Solution Overview

Problem

Conventional imaging systems are limited to a single source and single detector, restricting the imaged volume to the size of the source and detector, necessitating larger components for larger objects.

Innovation Solution

A multiple source imaging system with a navigation system to track the pose of instruments, using a plurality of spaced-apart sources emitting signals like x-rays, detected by a detector, allowing image data acquisition from various positions and orientations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of stationary object

If a single source and single detector are used, then the device complexity is low, but the imaged volume is limited to the size of the source and detector

Engineering Contradiction:
Improveimaged volumeVSAvoiddevice complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The imaging system is segmented into multiple independent source-detector pairs, where each pair can image a specific region. By dividing the imaging task across multiple segments (sources and detectors), the system achieves a larger total imaged volume without requiring each individual component to be excessively large.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Multiple source-detector pairs are merged into a single integrated imaging system. The combined system achieves a larger effective imaged volume by merging the capabilities of multiple smaller source-detector units, allowing simultaneous or sequential imaging of larger objects.

Inventive Principle:
Principle #5Merging (Combining)

2Volume of stationary object

If a larger source and detector are used to image larger objects, then the imaged volume increases, but the device complexity and size requirements increase

Engineering Contradiction:
Improveimaged volumeVSAvoidsource and detector size
Core Design Contradiction:
Volume of stationary objectVSArea of stationary object

Solution Approach 1:

Instead of using one large source and detector, the system uses multiple smaller sources and detectors arranged in arrays. Each source-detector pair images a portion of the object, and the combined data reconstructs the full large-volume image, avoiding the need for oversized individual components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a single source-detector configuration to a multi-source multi-detector array configuration, adding spatial dimensions to the imaging capability. This dimensional expansion allows the system to cover larger volumes by distributing sources and detectors across multiple positions rather than relying on increased size of individual components.

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

3Volume of stationary object

If multiple sources and detectors are used to image larger volumes, then the imaged volume increases, but the device complexity increases

Engineering Contradiction:
Improveimaged volumeVSAvoiddevice complexity
Core Design Contradiction:
Volume of stationary objectVSDevice complexity

Solution Approach 1:

The multiple sources and detectors are designed with universal functionality, where each source-detector pair can operate independently or in coordination with others. This multi-functionality allows the system to adapt to different imaging scenarios and object sizes, reducing the complexity burden by using standardized, interchangeable components rather than specialized equipment for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

Enables imaging of larger volumes by spacing sources apart and moving them relative to the subject, enhancing the imaged volume beyond the physical limits of a single source-detector setup.

Implementation Method 1

The plurality of sources may be individually powered to emit a signal, such as x-rays, from each of the individual sources. The x-rays from each of the sources may be detected by a detector at a selected time.
