Abstract
Description
Die Erfindung bezieht sich auf eine Einrichtung zum Erzeugen von Ultraschallstrahlen für die Ultraschalltherapie.The invention relates to a Device for generating ultrasound beams for ultrasound therapy.
Beim therapeutischen Einsatz von Ultraschallstrahlen mit hoher Intensität, beispielsweise bei der Lithotripsie oder bei der Hyperthermie ist es erforderlich, die Tiefenlage des Fokus im Körper verändern zu können. Darüber hinaus besteht auch ein Bedarf, die Form des Fokus den jeweiligen Einsatzbedingungen – Größe des Konkrements oder des nekrotischen Gewächses – anzupassen, ohne dass es hierzu einer Änderung der Position der Ultraschallquelle relativ zum Körper oder eines mechanischen Austausches von abbildenden Komponenten bedarf.With the therapeutic use of High-intensity ultrasound beams, for example in lithotripsy or with hyperthermia it is necessary to determine the depth of the Focus in the body change to be able to. About that there is also a need to shape the focus of each Conditions of use - size of the calculus or the necrotic crop - to adapt, without making any change to this the position of the ultrasound source relative to the body or a mechanical exchange of imaging components.

Die beiden letztgenannten Einrichtungen haben den Nachteil, dass zur Veränderung des Fokus eine mechanische Veränderung der Abbildungsgeometrie erforderlich ist.The latter two institutions have the disadvantage of changing the focus is a mechanical change the imaging geometry is required.
Alternativ hierzu ist aus J.Y. Chapelon et al., „The Feasibility of Tissue Ablation using High Intensity Electronically Focused Ultrasound", Proceedings IEEE Ultrasonic Symposium, Seiten 1211–1214, ein ringförmiges Array bekannt, dessen einzelne Wandlerelemente phasenverzögert angesteuert werden können, so dass die Tiefenlage des Fokus elektronisch einstellbar ist. Die Ansteuerung eines solchen Phased Array ist jedoch technisch aufwendig.Alternatively, J.Y. Chapelon et al., "The Feasibility of Tissue Ablation using High Intensity Electronically Focused Ultrasound ", Proceedings IEEE Ultrasonic Symposium, pages 1211–1214, a ring-shaped array known, whose individual converter elements are driven with a phase delay can be so that the depth of focus can be adjusted electronically. The Controlling such a phased array is technically complex.
Der Erfindung liegt nun die Aufgabe zu Grunde, eine Einrichtung zum Erzeugen von Ultraschallstrahlen für die Ultraschalltherapie anzugeben, die auf einfache Weise eine Verän derung der Fokuslage oder der Fokusform bei zugleich hoher Fokusqualität ermöglicht.The object of the invention is now based, a device for generating ultrasound beams for the To indicate ultrasound therapy, which is a simple change the focus position or the focus shape with high focus quality.
Die genannte Aufgabe wird gelöst mit einer Einrichtung mit den Merkmalen des Patentanspruches 1. Gemäß diesen Merkmalen enthält eine Einrichtung zum Erzeugen von Ultraschallstrahlen für die Ultraschalltherapie eine Mehrzahl von getrennt voneinander ansteuerbaren Ultraschallsendern, die Ultraschallstrahlen erzeugen, deren jeweilige Foki voneinander verschieden sind, d. h. sich an unterschiedlichen Orten befinden und/oder unterschiedlichen Durchmesser aufweisen. Jeder Ultraschallsender umfasst eine Ultraschallquelle, der zum Fokussieren der von ihr erzeugten Ultraschallstrahlen eine nahe an der Abstrahlfläche der Ultraschallquelle angeordnete Linse zugeordnet ist. Mit jedem Ultraschallsender können somit auch dann, wenn er allein angesteuert wird, zur Ultraschalltherapie geeignete fokussierte Ultraschallstrahlen mit hoher Fokusqualität erzeugt werden, da die Linsen nahe an den Abstrahlflächen der Ultraschallquellen angeordnet sind. Die Auswahl des jeweils verwendeten Ultraschallsenders hängt nur von den in der konkreten therapeutischen Situation gegebenen Anforderungen an die Eigenschaften des Fokus, d. h. in erster Linie seine Tiefenlage und Fokusausdehnung, ab. Da eine Mehrzahl von Ultraschallsendern mit voneinander verschiedenen Foki vorgesehen ist, können mit ein und derselben Einrichtung ohne die Notwendigkeit von zeitaufwendigen Umbaumaßnahmen unterschiedliche therapeutische Anforderungen erfüllt werden. Da außerdem jeder Ultraschallsender für sich einen therapeutisch nutzbaren fokussierten Ultraschallstrahl erzeugt, entfällt die Notwendigkeit einer aufwendigen phasenverzögerten Ansteuerung einer Vielzahl von Ultraschallsendern. Desweiteren können durch die Verwendung von Linsen zur Abbildung Ultraschallquellen verwendet werden, die eine ebene Abstrahlfläche und somit einen konstruktiv einfachen Aufbau aufweisen.The stated object is achieved with a device having the features of patent claim 1. According to these features, a device for generating ultrasound beams for ultrasound therapy contains a plurality of ultrasound transmitters which can be controlled separately from one another and which generate ultrasound beams, the respective foci of which are different from one another, that is, per se are located in different locations and / or have different diameters. Each ultrasound transmitter comprises an ultrasound source, which is assigned a lens arranged close to the radiation surface of the ultrasound source in order to focus the ultrasound beams it generates. With each ultrasound transmitter, even when it is controlled alone, suitable ultrasound beams with high focus quality suitable for ultrasound therapy can be generated, since the lenses are arranged close to the radiation surfaces of the ultrasound sources. The selection of the ultrasound transmitter used in each case depends only on the requirements for the properties of the focus, ie primarily its depth and focus extension, given in the specific therapeutic situation. Since a plurality of ultrasound transmitters with different foci are provided, different therapeutic requirements can be met with one and the same device without the need for time-consuming conversion measures. In addition, since each ultrasound transmitter generates a therapeutically usable focused ultrasound beam, there is no need for complex phase-delayed control of a large number of ultrasound transmitters. Furthermore, by using lenses for imaging, ultrasound sources can be used, which is a flat radiation surface and thus have a structurally simple structure.
