Radiographic Imaging Support System Using Optical Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing radiographic imaging support systems face challenges in positioning patients for radiographic imaging, particularly for first-time imaging subjects and when the size of the target position does not match the actual patient, leading to inaccuracies in positioning.
Innovation Solution
A radiographic imaging support system that uses a hardware processor to acquire optical image information, generate target position information using a learned classifier, and output this information, which includes size data, to assist in accurately positioning the radiographing site relative to the radiographic imaging apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a virtual scene of a virtual patient is used to generate target position information, then positioning support can be provided for any patient, but the target position size may not fit the actual patient's size, causing gaps or coverage issues
Solution Approach 1:
The patent applies local quality by extracting specific anatomical landmarks and local geometric features from the optical image of the actual patient's radiographing site, rather than using a generic virtual patient model. This allows the target position information to be adapted to the local characteristics and size of the actual patient's body part, ensuring both availability for any patient and accuracy in positioning.
Solution Approach 2:
The patent changes parameters by dynamically adjusting the target position information based on the actual size and geometric parameters extracted from the optical image of the patient's radiographing site. The system modifies the target position parameters to match the specific dimensions of the patient's body part, resolving the contradiction between universal applicability and size-specific accuracy.
2Reliability
If a radiograph of the same patient radiographed in the past is required for positioning support, then positioning can be supported for returning patients, but the system cannot be utilized for first-time imaging patients
Solution Approach 1:
The patent applies self-service by enabling the system to generate target position information directly from the optical image of the current patient's radiographing site without requiring historical radiographs. The system uses real-time optical imaging and automatic feature extraction to provide positioning support for any patient, including first-time imaging patients, thereby eliminating the limitation of requiring past radiographs while maintaining reliable positioning support.
3Ease of operation
If the target position size is larger than the actual patient, then the target position cannot be easily positioned, but if the target position is smaller, then it may be covered by the patient
Solution Approach 1:
The patent applies dynamics by making the target position information adaptive and dynamic based on the actual patient's body part dimensions extracted from the optical image. The system dynamically adjusts the target position size and location to optimize both visibility for easy positioning and precision for accurate imaging, resolving the contradiction between ease of operation and positioning accuracy.

AI summary
A radiographic imaging support system that supports positioning of a radiographing site of a subject with respect to a radiographic imaging apparatus, includes a hardware processor that acquires image information based on an optical image obtained by capturing an image of the radiographing site with an optical camera, generates first target position information regarding a target position of the radiographing site, and outputs the generated first target position information. The first target position information includes information corresponding to a size of the radiographing site.
