Solution Overview

Problem

Current methods for reconstructing 3D medical image datasets based on a cubic field of view often result in anatomical and medical objects along the viewing direction overlaying and obscuring objects of interest, complicating procedure planning and diagnosis.

Innovation Solution

A computer-implemented method that captures a dataset of anatomical and medical objects, identifies the objects being viewed by a viewer through a capturing signal, and adjusts the graphical display parameters to enhance visibility of the objects of interest, allowing for improved visualization and identification of foreground objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If a cubic field of view is used for 3D reconstruction, then the complete anatomical and medical objects can be captured, but objects along the viewing direction overlay and obscure objects of interest

Engineering Contradiction:
Improvecompleteness of captured objectsVSAvoidvisibility of objects of interest
Core Design Contradiction:
Quantity of substanceVSLoss of information

Solution Approach 1:

The patent introduces a fourth dimension (time) to the traditional 3D cubic field of view, creating a dynamic 4D visualization space. Objects are arranged not only in spatial dimensions (x, y, z) but also along a time axis, allowing the viewer to traverse through different temporal states. This dimensional expansion resolves the overlay problem by distributing objects across multiple time layers, making previously obscured objects visible at different temporal positions.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the unified 3D object space into multiple temporal segments or slices along the time axis. Each temporal slice represents a specific moment or state, and objects are distributed across these segments based on their temporal characteristics. This segmentation allows the viewer to focus on specific temporal segments where objects of interest are visible, reducing the obscuration effect from objects in other temporal segments.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If multiple anatomical and medical objects are displayed in the graphical display, then comprehensive information is provided, but objects overlay and obscure each other reducing diagnostic quality

Engineering Contradiction:
Improvecompleteness of informationVSAvoiddiagnostic quality
Core Design Contradiction:
Loss of informationVSReliability

Solution Approach 1:

By adding the time dimension to the display space, the patent transforms the 3D spatial overlay problem into a 4D separation problem. Objects that overlap in spatial dimensions can be separated along the time axis, allowing all objects to be displayed simultaneously without mutual obscuration. The viewer can navigate through temporal dimensions to access complete information while maintaining diagnostic quality through temporal separation of overlapping structures.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The time axis acts as an intermediary dimension that mediates between the need to display multiple objects comprehensively and the need to maintain their individual visibility. By introducing this intermediate temporal dimension, the system enables simultaneous display of multiple anatomical and medical objects while preventing their mutual obscuration through temporal distribution.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A graphical display is adjusted. A dataset having a map and/or a model of a plurality of anatomical and/or medical objects of an object under examination is acquired. A graphical display of the dataset is visualized by a display. Based on a capturing signal, at least one of the plurality of anatomical and/or medical objects being viewed by a viewer of the graphical display is identified. The capturing signal is provided by a capturing unit embodied to capture a partial area of the graphical display currently being viewed by a viewer and to provide the capturing signal in dependence on the captured partial area. The graphical display of the at least one identified object is adjusted by adjusting a display parameter of the graphical display.
