Description

  The present invention relates to a spinal slice image display apparatus, method, and program, and more particularly to a spinal slice image display apparatus, method, and program for generating and displaying a cross-sectional image of a vertebra part based on three-dimensional image data.

  In recent years, with the progress of imaging apparatuses (modalities), the resolution of image data captured by the imaging apparatus has been improved, and detailed analysis of a subject can be performed based on the image data. For example, multi-slice CT (Multi Detector-row Computed Tomography) can take a plurality of tomographic images at a time, and can take a tomographic image with a thin slice thickness. By reducing the slice thickness, the resolution in the body axis direction of the three-dimensional image data obtained by stacking a plurality of tomographic images increases, and more detailed three-dimensional image data can be obtained.

  Using the above three-dimensional image data, the vertebra structure can be analyzed. For example, Patent Document 1 describes obtaining a center line of a vertebra by analyzing three-dimensional image data. Further, in Patent Document 1, the corpus cavernosum region in the body axis direction of each vertebral body constituting the vertebra is estimated and estimated based on the pixel value (voxel value) of the specific region existing near the centerline of the vertebra. The feature value of the pixel value of the specific region is calculated in the corpus cavernosum area of each vertebral body, the three-dimensional center of the corpus cavernosum area of each vertebral body is detected based on the feature quantity, and based on the detected three-dimensional center The calculation of the positions of both ends of each vertebral body in the body axis direction is described. Further, the cited document 1 describes that an intermediate point between the three-dimensional centers of the cavernous regions of two adjacent vertebral bodies is the intervertebral portion of the two vertebral bodies.

  The slice position moving means may divide the distance on the center line between the adjacent intervertebral discs into a predetermined number at equal intervals, and take each of the divided positions on the center line as the slice position. It may be a coordinate position.

  The slice position moving means sets the position of each intervertebral disk as a position of 0%, the position of the intervertebral disk adjacent to the intervertebral disk as a position of 100%, and from the position of 0% to 100% for each of the plurality of cross-sectional images. The slice position may be moved between the positions.

  The slice position moving means may give the position between adjacent vertebral bodies to the cross-sectional image generating means as an initial slice position.

  The cross-sectional image display means may be configured to identify a position where the size of the vertebral body is equal to or smaller than a predetermined reference, and to highlight the cross-sectional image corresponding to the identified position.

  In the above case, the cross-sectional image display means may determine whether or not the size of the vertebral body is below a reference by comparing the sizes of adjacent vertebral bodies with each other.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a vertebra cross-sectional image display apparatus according to an embodiment of the present invention. The vertebra cross-sectional image display device 10 includes an image input unit 11, a center line detection unit 12, an intervertebral disc detection unit 13, a cross-sectional image generation unit 14, a cross-sectional image display unit 15, and a slice position moving unit 16. The function of each part in the vertebra cross-sectional image display device 10 can be realized by a computer executing processing according to a predetermined program.

  The image input means 11 inputs 3D image data including vertebrae (hereinafter also simply referred to as 3D data) and stores it in the 3D data storage unit 21. The centerline detection means 12 detects a centerline along the shape of the vertebra based on the three-dimensional data, and stores the detected centerline information in the centerline storage unit 22. The intervertebral disc detection means 13 detects the intervertebral disc position between adjacent vertebral bodies based on the three-dimensional data, and stores the detected intervertebral disc position information in the intervertebral disc position storage unit 23.

  The cross-sectional image generation unit 14 refers to the three-dimensional data storage unit 21 and the centerline storage unit 22 and generates a cross-sectional image obtained by slicing the vertebra with a cross section perpendicular to the centerline based on the three-dimensional data. The cross-sectional image generating means 14 generates a plurality of cross-sectional images obtained by slicing a vertebra with a cross section perpendicular to the center line passing through the slice position, with a plurality of positions on the center line of the vertebra as slice positions. The slice image display means 15 displays a plurality of slice images generated at a plurality of slice positions side by side on the display screen of the display monitor 31.

  The slice position moving unit 16 moves the slice position of the cross-sectional image generated by the cross-sectional image generating unit 14 along the center line of the vertebra. The slice position moving means 16 moves the slice positions of a plurality of cross-sectional images in conjunction with the vertebra centerline, for example. In other words, the slice position moving means 16 moves the slice positions of the plurality of cross-sectional images in synchronization with each other along the center line of the vertebra. When the slice position moving unit 16 moves the slice position, the cross-sectional image generating unit 14 generates a cross-sectional image obtained by slicing the vertebra with a cross section perpendicular to the center line at each slice position after the movement.

