Hoton Hoto (PAI) wata dabara ce ta hoton likita da ke haɗuwana ganida kuma acoustics don samar da siginar ultrasonic ta amfani da hulɗarhasketare da nama don samun hotunan nama masu inganci. Ana amfani da shi sosai a fannoni na likitanci, musamman a gano ƙari, hoton jijiyoyin jini, hoton fata da sauran fannoni.

Ka'ida:
1. Shakar haske da faɗaɗa zafi: – Hoton daukar hoto yana amfani da tasirin zafi da shakar haske ke samarwa. Kwayoyin launin da ke cikin kyallen (misali, haemoglobin, melanin) suna shakar photons (yawanci hasken kusa da infrared), waɗanda ake mayar da su zuwa makamashin zafi, wanda ke haifar da hauhawar yanayin zafi na gida.
2. Faɗaɗawar zafi yana haifar da duban dan tayi: – Ƙarawar zafin jiki yana haifar da ƙaramin faɗaɗawar zafi na kyallen, wanda ke haifar da raƙuman matsin lamba (watau duban dan tayi).
3. Gano Ultrasonic: – Raƙuman ultrasonic da aka samar suna yaɗuwa a cikin kyallen, kuma daga baya ana karɓar waɗannan siginar ta hanyar na'urori masu auna sigina na ultrasonic (kamar na'urorin auna sigina na ultrasonic).
4. Sake gina hoto: ana ƙididdige siginar ultrasonic da aka tattara kuma ana sarrafa ta don sake gina siffa da aikin kyallen, wanda zai iya samar da halayen sha na gani na kyallen. Fa'idodin ɗaukar hoto na gani: Babban bambanci: Hoton hoto ya dogara ne akan halayen sha na haske na kyallen, kuma kyallen takarda daban-daban (kamar jini, kitse, tsoka, da sauransu) suna da iyawa daban-daban don shan haske, don haka yana iya samar da hotuna masu bambanci. Babban ƙuduri: Ta amfani da babban ƙudurin sararin samaniya na duban dan tayi, ɗaukar hoto na iya cimma daidaiton ɗaukar hoto na milimita ko ma ƙaramin milimita. Ba mai haɗari ba: Hoton hoto ba shi da haɗari, haske da sauti ba zai haifar da lalacewar kyallen ba, ya dace sosai don ganewar lafiyar ɗan adam. Ƙarfin ɗaukar hoto mai zurfi: Idan aka kwatanta da hoton gani na gargajiya, ɗaukar hoto na gani na iya ratsa santimita da yawa a ƙarƙashin fata, wanda ya dace da ɗaukar hoto mai zurfi na kyallen.

Aikace-aikace:
1. Hoton jijiyoyin jini: – Hoton daukar hoto na iya gano halayen da ke shanye haske na haemoglobin a cikin jini, don haka zai iya nuna daidai tsarin da yanayin iskar oxygen na tasoshin jini don sa ido kan ƙwayoyin cuta da kuma yin hukunci kan cututtuka.
2. Gano ƙari: – Angiogenesis a cikin kyallen ƙari yawanci yana da yawa sosai, kuma hoton daukar hoto na iya taimakawa wajen gano ƙari da wuri ta hanyar gano matsaloli a cikin tsarin jijiyoyin jini.
3. Hoton aiki: – Hoton daukar hoto zai iya tantance yawan iskar oxygen da kyallen ke samarwa ta hanyar gano yawan iskar oxygen da deoxyhemoglobin a cikin kyallen, wanda hakan yana da matukar muhimmanci ga sa ido kan cututtuka kamar ciwon daji da cututtukan zuciya da jijiyoyin jini.
4. Hoton fata: – Saboda hoton photoacoustic yana da matuƙar tasiri ga kyallen fata, ya dace da gano cutar kansar fata da wuri da kuma nazarin matsalolin fata.
5. Hoton kwakwalwa: Hoton daukar hoto na iya samun bayanai game da kwararar jinin kwakwalwa ta hanyar da ba ta da illa ga kwakwalwa don nazarin cututtukan kwakwalwa kamar bugun jini da farfadiya.

Kalubale da hanyoyin ci gaba na daukar hoton hoto:
Tushen haskeZaɓi: Shigar haske na tsawon tsayi daban-daban ya bambanta, yadda ake zaɓar madaidaicin ƙudurin ma'aunin tsayi da zurfin shigar ciki ƙalubale ne. Sarrafa sigina: Samo da sarrafa siginar ultrasonic suna buƙatar algorithms masu sauri da daidaito, kuma haɓaka fasahar sake gina hoto shima yana da mahimmanci. Hoton Multimodal: Ana iya haɗa hoton photoacoustic tare da wasu hanyoyin daukar hoto (kamar MRI, CT, hoton ultrasound) don samar da cikakkun bayanai game da ilimin halittu.

Hoton daukar hoto sabuwar fasaha ce mai amfani da fasahar daukar hoto mai aiki da yawa, wacce ke da halaye na babban bambanci, babban ƙuduri da kuma rashin cin zarafi. Tare da ci gaban fasaha, hoton daukar hoto yana da fa'idodi masu yawa na amfani a fannin ganewar asali na likita, binciken ilmin halitta na asali, haɓaka magunguna da sauran fannoni.
