Embodiment 1

[0046] see Figure 5 , this embodiment takes figure 1 The CT scan of the lateral sesamoid of the first metatarsal of the right foot is shown as an example to specifically illustrate the steps included in the method for mapping the surface of human organs based on tomographic image reconstruction described in this embodiment.

[0047] (1) Reconstruction: For the image obtained by CT tomography, the main axis of inertia of the sesamoid bone is found by geometric transformation, and the axis of inertia is used as the body coordinate of the sesamoid bone, and then the tomographic reconstruction is performed.

[0048] The specific steps for tomographic reconstruction are:

Abstract

The invention discloses a human organ surface mapization method based on sectional image reconstruction. For a human organ based on sectional image reconstruction, drawing factors such as the prime meridian and the contour line of an organ map are determined according to the inertia principal axis of the organ, and organ surface mapization is achieved by using methods such as sectional image reconstruction and sectional boundary development. Quantitative study can be provided for morphological analysis on the organ surface.

Description

technical field [0001] The invention relates to the field of medical image processing, in particular to a method for mapping the surface of human organs based on tomographic image reconstruction. Background technique [0002] The tomographic images mainly include CT, MRI, etc. At present, the tomographic images have been widely used in the field of organ morphology research. The processing methods of tomographic images include image segmentation, morphological processing, three-dimensional imaging, etc. Through image processing and morphometric measurement, the change of the detected object over time can be analyzed, such as the growth, development and aging of human organs and other morphological studies. [0003] At present, the tomographic images obtained by methods such as CT tomography are all three-dimensional images, which are not intuitive enough for viewing and analysis. At the same time, when comparing with the images taken before, it is not easy to find the diff...