  FIG. 2 shows a screen display example. The area on the left side of the drawing is an area where a cross-sectional image of the entire vertebra is displayed. The area on the right side of the drawing is an area where a cross-sectional image at the position of the vertebral body or intervertebral disk constituting each vertebra is displayed. The cross-sectional image display means 15 displays, for example, the cross-sectional images of all vertebral bodies or intervertebral discs side by side on the display screen. Or the cross-sectional image display means 15 may arrange and display the cross-sectional image of arbitrary vertebral bodies or intervertebral discs among the vertebral bodies and intervertebral discs constituting the vertebrae on the display screen. The cross-sectional image display means 15 may display, for example, cross-sectional images of vertebral bodies or intervertebral discs of cervical vertebrae and lumbar vertebrae.

  FIG. 3 shows the detected center line. The center line detection means 12 detects a line passing through the approximate center of each vertebral body constituting the vertebra as a center line. Any technique can be used to detect the centerline of the vertebra. The detection of the center line of the vertebra may be performed manually by a human. The detection of the center line is not necessarily performed in the vertebra cross-sectional image display device 10, and information on the center line can be input from the outside together with the three-dimensional data. In the present specification, the term “center line” is used for convenience, but the center line of the vertebra need only be along the shape of the vertebra, and need not necessarily be a line passing through the center of the vertebra.

  FIG. 4 shows the position of the detected intervertebral disc. The intervertebral disc detection means 13 detects, for example, between adjacent vertebral bodies as an intervertebral disc. Any technique can also be used to detect the intervertebral disc. The detection of the intervertebral disc may be performed manually by a human. In addition, the detection of the intervertebral disc does not necessarily have to be performed in the vertebral cross-sectional image display device 10, and it is also possible to input intervertebral disc positional information together with the three-dimensional data.

  The slice position moving means 16 can provide the cross-sectional image generating means 14 with the position between adjacent vertebral bodies, that is, the position of the intervertebral disc as the initial slice position. The slice position moving means 16 can set coordinates along the center line between adjacent intervertebral discs and move the slice position according to the coordinates. At that time, the slice position moving means 16 can set coordinates according to the distance on the center line of the vertebra between the adjacent intervertebral discs. For example, the slice position moving means 16 divides the distance on the center line between adjacent intervertebral discs by a predetermined number of divisions, and each of the divided positions on the center line can be taken as a coordinate position (slice point) that can be taken as a slice position. can do.

FIG. 5 illustrates coordinate settings. In the figure, the center line of the vertebra is represented by a straight line. Consider three intervertebral discs i-1, i, i + 1 (i is an arbitrary natural number). The distance between the center line of the disc i-1 to the disc i and d i-1, the distance on the center line from the disc i to the disc i + 1 and d i. The number of divisions is 5. The slice position moving means 16 sets the position of the intervertebral disc i-1 as the coordinate position 0, and advances the coordinate position 1, the coordinate position 2, the coordinate position 3, each time it proceeds d i-1 / 5 from the position toward the position of the intervertebral disc i. Coordinate position 4 is set. Similarly, between the intervertebral disk i and the intervertebral disk i + 1, the slice position moving means 16 sets the position of the intervertebral disk i as the coordinate position 0, and advances the coordinate position 1, the coordinate position 2, the coordinate position 3, the coordinate position every time the distance d i / 5 4 is set. The coordinate setting described above is an example, and the coordinate setting method is not limited to this.

In the initial state, the cross-sectional image generation unit 14 generates a cross-sectional image at the position of each intervertebral disc, that is, at the coordinate position 0 described above. When the user performs an operation of advancing the slice position, the slice position moving unit 16 changes the slice position with respect to each intervertebral disc from the coordinate position 0 to the coordinate position 1. The cross-sectional image generation unit 14 moves the slice position to the coordinate position 1 and generates a cross-sectional image. In the above case, the cross-sectional image generating means 14 for the intervertebral disc i-1, the slice position is advanced by d i-1 / 5 along the center line from the position of the intervertebral disc i-1. Then, for the intervertebral disc i, a slice image is generated at a position where the slice position is advanced by d i / 5 from the position of the intervertebral disc i along the center line. By moving the coordinate positions in synchronization with each intervertebral disc position, the position of the cross section displayed in each cross-sectional image can be moved in conjunction with each other.

