Da zarar an gano fasalulluka, mataki na gaba shine a rarraba da kuma nazarin siginar da za a samu bayanan likita wanda yake da amfani. Sau da yawa ana amfani da koyon injina da zurfafa ilmantarwa a wannan matakin.
5. Fassara da Ganewar Cututtuka
Bayan haka, ana fassara sakamakon binciken don taimaka wa likita wajen yin ganewar asali da kuma tsara magani. Cikakken fassarar yana da matuƙar muhimmanci, domin zai tantance matakan lafiya na gaba.
Dabaru na Sarrafa Siginar Halittu
1. Fourier Transform
Ana amfani da Fourier transform don canza sigina a yankin lokaci zuwa yankin mita. Wannan dabarar tana da amfani wajen nazarin sassan mita na siginar biomedical, kamar mitar bugun zuciya ko aikin kwakwalwa.
2. Binciken Canjin Wavelet
Ana amfani da nazarin yanayin raƙuman ruwa mai sauri don fitar da bayanai na lokaci da mita a lokaci guda. Wannan dabarar ta dace musamman ga siginar likitanci marasa tsayawa, kamar EEG.
3. Matatar Dijital
Ana amfani da matatun dijital (kamar matatun ƙasa-ƙasa, masu wucewa ta sama, ko masu wucewa ta band) don cire hayaniya ko abubuwan da ba a so daga sigina.
4. Babban Binciken Sassan (PCA)
Ana amfani da PCA don rage girman bayanai masu rikitarwa zuwa manyan sassa da dama, don haka yana sauƙaƙa bincike.
5. Koyon Inji da Zurfin Koyo
Ana amfani da algorithms na koyon injina (kamar SVM, Decision Trees) da zurfin ilmantarwa (kamar CNN, RNN) don rarrabawa da nazarin siginar likitanci ta atomatik.
Aikace-aikacen Sarrafa Sigina a cikin Magungunan Halittu
1. Ganewar Cututtukan Zuciya da Jijiyoyin Jini
Ana amfani da siginar ECG don gano cututtukan zuciya daban-daban kamar su arrhythmias, ischemia, da bugun zuciya. Dabaru kamar Fourier transforms da na'ura learning suna taimakawa wajen gano alamu marasa kyau a cikin siginar ECG.
2. Kula da Barci da Ingancin Barci
Ana amfani da siginar EEG da EOG (electrooculogram) don sa ido kan zagayowar barci da kuma nazarin matsalolin barci kamar su apnea na barci. Dabaru na nazari Ana amfani da raƙuman ruwa masu sauri (wavelets) da kuma koyon injina don rarraba matakan barci.
3. Gyaran Jijiyoyin Jijiyoyi
Ana amfani da siginar EMG wajen gyaran jijiyoyin jijiyoyi don sa ido da kimanta ayyukan tsoka. Sau da yawa ana amfani da matattara ta dijital don cire hayaniya, yayin da ake amfani da PCA da koyon injin don bincika bayanai Bugu da kari.
4. Kulawa da Lafiyar Jiki Ba Tare da Mamayewa Ba
Ana amfani da siginar PPG don sa ido ba tare da yin kutse ba game da bugun zuciya, cikar iskar oxygen, da sauran sigogin ilimin halittar jiki. Ana amfani da matattara na dijital da koyon injin don tabbatar da daidaiton bayanan fitarwa.
5. Ganewar Cututtukan Kwakwalwa
Ana amfani da siginar EEG don gano cututtukan jijiyoyi kamar su farfadiya, schizophrenia, da ADHD. Ana amfani da dabaru kamar Fourier transforms, wavelets, da zurfin ilmantarwa don gano alamu marasa kyau a cikin aikin kwakwalwa.
Kalubale a Tsarin Sarrafa Siginar Halittu
1. Hayaniya da Kayan Tarihi
Hayaniya da kayan tarihi daga tushe na waje ko jikin kanta sau da yawa suna tsoma baki ga samun siginar biomedical. Wannan ƙalubalen yana buƙatar amfani da dabarun tacewa masu inganci da kuma algorithms na gano kayan tarihi.
2. Daidaito da Sauyawa
Bambancin da ke tsakanin mutane a cikin siginar likitanci yana sa ya yi wuya a samar da sakamako mai daidaito. Dole ne algorithms ɗin da aka yi amfani da su su iya daidaitawa da wannan bambancin.
3. Fassarar Bayanan Rikici
Dabaru da yawa na nazari suna samar da bayanai masu rikitarwa waɗanda ke da wahalar fassarawa ga ƙwararrun likitoci. Saboda haka, ana buƙatar tsarin da ba wai kawai yake daidai ba har ma yana da sauƙin amfani.
4. Aiki na hakika
Sau da yawa sarrafa siginar biomedical yana buƙatar sarrafawa a ainihin lokaci, wanda ke buƙatar sauri da inganci wajen samun sigina da kuma nazarin su.
Kammalawa
Tsarin sarrafa siginar biomedical fanni ne mai saurin canzawa, wanda ke ba da dabaru iri-iri waɗanda za a iya amfani da su don aikace-aikacen likita iri-iri. Daga binciken cututtukan zuciya da jijiyoyin jini zuwa gyaran jijiyoyin jini, sarrafa siginar biomedical yana taka muhimmiyar rawa wajen inganta matakan kiwon lafiya. Duk da ƙalubale da yawa, ci gaban fasaha da algorithms na nazari za su ci gaba da tura iyakokin abin da zai yiwu, wanda ke kusantar da mu kusa da ingantattun bincike da ingantattun jiyya na likita.
