Medical Imaging Gantry Collision Avoidance via Sensor Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical image diagnostic systems, particularly IVR-CT apparatuses, lack effective prevention and avoidance mechanisms for contact with other apparatuses and objects in the indoor space, leading to potential collisions during gantry movement.
Innovation Solution
The system incorporates cameras and sensors to detect interfering objects within the movement range of the gantry and IVR device, predicting potential collisions and outputting warnings or adjusting the movement path to avoid contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gantry moves in an indoor space without sufficient detection mechanisms, then the imaging operation is simple and fast, but the risk of collision with other apparatuses increases
Solution Approach 1:
The system performs preliminary detection of the movement range using cameras and sensors before the gantry moves. The control device calculates the movement range based on scanogram imaging data and detects interfering objects in advance, allowing the gantry to adjust its path proactively to avoid collisions rather than reacting after contact occurs.
Solution Approach 2:
The patent introduces cameras and sensors as intermediary detection devices that monitor the indoor space for interfering objects. These intermediaries provide the control device with information about the environment, enabling safe gantry movement without requiring direct physical sensors on the gantry itself.
2Reliability
If cameras and sensors are installed to detect interfering objects, then collision prevention capability is improved, but the system complexity and cost increase
Solution Approach 1:
The cameras and sensors are integrated into the existing medical image diagnostic system, serving dual purposes: they function as detection devices for collision avoidance and also contribute to the overall imaging and monitoring capabilities of the system. This multi-functionality reduces the need for entirely separate detection systems.
Solution Approach 2:
The control device utilizes existing imaging data from scanogram imaging to calculate the movement range and identify potential interfering objects. The system serves itself by leveraging its own imaging capabilities for safety detection, reducing the need for entirely external detection systems.
3Measurement precision
If the movement range is calculated based on scanogram imaging, then the positioning accuracy is improved, but the imaging time and processing complexity increase
Solution Approach 1:
The system performs scanogram imaging only for the specific purpose of calculating the movement range, rather than performing full diagnostic imaging. This partial action provides sufficient information for safety calculations without the time cost of complete imaging procedures, allowing quick positioning for collision avoidance.

AI summary
A medical image diagnostic system of an embodiment includes a medical image diagnostic apparatus and processing circuitry. The medical image diagnostic apparatus moves on a floor and performs scanogram imaging or main scan imaging. The processing circuitry is configured to acquire a scan protocol to be executed in the medical image diagnostic apparatus, specify a movement range of the medical image diagnostic apparatus on the basis of the scan protocol, acquire information on an area including at least the movement range, and detect or predict presence or absence of an interfering object in the movement range on the basis of the information.
