Solution Overview
Problem
Conventional CT fluoroscopy systems require a trial and error process for determining the insertion position of treatment devices, leading to inefficiencies in diagnosis and treatment, increased X-ray exposure, and prolonged treatment times.
Innovation Solution
A tomographic system that simultaneously obtains and displays images at multiple positions, computes and displays relative distances between them, allowing operators to efficiently determine the insertion position of treatment devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional CT fluoroscopy displays tomographic images successively in time series, then the operator can view the images, but the operator cannot determine the insertion position efficiently and must undergo trial and error process
Solution Approach 1:
The system performs preliminary computation of relative distances between multiple tomographic images before the operator needs to determine the insertion position. By pre-calculating and displaying the relative distance information along with the tomographic images, the operator can immediately identify the correct insertion position without needing to perform trial scans, thus resolving the contradiction between ease of operation and time loss.
2Reliability
If the operator performs trial and error process to determine insertion position, then the operator can find the correct position, but the X ray exposure dose increases and treatment time is prolonged
Solution Approach 1:
The system provides feedback information in the form of relative distance measurements between multiple tomographic images. This feedback allows the operator to immediately identify the correct insertion position by comparing the displayed relative distances with the anatomical structures in the images, eliminating the need for multiple trial scans and thereby reducing X ray exposure dose while maintaining high accuracy in insertion position determination.
3Productivity
If multiple tomographic images are obtained simultaneously at different positions, then the relative distance information can be computed and displayed, but the device complexity increases
Solution Approach 1:
The tomographic system is designed to perform multiple functions: it simultaneously obtains tomographic images at different positions, computes relative distances between these images, and displays both the images and distance information. By integrating these multiple functions into a single system, the patent achieves high productivity in diagnosis and examination without requiring separate devices for each function, thus managing device complexity while improving efficiency.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces the number of trial scans, minimizes X-ray exposure, and shortens treatment times by enabling precise determination of the insertion position in a single or two scans, with the potential to reduce X-ray irradiation time by up to a third.
Implementation Method 1
a scanning means for simultaneously obtaining tomographic images at plural tomographic positions in the axial direction of a body of a subject
Data Source
AI summary
A tomographic system displays plural tomographic images, a relative distance between the tomographic images, whereby the operator can see the displayed data of the relative distances between tomographic images and the length of the treatment device instantaneously, and can therefore determine the insert position or the treatment device for the subject efficiently.
