Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dynamic effects such as object motion and environmental changes during medical imaging degrade image quality, leading to artefacts that can hinder clinical diagnosis and increase healthcare costs, with existing correction methods being limited in their effectiveness and requiring significant changes to imaging software or hardware.
Innovation Solution
A Dynamic Correction Module (DCM) is integrated with medical imaging apparatus to automatically and dynamically optimize image acquisition parameters and commands in real-time, using dynamic change data from various sources to adapt imaging procedures without altering the existing imaging control or hardware systems, thereby mitigating artefacts caused by motion and other dynamic effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If prospective correction methods are used to adapt imaging parameters dynamically during acquisition, then image quality is improved, but device complexity increases due to considerable changes in control software or hardware
Solution Approach 1:
A camera system serves as an intermediary device to capture object position information and transmit it to the imaging control system. This intermediary approach allows dynamic correction without requiring complex modifications to the core imaging control software or hardware, thereby improving image quality while limiting device complexity changes.
Solution Approach 2:
The system implements a feedback loop where the camera system continuously monitors object position, sends position information to the imaging control system, which then adjusts imaging parameters in real-time. This feedback mechanism enables dynamic adaptation to object motion while maintaining a relatively simple system architecture.
2Device complexity
If retrospective correction techniques are used to correct data after acquisition, then device complexity is minimized, but image quality improvement is limited since some artefacts are not correctable a posteriori
Solution Approach 1:
The system performs preliminary action by capturing object position information during the imaging acquisition process using the camera system. This allows the imaging control system to adjust imaging parameters in real-time based on actual object position, preventing artefact formation rather than attempting to correct them after acquisition. This approach improves image quality without requiring complex retrospective correction algorithms.
3Manufacturing precision
If real-time adaptation of imaging parameters is implemented, then artefacts from dynamic effects are reduced, but loss of time occurs due to additional processing and communication overhead
Solution Approach 1:
The system implements efficient real-time processing by rapidly capturing object position information with the camera system and quickly transmitting this data to the imaging control system. The imaging control system then swiftly adjusts imaging parameters based on the position information, rushing through the correction process to minimize additional processing time while still achieving effective artefact reduction.

AI summary
The present invention discloses essentially a method for automatically and dynamically optimizing image acquisition parameters/commands of an imaging procedure performed by a medical imaging apparatus in order to mitigate or cancel dynamic effects perturbing the image acquisition process of an object to be imaged by said medical imaging apparatus, the method comprising: a. connecting a Dynamic Correction Module (hereafter DCM) to the medical imaging apparatus; b. automatically acquiring by the DCM image acquisition parameters/commands and data about dynamic changes or effects; c. automatically determining in real time, by means of the DCM, at least one new image acquisition parameter/command from the image acquisition parameters/commands defined in the imaging control system and the dynamic change data, while the image acquisition parameter/command defined in the imaging control system remains unchanged; d. automatically providing, by means of the DCM, the new image acquisition parameter/command to the hardware control system.
