Hoton hoto (PAI) fasaha ce ta likitanci wacce ta haɗuna'urorin ganida acoustics don samar da siginar ultrasonic ta amfani da hulɗarhasketare da nama don samun manyan hotuna na nama. Ana amfani da shi sosai a fannonin ilimin halitta, musamman wajen gano ƙwayar cuta, hoton jijiyoyin jini, hoton fata da sauran fannoni.

Ka'ida:
1. Hasken haske da haɓakar zafi: - Hoton hoto yana amfani da tasirin thermal da aka samar da hasken haske. Kwayoyin launi da ke cikin nama (misali, haemoglobin, melanin) suna ɗaukar photons (yawanci kusa da hasken infrared), waɗanda suke canzawa zuwa makamashin zafi, yana haifar da yanayin zafi na gida.
2. Fadada zafin jiki yana haifar da duban dan tayi: - Haɓakar zafin jiki yana haifar da ƙaramin haɓakar zafin jiki na nama, wanda ke haifar da matsa lamba (watau duban dan tayi).
3. Ganewar Ultrasonic: - Raƙuman ruwa na ultrasonic da aka haifar suna yaduwa a cikin nama, kuma waɗannan sigina na gaba sun karɓa kuma ana yin rikodin su ta hanyar firikwensin ultrasonic (kamar binciken ultrasonic).
4. Sake gina hoto: Ana ƙididdige siginar ultrasonic da aka tattara kuma ana sarrafa shi don sake gina tsarin da hoton aikin nama, wanda zai iya samar da halayen halayen gani na nama. Amfanin hotunan hoto: Babban bambanci: Hoton hoto yana dogara ne akan halayen halayen haske na kyallen takarda, da nau'i daban-daban (kamar jini, mai, tsoka, da dai sauransu) suna da damar daban-daban don ɗaukar haske, don haka zai iya samar da hotuna masu mahimmanci. Babban ƙuduri: Yin amfani da babban ƙudurin sararin samaniya na duban dan tayi, hoton hoto yana iya cimma daidaiton hoto na milimita ko ma madaidaicin hoton millimita. Ba mai lalacewa ba: Hoton hoto na hoto ba shi da haɗari, haske da sauti ba zai haifar da lalacewar nama ba, wanda ya dace da ganewar asibiti na mutum. Ƙarfin hoto mai zurfi: Idan aka kwatanta da na'urar gani na gargajiya, hoton hoto na iya shiga santimita da yawa a ƙarƙashin fata, wanda ya dace da hoton nama mai zurfi.

Aikace-aikace:
1. Hoto na jijiyoyi: - Hoto na hoto na iya gano abubuwan da ke haifar da haske na haemoglobin a cikin jini, don haka zai iya nuna daidai da tsarin da yanayin oxygenation na jini don kula da microcirculation da yin hukunci akan cututtuka.
2. Ganewar Tumor: - Angiogenesis a cikin ƙwayoyin tumor yawanci suna da yawa sosai, kuma hotunan hoto na iya taimakawa farkon gano ciwace-ciwacen daji ta hanyar gano abubuwan da ba su da kyau a cikin tsarin jijiyoyin jini.
3. Hoto na aiki: - Hoton hoto na hoto zai iya tantance samar da iskar oxygen na kyallen takarda ta hanyar gano yawan iskar oxygenation da deoxyhemoglobin a cikin kyallen takarda, wanda ke da mahimmanci ga aikin kulawa da cututtuka irin su ciwon daji da cututtukan zuciya.
4. Hoto na fata: - Saboda hoton hoto yana da matukar damuwa ga nama na sama, ya dace da gano ciwon daji na fata da wuri da kuma nazarin matsalolin fata.
5. Hoto na kwakwalwa: Hoto na hoto na iya samun bayanan kwararar jini na cerebral ta hanyar da ba ta da tasiri don nazarin cututtukan kwakwalwa irin su bugun jini da farfadiya.

Kalubale da hanyoyin ci gaba na hoton hoto:
Madogarar haskeZaɓin: Shigar da haske na nau'ikan raƙuman ruwa daban-daban ya bambanta, yadda za a zaɓi madaidaicin ma'auni na tsayin raƙuman ruwa da zurfin shigar cikin ƙalubale. Yin siginar sigina: Samun da sarrafa siginar ultrasonic na buƙatar babban sauri da ingantaccen algorithms, kuma haɓaka fasahar sake gina hoto shima yana da mahimmanci. Multimodal Hoto: Za a iya haɗa hoton hoto tare da wasu hanyoyin yin hoto (irin su MRI, CT, duban dan tayi) don samar da ƙarin cikakkun bayanai na ilimin halitta.

Hoton hoto na hoto sabon fasaha ne mai aiki da yawa da ke aiki, wanda ke da halaye na babban bambanci, babban ƙuduri da mara amfani. Tare da haɓakar fasaha, hoton hoto yana da fa'idodin aikace-aikacen a cikin ganewar asali na likita, binciken ilimin halitta na asali, haɓaka magunguna da sauran fannoni.
