuyerera kweropa muuropi nenzira isingakuvadzi vanhu kuti vadzidze zvirwere zveuropi zvakaita sestroke nepfari.

Matambudziko uye nzira dzekuvandudza mifananidzo yemifananidzo:
Chitubu chechiedzaKusarudzwa: Kupinda kwechiedza muma wavelength akasiyana kwakasiyana, nzira yekusarudza resolution chaiyo ye wavelength balance uye kudzika kwekupinda idambudziko. Kugadzirisa masaini: Kuwana nekugadzirisa masaini e ultrasonic kunoda ma algorithms ekumhanya uye akarurama, uye kuvandudzwa kwetekinoroji yekuvakazve mifananidzo kwakakoshawo. Kufungidzira kwe multimodal: Kufungidzira kwe photoacoustic kunogona kusanganiswa nedzimwe nzira dzekufungidzira (dzakadai se MRI, CT, ultrasound imaging) kuti ipe ruzivo rwakakwana rwe biomedical.

Kufungidzira mifananidzo yeacoustic tekinoroji itsva uye inoshanda zvakasiyana-siyana yekurapa, ine hunhu hwekuenzanisa kwakanyanya, kugona kupenya kwakanyanya uye kusapindira mumuviri. Nekuvandudzwa kwetekinoroji, kufungidzira mifananidzo yeacoustic kune mikana yakawanda yekushandiswa mukuongorora kwekurapa, kutsvagurudza kwebhayoloji, kugadzirwa kwemishonga nedzimwe nzvimbo.
