Study Notes
Tube Lifespan and Design
- Working life of tubes used to date ranges from 10,000 to 40,000 hours.
- Conventional CT tubes typically have a lifespan of 1,000 hours.
- Engineering changes increased the mass of the tube, which led to design efforts focusing on reducing the mass.
- The goal of reducing mass was to better withstand increasing gantry rotational rates.
- Increasing gantry rotational rates are required by ever-faster scan times.
This quiz assesses your knowledge of CT scan tube technology, including their working life and engineering improvements. Questions may cover the extended lifespan of modern tubes and design efforts to reduce their mass.
