Solution Overview
Problem
The manual preparation and adaptation of patient-specific orthoses or prostheses are time-consuming, costly, and require extensive education and expertise, as they necessitate manual alignment and modification of anatomical data from patient scans, leading to inaccuracies and increased effort.
Innovation Solution
A computer-implemented method standardizes the position and orientation of anatomic structural data from patient scans by aligning it with template data using armature and registration algorithms, allowing for efficient and accurate adaptation for orthosis or prosthesis fitting, reducing the need for manual realignment and improving measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual preparation and adaptation of patient-specific orthoses or prostheses is performed, then individual fitting accuracy is improved, but time consumption and cost increase
Solution Approach 1:
The patent applies preliminary action by pre-defining template structural data with armature and standardized positions before actual patient data processing. The template includes pre-configured mechanical deformation models and registration algorithms that are prepared in advance, allowing rapid alignment and adaptation of patient-specific anatomical data without manual intervention during the fitting process.
Solution Approach 2:
The patent replaces manual mechanical alignment and adaptation processes with automated computer-implemented methods. Registration algorithms automatically align patient anatomical data with template structural data, and software systems perform measurements and generate fitting plans, substituting the manual mechanical operations of certified prosthetists with automated computational processes.
2Manufacturing precision
If manual alignment and modification of anatomical data is performed, then individualized fitting is improved, but expertise requirements and training costs increase
Solution Approach 1:
The patent enables self-service by designing an automated system that performs alignment, registration, and measurement tasks without requiring expert manual intervention. The computer-implemented method automatically processes patient anatomical data, aligns it with templates using registration algorithms, and generates fitting plans, making the process accessible without extensive professional training while maintaining high precision.
Solution Approach 2:
The patent replaces the complex manual expertise-based system with automated computational algorithms. Registration algorithms and software-based measurement tools substitute the knowledge and skills of certified prosthetists, eliminating the need for extensive education and background knowledge while achieving comparable or superior individualized fitting results.
3Productivity
If standardized template data with armature is used, then processing efficiency is improved, but initial system complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring template structural data with armature, standardized positions, and registration algorithms before actual use. These templates are prepared in advance with all necessary geometric models, coordinate systems, and transformation parameters, enabling rapid processing of patient data without requiring complex real-time computations during the fitting process.

AI summary
The invention relates to a computer-implemented method for providing a standardized position for anatomic structural data (ASD) of a patient scan, in particular as a basis for individually fitting an orthosis or prosthesis to a first patient. The method comprises the steps of receiving anatomic structural data (ASD) of a body part of the first patient, receiving and/or selecting template structural data (TSD) corresponding to the body part and adapting the orientation and/or the pose of the anatomic structural data (ASD) using the armature of the template structural data (TSD). Further, the invention refers to a computer-implemented method for providing standardized measurement on anatomic structural data (ASD) of a patient scan, a data processing system and a computer-readable medium.
