Abstract
Description
Die Erfindung betrifft Verfahren und eine Vorrichtung Verfahren zur Bilddarstellung eines interessierenden Untersuchungsbereichs im Rahmen einer medizinischen Untersuchung oder Behandlung.The The invention relates to methods and a device method for Image representation of an investigation area of interest in Frame of a medical examination or treatment.
Die Erfindung wird beispielsweise bei der intra-operativen Bildgebung während einer medizinischen Intervention angewendet. Während einer medizinischen Intervention werden zur Navigation von medizinischen Instrumenten Echtzeitbilder (Live-Bilder) z. B. mit Hilfe von fluoroskopischer Durchleuchtung gewonnen. Verglichen mit 3-D-Angiographie-Bildern zeigen diese Durchleuchtungs- oder 2-D-Akquisitions-Bilder zwar keine räumlichen (3-D) Details, sie sind jedoch schneller verfügbar und minimieren die Strahlenbelastung für Patient und Arzt. Idealerweise wird nun die räumliche Information dadurch zurückgewonnen, dass prä- oder intra-operativ erzeugte 3-D-Bilder z. B. von CT-, 3-D-Angio-, C-Arm-CT- oder MR-Aufnahmen mit den zweidimensionalen Bildern registriert werden. Die Kombination von co-registrierten oder fusionierten 2-D- und 3-D-Bildern erlaubt dem Arzt nun eine bessere Orientierung im Volumen. Diese 2-D/3-D-Registrierung besteht aus zwei Schritten.The Invention is used, for example, in intra-operative imaging while applied to a medical intervention. During a medical intervention Real-time images are used to navigate medical instruments (Live pictures) z. B. obtained by means of fluoroscopic fluoroscopy. Compared with 3-D angiography images show these transillumination or 2-D acquisition images although no spatial (3-D) details, but they are faster available and minimize radiation exposure for patient and doctor. Ideally, the spatial information is now recovered that or intraoperatively generated 3-D images z. From CT, 3-D angio, C-arm CT or MR images with the two-dimensional ones Pictures are registered. The combination of co-registered or fused 2-D and 3-D images now allows the doctor one better orientation in volume. This 2-D / 3-D registration exists in two steps.
1. Bildregistrierung:1st picture registration:
Zunächst muss bestimmt werden, aus welcher Richtung ein 3-D-Volumen projiziert werden muss, damit es mit dem 2-D-Bild in Deckung gebracht werden kann. Hierfür gibt es verschiedene Ansätze, die beispielsweise in Penney [1] beschrieben sind.First of all must determine from which direction a 3-D volume must be projected so that it can be brought into line with the 2-D image. There are for this different approaches, which are described for example in Penney [1].
2. Visualisierung:2. Visualization:
Das zweite Problem ist die Visualisierung der registrierten Bilder, d. h. die gemeinsame Darstellung von 2-D-Bild und projiziertem 3-D-Bild. Die Standardmethode hierfür ist die sogenannte Überlagerung, auch ”Overlay” genannt, bei dem die beiden Bilder anhand verschiedener Methoden übereinander gelegt werden, wie dies beispielsweise schon in der älteren Patentanmeldung [2] vorgeschlagen worden ist.The second problem is the visualization of the registered images, d. H. the joint representation of 2-D image and projected 3-D image. The standard method for this is the so-called overlay, also called "overlay", in which the two images on each other using different methods be laid, as for example, already in the earlier patent application [2] has been proposed.
Durch die Überlagerung zweier Röntgenbilder können Unterschiede dargestellt werden. Solche Unterschiede können Transformationen sein, d. h. die beiden Röntgenbilder sind gegeneinander verschoben und/oder rotiert (das bei einer Patientenbewegung häufig geschehen kann). Die aus der Patientenbewegung resultierende Transformation (Verschiebung und/oder Rotation) zwischen den beiden Bildern sollte in der Überlagerung erkennbar sein. Dann ist es möglich die Orientierung des 3D-Datensatzes so zu verändern, dass die Patientenbewegung kompensiert wird und keine Unterschiede mehr in der Überlagerung zu erkennen sind. Anschließend sind der 3D-Datensatz und das Live-2D-Röntgenbild wieder korrekt registriert.By the overlay two x-rays can Differences are presented. Such differences can transformations be, d. H. the two x-rays are shifted against each other and / or rotated (that in a patient movement often can happen). The transformation resulting from the patient movement (Shift and / or rotation) should be between the two pictures in the overlay be recognizable. Then it is possible to change the orientation of the 3D dataset so that the patient movement is compensated and no longer in the overlay can be seen. Then are the 3D data set and the live 2D X-ray image correctly registered again.
Um auch anatomische Veränderungen, wie z. B. Embolisation von zugeführenden Gefäßen bei einer Tumorbehandlung, eingebrachte Coils oder Stents bei einer Aneurysma- bzw. Stenosebehandlung zu erkennen, sind post-interventionelle 3D-Hochkontrastkontrollaufnahmen erforderlich. Ein Vergleich (vorher/nachher) ist zum Beispiel mit einer Funktion möglich, welche zwei 3D-Hochkontrstaaufnahmen zusammengefügt, so dass beide Hochkontrastaufnahmen gleichzeitig angezeigt werden können. Mit einer derartigen Funktion ist es beispielsweise möglich, sowohl die prä-interventionelle Hochkontrastaufnahme einer Stenose, als auch die post-interventionelle Hochkontrastaufnahme dieser Stenose inklusive der eingebrachten Coils in einem 3D Bild dazustellen.Around also anatomical changes, such as B. embolization of supplying Vessels at one Tumor treatment, inserted coils or stents in an aneurysm or stenosis treatment are post-interventional 3D-Hochkontrastkontrollaufnahmen required. A comparison (before / after) is for example with a function possible, which combines two 3D high-contrast images, so that both high-contrast images can be displayed at the same time. With such a function, it is possible, for example, both the pre-interventional High contrast image of a stenosis, as well as the post-interventional High-contrast image of this stenosis including the introduced To present coils in a 3D image.
