Customer Challenge
90% of testing is done in actual CT machine which reduces development speed
Scope
- Develop a simulator to replicate the functionalities of gantry of a CT machine.
- The simulator should be connected to imaging workstation & table without actual X-Ray generator & detector.
- The simulator should be used for development and testing the Imaging software modules and also for V&V of the full system
Solution
- Quest Global developed Hardware Gantry simulators by re-using the existing CT Controller boards and its peripherals.
- The system was powered without using actual CT Power distribution unit.
- The peripherals were deployed in the customized 18U rack and the external connectivity option was provided for table, scan control board and foot pedal switches.
Benefits
- Reduced the time of Software Development Lifecycle as 80% of testing done at workstation side
- Reduced the Risk of Intrusive Software Testing
- Simulators mimic most of the functionalities of Gantry and reduced the risk & dependency on Actual CT bay
- System testing required only for performance & image quality related testing
