    	Ziel: Die Diagnose zerebrovaskulärer Erkrankungen stützt sich zunehmend
    	auf den Einsatz ultraschallbasierter Verfahren. Das kontrastmittelgestützte,
    	transkranielle Bolus Harmonic Imaging (BHI) hat hierbei einen hohen
    	Stellenwert. Die Auswertung der aufgezeichneten Bildsequenz erfolgt
    	durch geübte Ärzte jedoch manuell und ist somit zeitaufwendig. Das
    	Ziel der hier beschriebenen drei Verfahren ist die sichere, vollautomatische
    	Erkennung von Perfusionsdefekten des Gehirns. Material und Methoden:
    	Mit dem BHI werden Ultraschallbildsequenzen aufgezeichnet, die die
    	Kontrastmitteldynamik im Gehirn wiedergeben. Diese Bilder werden
    	mit drei verschiedenen Verfahren automatisch ausgewertet. Zum einen
    	wird ein regelbasiertes System beschrieben, welches aus den aufgezeichneten
    	Ultraschallbildern Parameterbilder extrahiert und diese mithilfe
    	von Expertenwissen nach perfundierten und minderperfundierten Gehirnarealen
    	klassifiziert. Zum zweiten erfolgt die Klassifikation der Gehirngebiete
    	unüberwacht mit dem K-Means-Verfahren. Hierzu wird jedes der Parameterbilder
    	als eine Dimension des zu klassifizierenden Merkmalsraums betrachtet,
    	sodass eine unüberwachte Segmentierung der minderperfundierten Gehirnbereiche
    	möglich ist. Drittens wird die gesamte Bildsequenz anhand der Kontrastmitteldynamik
    	pixelweise klassifiziert. Hierbei kann darauf verzichtet werden,
    	Parameterbilder extrahieren zu müssen. In allen drei Fällen ist es
    	im Anschluss notwendig, die beim HI auftretenden Streifenartefakte
    	automatisch zu erkennen. Abschließend wird ein Aussagenbild generiert,
    	in dem die gefundenen Minderperfusionen markiert sind. Ergebnisse:
    	Die drei Verfahren wurden auf einem 26 Patienten umfassenden Kollektiv
    	klinisch validiert. Hierbei hat sich herausgestellt, dass insbesondere
    	die Segmentierung anhand der Kontrastmitteldynamik dazu geeignet
    	ist, Minderperfusionen automatisch zu erkennen. Es konnte auf diesem
    	Patientenkollektiv eine Sensitivität von 100 % bei einer Spezifität
    	von 100 % erreicht werden. Schlussfolgerungen: Alle drei Verfahren
    	erscheinen geeignet, ischämische Gehirngebiete zu erkennen. Hierbei
    	liefert die Klassifikation von Gehirngebieten nach der Kontrastmitteldynamik
    	die besten Ergebnisse, da sie robust gegenüber Rauschen ist. Zudem
    	ist es das schnellste Verfahren, da die Extraktion von Parameterbildern
    	entfällt. Es ist notwendig, die Sensitivität und Spezifität auf einem
    	größeren Patientenkollektiv zu validieren. Eine sichere, vollautomatische
    	Erkennung von Perfusionsdefekten direkt am Patientenbett scheint
    	somit möglich zu sein.
    	
    	Abstract
    	
    	
    	Purpose: The diagnosis of ischemic stroke relies increasingly on the
    	usage of ultrasound-based methods. One of the recent methods is the
    	transcranial, contrast agent-based Bolus Harmonic Imaging (BHI) method.
    	The captured image sequence is manually examined by clinical experts
    	thus resulting in a time-consuming procedure. The purpose of this
    	study is to evaluate three different methods to analyze BHI image
    	sequences automatically for the detection of ischemic brain tissue.
    	Materials and Method: BHI captures an image sequence that provides
    	information on the dynamic behavior of the ultrasound contrast agents.
    	This image sequence is analyzed using three different procedures.
    	First a system relying on expert knowledge is used to determine perfusion
    	defects. This procedure requires parametric images, which are previously
    	extracted from the image sequence. The parameter images are then
    	categorized by an unsupervised classification method in well-perfused
    	and ischemic tissue by regarding the parametric images as features
    	describing the perfusion. Thirdly, the whole image sequence can be
    	interpreted as a pixel-by-pixel behavior out of contrast agents.
    	The dynamic curve of each pixel can be automatically classified as
    	perfused and ischemic tissue by the K-Means method without extracting
    	parametric images. In all three cases a closing step is necessary
    	for the accurate interpretation of the results. Transcranial ultrasound
    	imaging produces typical stripe artifacts that have to be detected
    	and eliminated. A result image is then created and provides a conclusion
    	about perfusion reduction in brain tissue. Results: All three methods
    	have been validated on the basis of 26 patients by clinical experts.
    	The segmentation on the contrast agent kinetics has proven to be
    	most effective. According to our patient database, it provides the
    	highest detection accuracy, resulting in a sensitivity of 100 % and
    	a specificity of 100 %. Conclusion: The presented methods seem to
    	be adequate for detecting ischemic brain tissue. The classification
    	of contrast agent kinetics provides the best results and has further
    	advantages. It is robust with respect to noise and the calculation
    	is fast because the extraction of parametric images is omitted. The
    	very high sensitivity and specificity must be validated in a larger
    	patient population. Reliable and automated detection of perfusion
    	defects at the bedside seems to be possible.},
