Solution Overview
Problem
The existing techniques for processing medical images obtained by multi-energy CT scans are inefficient in calculating and displaying analysis values unique to these scans, as they require starting analysis applications, leading to increased processing time and reduced operability.
Innovation Solution
A processing apparatus and method that reconstructs a first image based on multi-energy CT scan data and displays side-by-side numerical values for the specified region of interest (ROI) on the first image, along with corresponding values from a second image, without requiring the reinitialization of analysis software, utilizing a system comprising a memory, display, input interface, and processing circuitry integrated with a multi-energy X-ray CT apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an analysis application is started and executed to calculate analysis values for multi-energy CT scan, then the analysis values can be displayed on the display, but it takes time due to the start of the analysis application
Solution Approach 1:
The processing apparatus performs image reconstruction and calculation of analysis values (such as CT values, area, and material discrimination) in advance during the CT scan acquisition process. By preparing the first image and calculating analysis values before the display is needed, the system eliminates the time delay that would otherwise occur when starting and executing analysis applications after the scan is complete.
Solution Approach 2:
The patent combines the image reconstruction process with the analysis value calculation process into a single integrated workflow. The processing apparatus reconstructs the first image and calculates analysis values simultaneously using the same scan data, rather than performing these as separate sequential operations. This merging of processes eliminates the need to start separate analysis applications and reduces overall processing time.
2Ease of operation
If a first image is reconstructed based on scan data, then the first image can be displayed on the display, but additional processing is needed to display analysis values from a second image
Solution Approach 1:
The processing apparatus is designed to perform multiple functions using a single integrated system. It can reconstruct the first image from scan data, generate a second image for material discrimination, calculate analysis values for both images, and display all results on the display. This multi-functional approach eliminates the need for separate analysis applications and reduces system complexity despite the multiple processing steps.
Solution Approach 2:
The processing apparatus acts as an intermediary that manages the complex workflow between scan data acquisition, image reconstruction, analysis value calculation, and display. It coordinates the processing of both the first image and second image, ensuring that analysis values are calculated and displayed in an integrated manner rather than requiring multiple separate applications to communicate with each other.
3Loss of information
If analysis values are calculated and displayed for a region of interest, then diagnostic information is provided, but the processing time increases due to multiple calculations
Solution Approach 1:
The system calculates analysis values for the region of interest during the image reconstruction process itself, rather than performing these calculations separately after the images are generated. By preparing diagnostic information in advance as part of the standard processing workflow, the system provides complete diagnostic data without adding significant processing time.
Solution Approach 2:
The processing apparatus continuously performs image reconstruction and analysis value calculation as an ongoing process rather than as discrete separate steps. The useful action of processing scan data into diagnostic information continues without interruption, combining multiple calculations into a single continuous workflow that delivers comprehensive diagnostic information efficiently.

AI summary
A processing apparatus for a medical image that is obtained by a multi-energy CT scan according to an embodiment includes processing circuitry. The processing circuitry reconstructs a first image based on scan data that is obtained by a multi-energy CT scan. The processing circuitry causes a display to display side by side, with respect to an area of interest that is specified on the first image, a first numerical value obtained based on the first image and a second numerical value obtained based on a second image that is different from the first image and that is obtained based on the scan data.
