Embodiment 2

[0117] In the process of mapping the vertebral points in each frame of 2D medical images to the vertebral panorama, in order to improve the display effect of the mapped vertebral panorama, this embodiment provides a medical image processing method, see Figure 7 , Figure 7 It is a schematic flow chart of the medical image processing method in Embodiment 2 of the present invention, as Figure 7 As shown, the medical image processing method includes:

[0118] S21: Acquire rib points in the 3D medical image.

[0119] S22: Determine the center point (x 0 ,y 0 ), x 0 The x-coordinate associated with the rib point, y 0 The y-coordinate associated with the rib point, the X-axis is normal to the sagittal plane, and the Y-axis is normal to the coronal plane.

[0120] S23: Obtain a vertebra detection frame in any frame of 2D medical image.

[0121] S24: Translate the vertebra detection frame in each frame of the acquired 2D medical image to obtain a corresponding translated vert...

Embodiment 3

[0134] The difference between this embodiment and the foregoing embodiments is that in this embodiment, the panoramic view of the vertebrae is also displayed while the panoramic view of the ribs is displayed.

[0135] Figure 8 It is a schematic flow chart of the medical image processing method of the third embodiment of the present invention, as Figure 8 As shown, the medical image processing method includes:

[0136] S31: Obtain rib points in the 3D medical image.

[0137] S32: Determine the center point (x 0 ,y 0 ), x 0 The x-coordinate associated with the rib point, y 0 The y-coordinate associated with the rib point, the X-axis is normal to the sagittal plane, and the Y-axis is normal to the coronal plane.

[0138] S33: Obtain rib information in any frame of 2D medical image, where the rib information includes: the direction of the line between the center point and each rib point in the frame of 2D medical image, and the Z coordinate of the rib point.

Abstract

The invention discloses a medical image processing method. The method comprises the steps of acquiring rib points in a 3D medical image; determining a central point (x0, y0), x0 being associated withthe x coordinate of a rib point and y0 being associated with the y coordinate of a rib point; obtaining vertebra information in any frame of 2D medical image, wherein the vertebra information including the direction of a straight line where the central point and each vertebra point in the frame of 2D medical image are located, the Z coordinate of the vertebra point, the vertebra point being located on a first line segment or a second line segment which is parallel to the first line segment and is a preset distance away from the first line segment; and the first line segment passes through thecenter of the vertebra detection frame of the 2D medical image and is parallel to the X axis; and mapping the vertebra information in the multiple frames of 2D medical images to a first coordinate system to obtain medical images corresponding to the multiple frames of 2D medical images. According to the scheme of the invention, mapping efficiency and mapping accuracy are improved, and doctor filmreading and diagnosis are facilitated, so that diagnosis efficiency and diagnosis accuracy of doctors are improved to a certain extent.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a medical image processing method. Background technique [0002] At present, X-ray photography equipment, computer tomography (Computed Tomography, CT) equipment, nuclear magnetic resonance imaging (Nuclear Magnetic Resonance Imaging, NMRI) equipment, etc. can collect cross-sectional images (also called 2D images) of various parts of the human body, and can also Generate 3D images of various parts of the human body. [0003] At this stage, the cross-sectional images collected by medical imaging equipment usually cannot correspond to the panorama, so manual judgment is required to match the tissue in the cross-sectional image with the tissue in the panorama. Taking the collected chest image as an example, the chest image includes vertebrae. When a frame of cross-sectional image of the chest is collected, the doctor can judge based on experience which vertebra in the frame of cro...
