Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 3D medical scans are transmitted over the Internet using conventional methods, then advanced visualization is achieved, but bandwidth consumption increases and latency increases
Solution Approach 1:
The system segments the 3D medical scan data into multiple 2D planar cross-sections that can be transmitted separately over the Internet. Instead of transmitting the entire 3D volume at once, the data is divided into manageable 2D slices that consume less bandwidth, and these segments are reassembled at the receiving end to reconstruct the 3D visualization.
Solution Approach 2:
The system introduces a server as an intermediary that processes and manages the transmission of medical scan data. The server receives 3D volume datasets, converts them into 2D planar cross-sections, and manages their transmission to client devices. This intermediary approach allows for efficient data handling and reduces the direct bandwidth burden between the original data source and the end user.
2Ease of operation
If 3D virtual views are generated dynamically on user's computer, then interactivity is improved, but processing power requirements increase and data security risks increase
Solution Approach 1:
The system extracts and separates the complex processing functions from the user's computer and relocates them to a remote server. The server performs the computationally intensive tasks of generating 3D virtual views from 2D scans, while the user's computer only needs to handle display and basic interaction. This extraction reduces the processing power requirements at the client end while maintaining interactivity.
Solution Approach 2:
The system performs preliminary processing of medical scan data on the server before transmission to the user's computer. 3D virtual views are pre-generated from 2D scans and prepared in advance, allowing users to interact with already-processed data rather than requiring their local machines to perform complex real-time rendering. This preliminary action reduces both processing requirements and latency.
3Speed
If medical records are stored locally at facilities, then access speed is improved, but security and privacy management burden increases
Solution Approach 1:
The system merges the data storage and management functions into a centralized cloud-based infrastructure. Instead of each facility maintaining separate local storage systems with individual security protocols, all medical records are consolidated in a secure centralized repository. This merging reduces the administrative burden of managing multiple security systems while maintaining fast access through efficient data retrieval mechanisms.
Solution Approach 2:
The system implements automated security and access management features that reduce the need for manual administrative intervention. User authentication, data access permissions, and security protocols are handled automatically by the system infrastructure, eliminating the need for facilities to manually manage security configurations and reducing the administrative burden on IT staff.
Data Source
AI summary
A system for viewing at a client device a series of three-dimensional virtual views over the Internet of a volume visualization dataset contained on centralized databases employs a transmitter for securely sending volume visualization dataset from a remote location to the centralized database, more than one central data storage medium containing the volume visualization dataset, and a plurality of servers in communication with the centralized databases to create virtual views based on client requests. A resource manager load balances the servers, a security device controls communications between the client device and server and the resource manager and central storage medium. Physically secured sites house the components. A web application accepts at the remote location user requests for a virtual view of the volume visualization dataset, transmits the request to the servers, receives the resulting virtual view from the servers, and displays the resulting virtual view to the remote user.
