Solution Overview
Problem
Current PET systems face challenges in data transmission efficiency and real-time data processing, particularly when requiring higher resolution images, due to complex connections and low-speed buses, which hinder the integration of more collecting modules and meet the demand for real-time data transmission.
Innovation Solution
A PET system with a serial non-closed-loop connection of collecting modules using a high-speed serial bus, where data packets are superposed and transmitted in a unidirectional manner, eliminating the need for a data gathering module and coincidence processing module, and allowing the host computer to determine coincidence events based on the superposed data structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If more collecting modules are integrated to improve image resolution, then measurement precision is improved, but device complexity increases due to complex connections and low-speed buses
Solution Approach 1:
The system segments the data transmission function by assigning each collecting module an independent address identifier, allowing modular integration without increasing connection complexity. Each module operates independently with its own identification, enabling scalable integration of more modules for higher resolution while maintaining manageable system complexity.
Solution Approach 2:
The patent introduces a new dimension of address-based identification rather than physical connection topology. By using address identifiers in the data packets, the system transitions from complexity managed through physical wiring arrangements to complexity managed through logical addressing, enabling easier integration of additional modules.
2Measurement precision
If more collecting modules are integrated to improve image resolution, then measurement precision is improved, but productivity decreases due to low-speed data transmission
Solution Approach 1:
The system changes the parameter of data packet structure by incorporating address identifiers and using unidirectional transmission protocols. This parameter change optimizes the data transmission efficiency, allowing faster processing and transmission of data from multiple collecting modules, thereby improving productivity while maintaining high resolution capability.
3Measurement precision
If complex connection structures are used to integrate more collecting modules, then measurement precision is improved, but ease of operation decreases
Solution Approach 1:
Each collecting module is segmented with its own address identifier, allowing independent configuration and operation. This segmentation simplifies system setup and operation, as each module can be individually addressed and configured without requiring complex inter-module wiring arrangements, thereby improving ease of operation while enabling high resolution through multiple modules.