Solche post-interventionellen 3D-Aufnahmen sind dahingehend ungünstig, dass sie eine zusätzliche Dosis- /Kontrastmittelapplikation erfordern, die interventionelle Prozedur in die Länge (erneute 3D-Rekonstruktion) ziehen und den Patienten z. B. durch Atemkontrolle unnötig belasten.Such Post-interventional 3D images are unfavorable in that she an extra Dose / contrast application require lengthening the interventional procedure (re-3D reconstruction) pull and the patient z. B. unnecessarily burden by breathing control.
Es ist nun Aufgabe der Erfindung, ein Verfahren bzw. eine Vorrichtung so auszugestalten, dass die Bilddarstellung von Unterschieden bzw. Abweichungen während einer medizinischen Intervention verbessert und gleichzeitig die Strahlendosis bzw. Kontrastmittelanwendungen verringert wird.It Now is an object of the invention, a method and a device in such a way that the image representation of differences or Deviations during a medical intervention improves while the Radiation dose or contrast agent applications is reduced.
Diese Aufgabe wird durch die in den unabhängigen Patentansprüchen angegebenenen Merkmale gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den abhängigen Patentansprüchen angegeben.These The object is achieved by the specified in the independent claims Characteristics solved. Advantageous developments of the invention are specified in the dependent claims.
Gegenstand der Erfindung ist ein Verfahren zur Bilddarstellung eines interessierenden Untersuchungsbereichs im Rahmen einer medizinischen Untersuchung oder Behandlung. Das erfindungsgemäße Verfahren weist dabei folgende Schritte auf:

- b) Verwenden wenigstens eines intraoperativ aufgenommenen 2D-Durchleuchtungsbilds bzw. Akquisitionsbilds des Untersuchungsbereichs
- c) Registrieren des 3D-Rekonstruktionsbilds bezüglich des 2D-Durchleuchtungsbilds, – Überlagern des 2D-Durchleuchtungsbilds bzw. Akquisitionsbilds über das 3D-Rekonstruktionsbild,
- d) Detektieren von Abweichungen in Strukturen des Untersuchungsbereichs bei der Überlagerung und Kennzeichnen derer in einer Darstellung des Rekonstruktionsbildes an einer Anzeigevorrichtung.
- a) using a preoperative 3D image data set of the examination area and generating a 3D reconstruction image of the examination area,
- b) using at least one intraoperatively recorded 2D fluoroscopic image or acquisition image of the examination region
- c) registering the 3D reconstruction image with respect to the 2D fluoroscopic image, overlaying the 2D fluoroscopic image or acquisition image via the 3D reconstruction image,
- d) Detecting deviations in structures of the examination area in the superimposition and marking of them in a representation of the reconstruction image on a display device.
Solche Strukturen können beispielsweise Gefäße, Knochen, Organe, Implantate (Stents, Coils) und evtl. Tumore etc. sein.Such Structures can for example, vessels, bones, Organs, implants (stents, coils) and possibly tumors etc.
Zweckmäßigerweise wird die Kennzeichnung der Abweichungen mit einer Farbe oder mit einem sich von den Strukturen unterscheidenden Grauwert dargestellt.Conveniently, is the marking of deviations with a color or with a gray value different from the structures.
In vorteilhafter Weise wird das 2D-Durchleuchtungsbild bzw. Akquisitionsbilds in die Darstellung des Rekonstruktonsbildes nach Schritt d) von Anspruch 1 überlagert eingeblendet, wobei das 2D-Durchleuchtungsbild in der Darstellung des Rekonstruktonsbildes nach Schritt d) auch ausblendbar ist.In Advantageously, the 2D fluoroscopic image or acquisition image in the representation of the reconstructed image after step d) of claim 1 superimposed with the 2D fluoroscopic image displayed of the reconstructed image after step d) can also be faded out.
Ein weiterer Aspekt der Erfindung ist eine bildgebende Vorrichtung, ausgebildet mit Mitteln zur Bilddarstellung eines interessierenden Untersuchungsbereichs im Rahmen einer medizinischen Untersuchung oder Behandlung gemäß den Schritten des vorstehend erläuterten Verfahrens.One Another aspect of the invention is an imaging device, formed with means for displaying a picture of interest Investigation area as part of a medical examination or treatment according to the steps of explained above Process.
Die
Erfindung weist folgende Vorteile auf:
Durch die erfindungsgemäß gegebenenfalls
farbig visualisierte Darstellung von Unterschieden bei der Überlagerung
von Röntgenbildern,
können
die Abweichungen bzw. Unterschiede den Ausgangsröntgenbildern leicht zugeordnet
werden.The invention has the following advantages:
The representation of differences in the superimposition of x-ray images, which may be visualized in color in accordance with the invention, may easily be attributed to the deviations or differences from the initial x-ray images.
Anstatt ursprünglich mehrerer 3D-Aufnahmen reicht nun eine initiale 3D-Aufnahme aus, welche regelmäßig an Veränderungen angepasst werden kann. Dadurch wird dem Patienten Strahlung, Kontrastmittel und das Ausführen von Atemkommandos erspart.Instead of originally several 3D shots, an initial 3D image is enough which regularly changes can be adjusted. This will give the patient radiation, contrast medium and the running saves breathing commands.
