Solution Overview

Problem

Conventional X-ray diagnostic apparatuses require precise positioning of subjects, which can be burdensome for individuals with pain or physical disabilities, limiting their ability to maintain the necessary posture for effective imaging.

Innovation Solution

An X-ray diagnostic apparatus that includes an imaging unit with a processor to determine if examination protocols are executable based on geometric information from both the examination protocol and camera-captured images, allowing for adjustments to minimize physical burden on the subject by moving the X-ray tube and detector to maintain optimal positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If prescribed positioning is required for X-ray imaging, then imaging quality and diagnostic accuracy are improved, but physical burden on subjects increases

Engineering Contradiction:
Improveimaging qualityVSAvoidphysical burden
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The system dynamically adjusts the imaging apparatus positioning based on detected subject geometric information. Instead of requiring the subject to maintain a fixed prescribed posture, the X-ray tube and detector are moved to positions that accommodate the subject's actual posture, resolving the contradiction between maintaining imaging quality and reducing physical burden.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the geometric parameters (position and angle) of the imaging apparatus based on detected subject characteristics. By calculating optimal imaging parameters that work with the subject's actual posture rather than requiring prescribed positioning, the system maintains diagnostic accuracy while reducing physical burden on vulnerable subjects.

Inventive Principle:
Principle #35Parameter changes

2Stability of the object's composition

If prescribed positioning is enforced for all subjects, then examination protocol consistency is improved, but adaptability to individual subject conditions deteriorates

Engineering Contradiction:
Improveexamination protocol consistencyVSAvoidadaptability to subject conditions
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The system performs self-adjustment by automatically detecting subject geometric information and calculating appropriate imaging parameters. This self-service capability allows the apparatus to adapt to individual subject conditions while maintaining examination quality, eliminating the need for rigid prescribed positioning protocols.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback from geometric information detection to adjust imaging parameters. By continuously monitoring subject positioning and adjusting apparatus geometry accordingly, the system maintains protocol consistency adapted to individual subject needs, resolving the contradiction between standardization and adaptability.

Inventive Principle:
Principle #23Feedback

3Adaptability or versatility

If manual positioning adjustment is required for difficult-to-position subjects, then examination flexibility is improved, but examination time increases

Engineering Contradiction:
Improveexamination flexibilityVSAvoidexamination time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system replaces manual mechanical positioning adjustments with automated detection and calculation. By using geometric information detection and automated parameter calculation, the system achieves the same flexibility in accommodating difficult-to-position subjects without the time-consuming manual adjustment process.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
