Embodiment Construction

[0014] The specific steps of the method of the present invention are as follows: (1) Read in original medical CT or MRI data and perform three-dimensional reconstruction. (2) Perform data segmentation to obtain the part of the pipeline organs of interest. (3) Find the central skeleton. (4) Obtain part of the characteristic cross-section perpendicular to the central skeleton and obtain its characteristic perimeter. (5) Obtain the characteristic surface area of ​​the organ. (6) Perform image deformation to make the image meet the constraints and obtain the maximum volume. The technical solution of the present invention will be described in further detail below with reference to a specific embodiment.

[0015] In this embodiment, the CT slice data of the lower abdomen of the human body without inflating the colon is used as a sample, in order to obtain the colon data after virtual inflation. The realization process of the whole invention process is as follows:

Abstract

A virtual inflation method for improving the visualizing effect of hollow viscus includes such steps as finding out the central skeleton of whole viscus according to the body data of obtained and divided hollow viscus, creating its constraint conditions, and deforming the image of viscus to make it have maximal volume, so obtaining the image of virtually inflated viscus.

Description

technical field [0001] The invention relates to a method in the technical field of image processing, in particular to a method for improving the visualization effect of hollow organs with virtual inflation. Background technique [0002] At present, using CT, MRI and other medical imaging data, virtual endoscopy technology is mainly used to reconstruct the inner wall of hollow organs such as colon, stomach, trachea, etc. for 3D visualization and clinical diagnosis. This technology simulates the travel of the traditional optical endoscope in the lumen, and observes and diagnoses from the perspective of the optical endoscope. The advantage of this technique is that it is a non-invasive method that is less painful for the patient. [0003] The literature search of the prior art found that in the article "Research on the Development and Application of 3D Human Virtual Endoscopy" published by Ye Jianjiang in "Medical Equipment Information" (2002, No. 6, pp. 48-50), he introduced ...