Insbesondere in Verbindung mit Ultraschallquellen mit planen Abstrahlflächen ist die Verwendung von plankonkaven Linsen von Vorteil, deren Planfläche jeweils der ihr zugeordneten Ultraschallquelle zugewandt ist. Dies ermöglicht einen kompakten Aufbau der Einrichtung, da die Linsen unmittelbar, d. h. flächenbündig an die Abstrahlfläche angekoppelt werden können.Especially in connection with ultrasound sources with flat radiation surfaces the use of plano-concave lenses is advantageous, the flat surface of each is facing the ultrasound source assigned to it. This enables one compact structure of the device, since the lenses immediately, i. H. flush to the surface the radiation area can be coupled.
In einer weiteren vorteilhaften Ausführungsform sind die zu verschiedenen Ultraschallsendern gehörenden Linsen aus unterschiedlichen Werkstoffen aufgebaut.In a further advantageous embodiment are the lenses belonging to different ultrasound transmitters from different Materials built up.
Ein besonders kompakter Aufbau lässt sich dann verwirklichen, wenn die Ultraschallsender eine um eine gemeinsame Mittenachse rotationssymmetrische Sendefläche aufweisen, und jeweils einen Fokus erzeugen, der auf dieser gemeinsamen Mittenachse liegt.A particularly compact construction can then be made realize when the ultrasound transmitters are one to a common Center axis have rotationally symmetrical transmission surface, and each generate a focus that lies on this common central axis.
Die genannte Aufgabe wird außerdem mit einer Einrichtung mit den Merkmalen des Patentanspruches 5 gelöst. Anstelle der Verwendung von Linsen zum Erzeugen von fokussierten Stoßwellen ist gemäß Patentanspruch 5 die Verwendung von Ultraschallquellen vorgesehen, die von vornherein eine gekrümmte Abstrahlfläche derart aufweisen, dass die von ihnen emittierten Ultraschallwellen fokussiert sind.The task mentioned is also with a device with the features of claim 5 solved. Instead of the use of lenses to generate focused shock waves is according to claim 5 provided the use of ultrasound sources from the outset a curved one radiating have such that the ultrasonic waves emitted by them are focused.
Zur weiteren Erläuterung der Erfindung wird auf die Ausführungsbeispiele der Zeichnung verwiesen. Es zeigen:To further explain the invention, reference is made to the embodiments referred to the drawing. Show it:
Gemäß
Die Ultraschallsender S1 bis S3 sind einzeln ansteuerbar, so dass sich je nach Auswahl des angesteuerten Ultraschallsenders (in der Figur S1) eine unterschiedliche Tiefenlage des Fokus (in der Figur Ultraschallstrahl U1 mit Fokus F1) ergibt. Werden mehrere Ultraschallsender S1 bis S3 gleichzeitig angesteuert, so ergibt sich je nach Auswahl der Ultraschallsender S1 bis S3 eine Veränderung der räumlichen Lage und Ausdehnung des Fokusgebietes.The ultrasonic transmitters are S1 to S3 individually controllable, so that depending on the selection of the controlled Ultrasonic transmitter (in the figure S1) a different depth of the focus (ultrasound beam U1 with focus F1 in the figure). If several ultrasonic transmitters S1 to S3 are activated at the same time, depending on the selection of the ultrasonic transmitters S1 to S3, one results change the spatial Location and extent of the focus area.

Die Erfindung ist außerdem nicht auf konzentrische, ringförmige Anordnungen der Ultraschallsender beschränkt. Vielmehr ist es ausreichend, wenn die Einrichtung eine Mehrzahl von Ultraschallsendern enthält, die getrennt voneinander angesteuert werden können, und die Ultraschallstrahlen erzeugen, deren jeweilige Foki unterschiedliche Eigenschaften (Fokuslage, Fokuslänge oder Fokusdurchmesser) aufweisen.The invention is also not limited to concentric, ring-shaped arrangements of the ultrasonic transmitters. Rather, it is sufficient if the device has a plurality of ultrasound scanners Contains, which can be controlled separately, and generate the ultrasound beams, the respective foci have different properties (focus position, focus length or focus diameter).
