Definitions
- the invention relates to a method for the simultaneous, parallel, continuous display of stored, high-resolution diagnostic 3-D image data and 2-D real-time image data during a medical intervention of a patient and an arrangement for carrying out this method.
- DE 10 2006 003 126 A1 discloses a method and a device for visualizing three-dimensional objects, in particular in real time.
- a three-dimensional image data set of the object is created and registered with recorded two-dimensional fluoroscopic images of the object.
- the edges of the object are extracted from the three-dimensional data set and visually overlaid with the two-dimensional transillumination images with the edges of the object.
- the disadvantage of the visualization according to 10 2006 003 126 A1 is that after the 2 -D / 3 -D registration, an intuitive representation and coupling of the two image modalities must take place in a display window (manually with the aid of a joystick operated by the operator).
- DE 10 2007 051 479 A1 discloses a method and a device for displaying image data of several image data sets during a medical, in particular abdominal, intervention, which is based on the disclosure of DE 10 2006 003 126 A1.
- the method according to DE 10 2007 051 479 A1 comprises the following steps:
- Viewing angle or Advicehahme distance of the two-dimensional image data set can be set to the target area.
- a dual-monitor system is used for synchronous three-dimensional image display.
- DE 10 2005 023 167 A1 discloses a method and a device for registering 2-D projection images of an object relative to a 3-D image data set of the same object, in which only a few 2-D projection buffers a 3 : D feature contained in the object, which is also identifiable in the 3 -D images is symbolically reconstituted. The 3-D feature thus obtained is then registered by 3-D-3-D registration with the 3-D image data set.
- DE 103 59 317 A1 discloses a method for the targeted navigation of a medical instrument introduced invasively into a hollow organ of the human or animal body, in particular of a catheter, to a pathological location in the hollow organ, in which a first image representation recorded beforehand by means of a non-invasive examination modality at least a portion of the cavity organ determines the position of one or more pathological sites and the image representation is reproduced during the subsequent navigation of the instrument along with a continuous angiographically recorded angiographic image representation of at least a portion of the holilraumorgans in which the tip of the instrument is located.
- the disadvantage of this method is that only a continuous angiographically recorded angiographic image display is possible, but no link between preoperative and intraoperative recorded sectional image data can be done in real time.
- DE 102 10 647 A1 discloses methods for image presentation of a medical instrument, in particular a catheter, introduced into an examination area of a patient, in the context of a cardiological examination or treatment, with the following steps:
- DE 103 33 543 A1 discloses a method for the coupled representation of intraoperative and preoperative images in medical imaging with the following steps:
- a video sequence based on intraoperative images which have been recorded during a periodic physiological movement cycle at defined times and / or location points, is interpolated between the re-registered images from the pre-registered preoperative images. This will be in front of attached to the Aufbiiehmen the preoperative area markers, so that the registration of image data is based on markers.
- DE 10 2007 051 479 A1 discloses a method and a device for displaying image data of a plurality of image data sets during a medical, in particular abdominal, intervention, the method comprising the following steps:
- synchronous three-dimensional image representation in which at least one information of the two-dimensional image data set is transferred into the three-dimensional image data set by means of the registration, wherein the viewing angle or spacing of the integrated image representation on the target area different from the recording angle or Aumahme distance of the two-dimensional image data set on the Target area can be adjusted.
- a dual-monitor system for synchronous three-dimensional image display is used.
- the disadvantage of the method according to DE 10 2007 051 479 A1 is that it uses a data and image configuration that is not suitable for the CT-guided (or MRT- or US-guided) intervention.
- 2D projection data sets are generated which are used to control patient anatomy and tool position during the intervention and to register the spatial image information (3D datasets).
- This imaging geometry requires a Measurement order according to angiographic equipment, in which a planar projection lags of the patient is made.
- the patient is located between the radiator and the radiation detector (eg area detector or image intensifier).
- CT tomographic method
- this approach can not be used because no projection images (fluoroscopic images according to DE 10 2007 051 479 A1) are available.
- the generated data is 2D or 3D sectional image data.
- the disadvantage of this method is that it uses a data / image configuration that is not suitable for CT-guided (or MRI- or US-guided) intervention.
- the method is based on the use of 2D projection data (radiographic data sets) similar to the application DE 10 2007 051 479 A1.
- a 2D projection data set is calculated from a pre-interventional 3D slice image data set.
- the image information reduced to a 2D dataset is then displayed comparatively next to the interventional radiograph.
- the invention is therefore based on the object to provide a method that the combination of preoperatively recorded and stored high-resolution diagnostic 3-D image data of the target area of a patient with intraoperatively recorded during a medical intervention 2 -D- sectional image data of this target area of the patient continuously in real time during the intervention (navigation according to the "roadmap" principle). Moreover, it is the object of the invention to provide an arrangement for carrying out this method.
- Fig. 1 shows an arrangement for carrying out the method according to the invention. and the following definitions are used:
- Diagnostic image data are image data of a quality suitable for primary medical evaluation. With regard to these quality criteria, there are relevant requirements of the DIN (or international committees), the Association of Statutory Health Insurance Physicians and the German Medical Associations. Compliance with the criteria is the subject of comprehensive quality assurance and control by inspection bodies such. The concept of diagnostic image quality can be considered socially defined in the context of radiation application to the patient.
- the non-diagnostic image data is generated with identical imaging modalities (eg CT, MRT) which are also used for the production of diagnostic image data.
- CT computed tomography
- MRT machine learning modalities
- Only the Aufhahmeprotokolle are adapted so that they are recorded eg with significantly reduced measurement time or a significantly lower radiation dose is applied. This adaptation is done with the intent to use them for specific measurement task, here eg the use for fluoroscopic imaging techniques to display a dynamically changing image information.
