Title: Program and method concerning visualization of luminal organ
Inventor: CHEN CHAO-CHENG
IPC: A61B6/03
Filed: 2022-02-25
Abstract: To provide a program and method concerning visualization of a luminal organ, for visualizing and manipulating the internal structures of a tubular object without any noticeable distortion based on the center line of the tubular object.SOLUTION: In many practical applications such as medical clinic, the assessment of the internal structures of tubular objects is a very important topic. Many 3D visualization techniques have been used for visualization of the internal structures of an organ. However, the visualization techniques are not capable of projecting an actual length and is capable of generating only a very distorted 3D luminal organ. This invention automatically calculates the shell of a 3D tubular object and divides the object into a plurality of segments based on the center line of the shell. Each segment is columnar and used as a basic operation unit to simply cut and open or notch the object to observe the internal structure. This makes it possible to visualize the internal structure of the object without distortion. In many medical applications, this can be used for diagnosis, planning of surgery, or stent placements, etc., and consequently improves the quality of healthcare significantly.SELECTED DRAWING: Figure 5A
