Definitions
- the present invention relates to the field of digital imaging.
- the present invention relates to a method of visualizing a multi-dimensional data set, to an image processing device, to imaging systems and to a computer program for performing a visualization of a multi-dimensional data set.
- Both endoscopy and biopsy are important techniques in medical diagnosis. It is often only possible to determine the origin of a symptom or a sign of an early phase of disease by visually examining the inside of the living human body or by taking tissue probes from the inside of the living human body. Every year thousands of endoscope procedures are carried out.
- Optical endoscopy is a medical procedure used to examine hollow organs or a cavity inside a human body.
- a medical procedure may be performed which, for diagnostic treatment purposes, removes a sample of an object of interest, such as a piece of tissue of a specific internal organ by inserting a medical device into the patient's body and, at the same time, monitoring the movement of the medical device by means of, e.g., an ultrasound imaging system.
- an object of interest such as a piece of tissue of a specific internal organ
- monitoring the movement of the medical device by means of, e.g., an ultrasound imaging system.
- the choice of the visualization method and orientation is crucial for the intervention success.
- in real-time tasks there is only one chance to display the volume in the most useful manner.
- Volume display is a challenging task due to the large amount of three- dimensional information that has to be displayed on a screen in two dimensions. All visualization methods of three-dimensional data ignore much of the acquired information. For example, with surface shading many image voxels are hidden in the image, which is displayed on the screen. Similarly, the maximum intensity projection, on each projected ray only the contribution of one voxel is displayed.
- One question occurring is what to ignore and what to show in real-time applications, since user control may not be possible or may put an undue burden on the user, since the physician is fully concerned with operating his interventional devices.
- the above object may be solved by a method of visualizing an multi- dimensional data set, wherein the method comprises the steps of performing a segmentation of a structure in the data set and performing a visualization of the data set, wherein a projection direction of the vis ⁇ alization is determined on the basis of the structure.
- a structure in a data set may be identified by a segmentation procedure and, depending on the segmented structure, an image slice or projection of the data set is visualized, wherein the position of the projection inside the data set is related to the structure.
- this may allow for an automated choice of parameters of the visualization procedure and therefore for an improved visualization.
- the visualization is performed on the basis of visualization parameters which comprise information about the projection direction and which are determined on the basis of at least one of the segmentation of the structure in the data set and low-level analysis of the data set.
- the visualization parameters are selected from the group consisting of a relative position of the structure, a direction relative to the structure, a distance between the structure and an object of interest, a motion estimation, and a motion compensation.
- image slices may be visualized in a certain direction relative to the structure and, for example, at a certain distance from the structure.
- the multi-dimensional data set may comprise data relevant for motion estimation or compensation, such as, for example, electro-cardiogram (ECG) data.
- ECG electro-cardiogram
- This additional data may be used, e.g., for a motion compensated visualization of the data set.
- the structure is one of a biopsy needle and an endoscope probe, wherein a first projection of the data set is performed in a direction of a longitudinal axis of the structure, resulting in a first image with an image surface area perpendicular to the direction of the longitudinal axis. Furthermore, a second projection of the data set is performed in a direction perpendicular to the longitudinal axis of the structure, resulting in a second image comprising the structure.
- this may provide for a first image slice visualizing a viewing direction of a biopsy needle and a second image slice visualizing the biopsy needle itself and data on a plane comprising the biopsy needle.
- the method further comprises the step of varying a rendering method in an image resulting from the visualization of the data set, wherein the variation of the rendering method causes a non-uniform quality of the image.
- the variation of the rendering method comprises a variation of a sampling rate in the image and the variation of the rendering method is performed on the basis of the visualization parameters.
- this may allow for maximum image quality in the centre of an image slice (where the biopsy needle may be pointed to), and, at the same time, for a reduced image quality at the edges of the image slice (which are not of high interest to the user).
- this may provide for a reduction of computational cost.
- the segmentation is performed on the basis of one of a Hough Transform and a determination of active localizers.
- the data set is acquired by means of an ultrasound imaging system, a CT imaging system and an MR imaging system.
- an image processing device for visualizing a multi-dimensional data set comprising a memory for storing the data set and an image processor adapted for performing the following operation: loading the data set; performing a segmentation of a structure in the data set; and performing a visualization of the data set.
- the projection direction of the visualization is determined on the basis of the structure.
- this may allow for an improved visualization.
- the present invention also relates to imaging systems comprising a memory for storing a multi-dimensional data set and an image processor adapted for performing a visualization of the data set.
- the imaging system is one of an MR imaging system, a CT imaging system, and an ultrasound imaging system.
- the imaging systems according to the present invention are set forth in claims 11 to 13.
- this may allow for an improved visualization of a multidimensional data set acquired by a CT imaging system, an MR imaging system or an ultrasound imaging system.
- the present invention also relates to a computer program, which may, for example, be executed on a processor, such as an image processor.
- Such computer programs may be part of, for example, a CT scanner system, an MR scanner system or an ultrasound imaging system.
- the computer programs are set forth in claim 14. These computer programs may be preferably loaded into working memories of image processors or general purpose computers. The image processors are thus equipped to carry out exemplary embodiments of the methods of the present invention.
- the computer programs may be stored on a computer readable medium, such as a CD-ROM.
- the computer programs may also be presented over a network, such as the Worldwide Web and may be downloaded into the working memory of an image processor from such networks.
- the computer program according to this exemplary embodiment of the present invention may be written in any suitable programming langruage, such as C++.
- an intervention (caused by a user) to an object of interest is visualized without the requirement of an interactive input by the user, which may be a physician.
- parameters for a visualization procedure such as, e.g., of viewing direction, may be automatically chosen during data acquisition which may allow for an efficient tracking of the actual orientation and relative position of a structure, such as a biopsy needle, with respect to the object of interest, such as, for example, a cyst inside the abdomen or a plastoma or neoplasm inside the uterus of a patient.
