Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If visual analysis methods are used for pancreatic cyst classification, then the process is simple and easy to operate, but the measurement precision and classification accuracy are insufficient
Solution Approach 1:
The patent introduces an intermediary system consisting of a neural network model and image processing algorithms that act as a mediator between the CT images and the final classification. This intermediary automatically extracts morphological features and performs classification, resolving the contradiction by providing high measurement precision through automated analysis while managing system complexity through modular software architecture.
Solution Approach 2:
The patent replaces the mechanical/manual visual analysis system with an automated computational system using neural networks and image processing algorithms. This substitution transforms the classification process from manual observation to automated digital analysis, achieving superior measurement precision while the software-based system maintains operational simplicity through automated workflows.
2Measurement precision
If advanced image processing techniques are implemented, then the measurement precision improves, but the ease of operation decreases
Solution Approach 1:
The patent implements a self-service system where the image processing algorithms and neural network automatically perform feature extraction, segmentation, and classification without requiring manual intervention. The system serves itself by autonomously processing CT images, calculating morphological parameters, and generating classifications, thereby achieving high localization precision while maintaining ease of operation through automated workflows.
Solution Approach 2:
The patent performs preliminary actions by pre-training the neural network model with labeled data and pre-programming the image processing algorithms to automatically extract relevant features. This preliminary preparation enables the system to achieve high measurement precision during actual operation without requiring complex manual configuration or intervention, thus maintaining operational simplicity.
3Productivity
If manual classification methods are used, then the device complexity is low, but the productivity and efficiency are reduced
Solution Approach 1:
The patent implements continuous automated processing where the neural network and image processing algorithms continuously analyze CT images without interruption. The system processes multiple images and cysts in sequence, maintaining continuous useful action that significantly improves productivity compared to manual classification. The automated workflow eliminates idle time between analyses while the modular software architecture manages system complexity effectively.
Solution Approach 2:
The patent changes the operational parameters from manual assessment to automated computational analysis by adjusting the processing mode to use neural networks and algorithmic feature extraction. This parameter change enables high-speed processing of multiple images and cysts, dramatically improving classification efficiency while the systematic approach to parameter management keeps the processing system complexity controllable.

AI summary
A method and computer program product for the automatic classification of pancreatic cysts using CT images are proposed. The method comprises accessing a set of CT images of a patient; performing a filtering operation on the set of CT images, and defining a ROI within the filtered set of CT images; performing a segmentation operation of the defined ROI using a neural network, obtaining a segmented image representing values of a first value for the pixels occupied by a pancreatic cyst and values of at least a second value for the pixels not occupied by a pancreatic cyst; performing a morphological analysis of the pancreatic cyst by means of using an image processing algorithm that processes the pixels with the first value; and classifying the pancreatic cyst based on the morphological analysis and demographic data of the patient, the demographic data including the gender and age of the patient.
