Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical imaging technologies, such as CT scans, struggle with providing radiologists with an efficient and effective means to visualize multiple slices and construct a holistic three-dimensional representation of patient data, leading to time-consuming and labor-intensive processes due to limitations in depth perception and tissue anomaly detection.
Innovation Solution
The development of a method that combines slices from medical imaging devices to create a volume of interest, allowing for three-dimensional representation on a Head Display Unit (HDU), enabling rotation, tissue subtraction, color schematic identification, and zooming capabilities to facilitate unobstructed viewing and depth perception.

Engineering Contradiction Analysis
1Measurement precision
If multiple CT slices are viewed individually on conventional monitors, then detailed examination of each slice is possible, but the process is time-consuming and labor-intensive
Solution Approach 1:
The patent combines multiple individual CT slice views into a single integrated three-dimensional volumetric representation displayed on one monitor. This merging allows radiologists to examine detailed anatomical structures across multiple slices simultaneously without manually switching between individual slice displays, thereby reducing viewing time while maintaining diagnostic precision.
Solution Approach 2:
The patent transitions from two-dimensional slice-by-slice viewing to a three-dimensional volumetric display. By adding the depth dimension and enabling rotation around the z-axis, the system provides a holistic view of anatomical structures that encompasses all slices, allowing rapid comprehensive examination without sacrificing detailed analysis capability.
2Device complexity
If conventional two-dimensional displays are used, then simple display mechanisms are sufficient, but depth perception and holistic visualization are limited
Solution Approach 1:
The patent enhances conventional two-dimensional displays by incorporating three-dimensional volumetric rendering capabilities. The system displays multiple slices stacked along the z-axis and enables rotation around this axis, creating a pseudo-3D effect that provides depth perception and holistic visualization while still using standard monitor hardware, thus minimizing device complexity additions.
Solution Approach 2:
The patent introduces dynamic rotation capability around the z-axis, allowing the volumetric display to be rotated interactively. This dynamic feature enables radiologists to view anatomical structures from multiple angles and gain depth perception without requiring complex static three-dimensional display hardware, maintaining relative simplicity while significantly improving information presentation.
3Measurement precision
If individual slices are examined separately, then each slice can be analyzed in detail, but constructing a holistic three-dimensional representation is difficult
Solution Approach 1:
The patent merges multiple individual slice analyses into a single integrated three-dimensional volumetric display. By stacking slices along the z-axis and enabling rotation, the system automatically constructs the holistic representation, eliminating the need for radiologists to manually piece together multiple slices and significantly improving ease of operation.
Solution Approach 2:
The patent creates a virtual three-dimensional copy of the anatomical structure by computationally reconstructing the volumetric data from multiple slices. This virtual model can be rotated and examined from any angle, providing an intuitive holistic view that preserves the detailed information from each individual slice while presenting it in an easily interpretable format.

AI summary
A method and apparatus for three dimensional viewing of images is presented. Left eye viewing point (LEVP) imagery is passed through a left eye filter to obtain a filtered LEVP imagery. Right eye viewing point (REVP) imagery is passed through a right eye filter to obtain a filtered REVP imagery. The filtered LEVP imagery is projected on a display and the filtered REVP imagery is projected on the display. A user wearing polarized glasses is able to view the filtered LEVP imagery and the filtered REVP imagery as three-dimensional imagery on the display. The three dimensional imagery can be augmented.
