Es produeix quan un vas sanguini cerebral esclata (o trenca) o es bloqueja per un coàgul. Els pacients amb ictus representen una emergència mèdica greu, i per tal d'augmentar la probabilitat de recuperació i reduir els danys del pacient, el risc de mort o les discapacitats futures, el diagnòstic i el tractament apropiats ipuntuals són crucials.  \nL'objectiu principal d'aquesta tesi és investigar l'ús de tècniques de Machine Learning (ML) per detectar i classificar ictus. El sistema utilitza “phantoms” jaque tenen les mateixes característiques elèctriques que els teixits del cap humà a freqüències de microones. Aquest projecte explora maneres de millorar la precisió i l'eficàcia de la detecció i classificació de ictus mitjançant l'aplicació de les capacitats computacionals del ML , amb l'objectiu de reduir elsefectes severs d'aquesta emergència mèdica.  \nPer últim , aquest estudi representa un desenvolupament interessant en laincorporació del ML en el diagnòstic de ictus cerebrals, amb el potencial de millorar la precisió i la velocitat del diagnòstic. Es pot desenvolupar encara més investigant estratègies alternatives com millorar els mètodes de classificació, provar diferents algorismes i calibrar simulacions amb mesuraments.  \nCom a activitat de recerca en curs, aquest projecte continua per millorar el diagnòstic i la predicció de ictus , motivat per la reducció dels efectes dels ictus, que canvien la vida als pacients.  \nTitle: Machine Learning techniques for microwave brain stroke detection and classification  \nAuthor: Emma Rodríguez Punset  \nDirector: Francesca Vipiana / Ernesto Serrano Finetti  \nDate: 24th October 2023  \nAbstract  \nStrokes, defined by an interruption of the supply of oxygenated blood to the brain, are devastating brain injuries that can cause profound damage, temporary or permanent disability, or even death. It occurs when a brain bloodvessel bursts (or ruptures) or becomes blocked by a clot. Stroke patients represent a serious medical emergency, and in order to increase the probability of recovery and lower the patient's damages, risk of death, or future disabilities, appropriate and timely diagnosis and treatment are crucial.  \nThe main objective of this thesis is to investigate the use of machine learning (ML) techniques to detect and classify strokes. The system used is placed according to head phantoms, which have the same electrical characteristics as human head tissues at microwave frequencies. This project explores ways to improve the precision and efficacy of stroke detection and classification by applying machine learning's computational capabilities, ultimately with the goal of reducing the severe effects of this medical emergency.  \nUltimately, this study represents an interesting development in the incorporation of machine learning into stroke diagnosis, with the potential to improve the accuracy and speed of diagnosis. It can be further developed by investigating alternative strategies such as improving classification methods, testing different algorithms, and calibrating simulations with measurements. As an ongoing research activity, the continuing journey to improve stroke diagnosis and prediction will continue, motivated by reducing the life-changing eff","cbCairkD1Lf0dCaG","https://ap.wps.com/l/cbCairkD1Lf0dCaG","pdf",2396291,1,119,"English","en",105,"# INTRODUCTION\n# CHAPTER 1.
