Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical imaging systems face challenges in reliably and reproducibly positioning patients for dental volumetric scans, often resulting in unnecessary exposure to radiation due to the selection of larger volumes to compensate for uncertain positioning.
Innovation Solution
A bite block device with integrated cameras and illumination components is used to capture images of the oral cavity, allowing for precise patient positioning and enabling the selection of a minimal volume for X-ray scans, including features like cameras and illumination components that project into the oral cavity to guide accurate image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a larger volume is selected for imaging to compensate for uncertain positioning, then patient positioning reliability is improved, but radiation exposure increases
Solution Approach 1:
The system performs preliminary optical imaging and 3D reconstruction of the patient's anatomy before the main X-ray scan. This preliminary action allows the operator to precisely identify the region of interest and plan the scan volume, ensuring that the subsequent X-ray scan covers only the necessary minimal volume rather than a larger safety margin, thus reducing radiation exposure while maintaining positioning reliability
Solution Approach 2:
The system provides real-time visual feedback through optical images and 3D reconstructions displayed to the operator during positioning. This feedback mechanism allows the operator to verify the positioning accuracy and adjust the scan volume selection accordingly, ensuring that the minimal necessary volume is imaged without excessive radiation exposure
2Device complexity
If conventional positioning methods are used without internal cavity reference, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent introduces an optical imaging system as an intermediary between the operator and the patient's anatomy. The optical camera captures images of the oral cavity, and the system generates 3D reconstructions that serve as a visual mediator, allowing the operator to precisely identify anatomical landmarks and plan the scan volume without adding significant mechanical complexity to the positioning apparatus
Solution Approach 2:
The system replaces complex mechanical positioning mechanisms with optical imaging and software-based 3D reconstruction. Instead of using mechanical guides or physical alignment tools, the operator uses visual information from optical images and 3D models to position the scan volume, substituting mechanical complexity with optical and computational methods
