ABSTRACT
This paper suggests how to ensure the production quality when the common X-ray machine is refitted to DR system,and describes that a suitable X-ray machine and an aptitude company are necessary to refit DR system.It also introduces some methods on how to refit,inspect and practise in order to ensure the refitted DR system a reliable quality,stable performance and clear image.
ABSTRACT
Magnetic Navigation assisted cardiovascular intervention is the most advanced and innovative technique in the world.Under the guidance of magnet and pushed by a motor-driver,the catheter could reach the target automatically within the shortest time.Magnetic navigation system could help the cardiologists to decrease the operation time with a higher successful rate,and be exempt from the X-ray radiation using computerized remote-control technique.The paper has introduced the principle,advantage and clinical application of magnetic navigation system in detail.
ABSTRACT
Over exposal dose often occurs in CR system because of reduction of performance, contamination, dilapidation and aging of IP board, etc. The exposal dose tester is used to test and calibrate CR system. In this way, the problem of incorrect exposal dose of CR system is solved and image in high definition is obtained under proper exposal dose.
ABSTRACT
The effectiveness and safety of medical equipment are probed. The safety of cardiovascular interventional equipment is mainly discussed. Not only the effectiveness but also the safety must be focused. Countermeasures for safety problems are raised.
