Engineering Contradiction Analysis
1Productivity
If two-dimensional medical images are displayed, then the display device can show medical data, but medical personnel require complicated operations to obtain scan results quickly
Solution Approach 1:
The patent transitions from two-dimensional medical image display to three-dimensional volume data visualization. By rendering 3D models from volumetric scan data, the system enables medical personnel to view and interact with anatomical structures in their natural three-dimensional space, eliminating the need for complex multi-step operations to obtain scan results while maintaining comprehensive diagnostic information.
2Ease of operation
If three-dimensional image processing is implemented, then rapid and intuitive viewing is achieved, but coordinate system conversion and data processing complexity increases
Solution Approach 1:
The patent introduces a coordinate system conversion module as an intermediary between the scan data acquisition phase and the 3D rendering phase. This module automatically transforms coordinates from the scan device's coordinate system to the display device's coordinate system, handling the technical complexity of coordinate conversion internally while presenting users with simple intuitive interaction controls for 3D viewing.

AI summary
A three-dimensional image display method includes the following. A display device coordinate system is established. First volume data is obtained, and multiple first coordinates of multiple voxels of the first volume data in an absolute space coordinate system are defined. Coordinates of a reference point of the first volume data are aligned with a reference point in the display device coordinate system, so that the multiple first coordinates of the multiple voxels of the first volume data are converted to the display device coordinate system to generate second volume data. A plurality of pieces of sampling data of a plurality of pixels corresponding to the display device are determined according to a plurality of light projection paths, so as to generate display data. An image is displayed according to the display data through the display device, and the image is viewed by human eyes as a 3D object image.