  Here, when the position of each intervertebral disc is 0% and the position of the intervertebral disc adjacent to the intervertebral disc is expressed as 100%, the coordinate position 1 is 20%, and the coordinate position 2 is 40%. Position, coordinate position 3 can be expressed as 60% position, and coordinate position 4 can be expressed as 80% position. When performing the coordinate setting as described above, positions (slice points) on the center line that can be taken as slice positions are set discretely as a 20% position, a 40% position, a 60% position, and an 80% position. It will be. Instead of discretely setting the slice points, it is also possible to arbitrarily set the slice position between 0% position and 100% position for each of the plurality of cross-sectional images.

  FIG. 6 shows an operation procedure. The image input means 11 inputs 3D data and stores it in the 3D data storage unit 21 (step S1). The center line detection means 12 detects the center line of the vertebra based on the three-dimensional data, and stores the detected center line information in the center line storage unit 22 (step S2). The intervertebral disc detection means 13 detects the intervertebral disc position based on the three-dimensional data, and stores the detected intervertebral disc position information in the intervertebral disc position storage unit 23 (step S3). Steps S2 and S3 may be omitted when centerline information and intervertebral disc position information are given from the outside.

  The cross-sectional image generating means 14 generates a cross-sectional image obtained by slicing a vertebra with a cross section perpendicular to the center line passing through the initial slice position, with the position of each intervertebral disc on the center line as the initial slice position (step S4). The slice position moving means 16 may set the initial slice position. The slice plane of the cross-sectional image generated by the cross-sectional image generating unit 14 does not have to be strictly perpendicular to the center line of the vertebra, and may be slightly deviated from the vertical. The cross-sectional image display means 15 displays the generated cross-sectional images side by side on the display screen of the display monitor 31.

  The slice position moving means 16 sets coordinates between the adjacent intervertebral discs (step S5). In step S5, the slice position moving unit 16 sets coordinate positions (slice points) that can be taken as slice positions between the intervertebral discs. The slice position moving means 16 sets the same number of slice points between each intervertebral disc regardless of the distance between adjacent discs. The slice position moving means 16 sets five slice points including the initial slice position for each intervertebral disc, for example.

  The slice position moving unit 16 receives an instruction to move the slice position (step S6). The user instructs to move the slice position, for example, by rotating a mouse wheel. When the user instructs to move the slice position, the slice position moving unit 16 moves the slice position to a slice position different from the slice position of the current cross-sectional image (step S7). At this time, the slice position moving means 16 moves the slice position to one of the coordinate positions set in step S5. The slice position moving means 16 moves, for example, the slice position of each cross-sectional image to a coordinate position corresponding to each other.

  The cross-sectional image generation unit 14 generates a cross-sectional image at the moved slice position (step S8). The cross-sectional image display means 15 displays the cross-sectional images whose slice positions have been changed side by side on the display screen of the display monitor 31. The slice position moving means 16 determines whether or not the process is finished (step S9). When the processing is not finished, the slice position moving means 16 returns to step S6 and accepts an instruction to move the slice position. The slice position moving unit 16 moves the slice position every time the user instructs to move the slice position, and the cross-sectional image generating unit 14 generates a cross-sectional image at the moved slice position. If it is determined in step S9 that the process has ended, the process ends.

  FIG. 7 shows a specific example of the coordinate position set in step S5. Here, consider four discs, intervertebral disc i to intervertebral disc i + 3. The vertebral body i between the intervertebral disc i and the intervertebral disc i + 1, the vertebral body i + 1 between the intervertebral disc i + 1 and the intervertebral disc i + 2, and the vertebral body i + 2 between the intervertebral disc i + 2 and the intervertebral disc i + 3. Intervertebral body i + 3. The slice position moving means 16 divides the space between the adjacent intervertebral discs into four, and sets the coordinate position 1, the coordinate position 2, and the coordinate position 3 between the adjacent intervertebral discs (each vertebral body).

  FIG. 8A shows an initial slice position, and FIG. 8B shows a cross-sectional image at the initial slice position. In step S4, the cross-sectional image generation unit 14 generates a cross-sectional image at the position of the intervertebral disc that is the initial slice position. The initial slice position is indicated by a dotted line in FIG. 8A. This initial slice position corresponds to each coordinate position 0 in FIG. The sectional image display means 15 displays the sectional images at the positions of the four intervertebral discs side by side. The user diagnoses the presence or absence of abnormality by comparing and observing the displayed cross-sectional images.

