Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radiology practice methods face challenges such as exposure to radiation, high costs, and limited practice experience due to the need for expensive and bulky actual radiation equipment, which limits the ability to provide comprehensive training for future medical professionals.
Innovation Solution
A virtual reality-based radiology practice apparatus equipped with a head-mounted display (HMD) and hand-mounted unit that allows practitioners to manipulate virtual radiography equipment in a simulated environment, receiving hand motion signals to operate virtual equipment and output specific results, enabling diverse equipment handling and patient interaction without radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If actual radiology equipment is used for practice, then hands-on practice experience is improved, but radiation exposure risk and cost increase
Solution Approach 1:
The patent creates a virtual copy of actual radiology equipment and practice environments. The system uses computer-generated 3D models of radiology rooms, equipment, and patients, allowing practitioners to perform hands-on operations on virtual replicas without exposure to real radiation. This copying approach maintains operational training quality while eliminating harmful radiation exposure.
2Adaptability or versatility
If actual radiology equipment is used for practice, then realistic training scenarios are improved, but cost and space requirements increase
Solution Approach 1:
The virtual reality system serves multiple training functions within a single platform. It can simulate various radiology equipment types, different patient conditions, and multiple procedural scenarios without requiring separate physical equipment for each. The system provides universal training capabilities across diverse radiology contexts, reducing overall cost and space requirements compared to maintaining multiple actual equipment sets.
3Adaptability or versatility
If more radiology equipment is provided for practice, then training comprehensiveness is improved, but acquisition and maintenance cost increase
Solution Approach 1:
Instead of acquiring multiple physical radiology equipment units, the system creates virtual copies of various equipment types within the VR environment. Each virtual equipment model can be instantiated multiple times and configured for different training scenarios without additional hardware costs. This approach maintains training comprehensiveness while eliminating acquisition and maintenance expenses associated with physical equipment proliferation.
4Object-affected harmful factors
If virtual reality practice is used, then radiation exposure risk is reduced, but hands-on practice authenticity deteriorates
Solution Approach 1:
The system replaces physical mechanical interaction with virtual interaction through motion tracking technology. Hand-mounted sensors detect practitioner movements and translate them into corresponding actions within the virtual environment. This substitution maintains the tactile and procedural authenticity of hands-on practice while eliminating radiation exposure, as the virtual system responds to physical gestures without requiring actual contact with radiating equipment.