- non-diagnostic 2D cut data (fluoroscopic data) is recorded permanently / continuously.
- the fluoroscopic 2D slice through the examination volume does not represent a frozen image information, but rather sees every change within the target volume. This change can be made both by a physiological process within the cutting plane, e.g. the intestinal movement or by advancing a tool for interventional purposes.
- the described invention focuses on the field of minimally invasive intervention.
- a tool e.g., a long needle
- a targeted region e.g., a tumor or tissue structure to be biopsied.
- the text passage "taking an image data set during the intervention” means imaging during these interventional actions, since the operator (doctor) is in the immediate vicinity of the patient and the imaging is part of the intervention over several minutes (until In the case of radiotherapy (CT-assisted intervention), a greatly reduced dose must be used, and parallel imaging is not intended to prolong the overall intervention excessively, so fluoroscopic imaging is always performed with adapted (accelerated ) Protocols at the cost of loss of diagnostic quality in the book.
- the presentation is a presentation of the results of coregistration of non-diagnostic 2D slice images (fluoroscopic image data) and pre-interventional diagnostic 3D image data.
- Parallel to the fluoroscopic 2D slice image the spatially corresponding image content of the 3D slice image data set or of several SD slice image data sets of the region to be treated is displayed parallel to the fluoroscopic 2D slice image.
- This selection process is performed by comparing the image information of the 2D fluoroscopic image data set with the 3D diagnostic dataset / datasets until a section through the 3D diagnostic data has been found indicating a minimal deviation.
- the coregistration of the diagnostic 3D data set with the fluoroscopic 2D slice image data set takes place permanently. This means that a change in the fluoroscopic 2D scintigraphic images acquired during the intervention, e.g. due to the changed position of the tool (needle), resulting in the representation of the appropriate cut by the diagnostic 3D slice data set.
- This procedure permanently compares the fluoroscopic 2D data with the diagnostic 3D data and thus always a current diagnostic presentation (office information) can present.
- the comparison does not have to be triggered and does not take place in discrete fixed time intervals.
- the update is limited only by the used computing power.
- the non-diagnostic dataset necessary for registration can also be prepared during the intervention in a non-fluoroscopic technique (e.g., by rotational angiography).
- a non-fluoroscopic technique e.g., by rotational angiography
- 3D or 2D 3D or 2D
- the registration of the image data takes place.
- This e.g. Record acquired by the rotation angio replaces the function of the fluoroscopic image in this case.
- the process of registration is controlled by the fluoroscopic 2D real-time slice image data. There is a continuous automated comparison of this data set with pre-interventionally prepared 3D datasets which are of diagnostic quality. As a result of this registration, one or more cutting planes are selected from the diagnostic data set which have the highest similarity in their image content to the fluoroscopic 2D real-time cut image data record.
- the arrangement shown in Fig. 1 consists of means (1) for storing recorded diagnostic 3-D Büd Scheme and for carrying out the dynamic coregistration, a device (2) for recording diagnostic 3-D image data sets, means (3) for Short-term recording of non-diagnostic 3-D image data sets and recording of 2-D real-time editing data, a device (4) for presenting the correspondence-processed diagnostic 3-D image data sets and a device (5) for presenting the 2-D images Real-time slice image data, these devices being data-connected to each other, in which there is a connection between the devices (1) and (2), (1) and (3) and (1), (4) and (5).
- the device (3) is a magnetic resonance tomograph, computer tomograph or ultrasound device for the short-term recording of non-diagnostic 3-D image data sets in combination with a fluoroscopic method for recording 2-D real-time image data.
- the device (4) according to the invention is a dual-monitor system and the device (1) is a computer.
- the arrangement shown in FIG. 1 is for carrying out a method for simultaneous, parallel, continuous display of stored, high-resolution 3-D diagnostic image data and 2-D real-time image data during a patient's medical intervention.
- the acquisition of the 3-D non-diagnostic image data set or the 2-D cross-sectional data set by computed tomography (CT), magnetic resonance imaging (MRI), C-arm X-ray or positron emission tomography (PET) within a limited time window of 0.1 to 5 seconds.
- CT computed tomography
- MRI magnetic resonance imaging
- PET positron emission tomography
- the recording of the 2-D slice image data set takes place in real time by computer tomography (CT) and magnetic resonance tomography (MRT) under fluoroscopic conditions or ultrasound.
- CT computer tomography
- MRT magnetic resonance tomography
- the information of the 3-D diagnostic image data set, the 3-D non-diagnostic image data set and the 2-D sectional data set are computationally and automatically coregistered by means of a computer according to the invention.
- the advantage of the invention is the continuous linking of preoperatively acquired and stored high-resolution 3-D diagnostic image data of the target area of a patient with intraoperatively acquired 2-D slice image data of this target area of the patient in real-time during the intervention (navigation after the ,, roadmap "principle).
- the device according to the invention and the method according to the invention also enable the insertion of additional information, such as, for example, the preliminary planning of the position of irradiation katliedern in order to allow for a later brachytherapy an optimized treatment plan.
- additional information such as, for example, the preliminary planning of the position of irradiation katliedern in order to allow for a later brachytherapy an optimized treatment plan.
- the information displayed here serves to guide the surgeon / interventional radiologist when inserting the catheters.
- the device according to the invention and the method according to the invention lead to a significant increase in the precision of microtherapeutic interventions as well as to a minimization of risks during these interventions through a better localization (thus, as it were, a navigational support of the surgeon).