  In step S6, when the user instructs to change the slice position, the slice position moving unit 16 moves the slice position from the initial slice position to, for example, the position of each coordinate position 1 in FIG. FIG. 9A shows the slice position after movement, and FIG. 9B shows a cross-sectional image at the slice position after movement. The slice position moving means 16 moves the slice position from the position of each intervertebral disc to the coordinate position 1 as shown in FIG. 9A. The cross-sectional image generation unit 14 generates four cross-sectional images at the slice position after movement, and the cross-sectional image display unit 15 displays the generated four cross-sectional images side by side as shown in FIG. 9B.

  When the user further changes the slice position, the slice position moving means 16 moves the slice position to the position of each coordinate position 2 in FIG. 7, for example. FIG. 10A shows a slice position after further movement, and FIG. 10B shows a cross-sectional image at the slice position after the movement. The slice position moving means 16 moves the slice position to the coordinate position 2 as shown in FIG. 10A. The cross-sectional image generation unit 14 generates four cross-sectional images at the slice position after movement, and the cross-sectional image display unit 15 displays the generated four cross-sectional images side by side as shown in FIG. 10B. The user can arbitrarily move the slice position between the coordinate position 0 and the coordinate position 3. It is also possible to display a cross-sectional image at each slice position as a moving image like an animation. The user can observe a cross-sectional image at an arbitrary coordinate position by arbitrarily moving the slice position.

  In the present embodiment, the slice position moving unit 16 moves the slice positions of the plurality of cross-sectional images generated by the cross-sectional image generating unit 14 along the center line of the vertebra. The cross-sectional image generation means 14 generates a plurality of cross-sectional images of the vertebra at the moved slice position, and the cross-sectional image display means 15 displays the generated cross-sectional images side by side so that the user can The cross section of the vertebra can be observed at any position. When the slice position moving means 16 is configured to move the slice positions of a plurality of cross-sectional images in conjunction with the center line of the vertebra, the slice positions of the plurality of cross-sectional images displayed side by side can be moved simultaneously. .

  By the way, when a compression fracture or the like occurs in the vertebra, the size of the vertebral body is considered to be smaller than that of other vertebral bodies. The cross-sectional image display means 15 may specify a position where the size of the vertebral body is equal to or smaller than a predetermined reference, and highlight the cross-sectional image corresponding to the specified position. Whether or not the size of the vertebral body is below the reference can be determined by comparing the distance between adjacent vertebral bodies with a predetermined threshold value, for example. Alternatively, even if the distance between the intervertebral discs is compared between adjacent positions and the distance between the intervertebral discs is shorter than the distance between the other intervertebral discs, Good.

  FIG. 11A shows a vertebra when there is a compression fracture, and shows a display example of a cross-sectional image when there is a compression fracture. The cross-sectional image display means 15 detects a location where the distance between adjacent intervertebral discs is shorter than the distance between adjacent intervertebral discs in the periphery, and in the region on the right side of the display screen shown in FIG. As shown in FIG. 11A, a portion where the distance between the intervertebral discs is shortened can be highlighted, for example, in red. Further, in the area on the left side of the display screen shown in FIG. 2, the cross-sectional image corresponding to the portion where the distance between the intervertebral discs is short is highlighted, for example, by surrounding it with a red line. In this case, the user can easily find, for example, a place where a compression fracture has occurred.

  In the above embodiment, the example in which the position of the intervertebral disc is detected and the slice position is determined based on the position has been described. However, the present invention is not limited to this. For example, each vertebral body constituting the vertebra may be detected from the three-dimensional data, and the slice position may be determined based on the position. For example, the slice position moving means 16 sets the center position of each vertebral body as the initial slice position, sets coordinates between adjacent vertebral bodies according to the distance between the centers, and sets the slice position from the initial slice position. You may move according to a coordinate.

  The movement range of the slice position is not limited between adjacent vertebral bodies. The moving range of the slice position can be arbitrarily set. For example, when the position of the intervertebral disc i (FIG. 5) is set as the initial slice position, a position separated from the intervertebral disc i by a distance on the intervertebral disc i-1 side and a position separated from the intervertebral disc i by a distance on the intervertebral disc i + 1 side. Coordinates may be set between them, and the slice position may be moved within that range. In this case, for example, the position of the intervertebral disc i may be set as the coordinate position 0, the position on the intervertebral disc i-1 side may be set as a negative coordinate position, and the position on the intervertebral disc i + 1 side may be set as a positive coordinate position.

  Although the present invention has been described based on the preferred embodiments, the cross-sectional image display device, method, and program of the present invention are not limited to the above embodiments, and various configurations are possible from the configuration of the above embodiments. Those modified and changed as described above are also included in the scope of the present invention.
