GE MR Training

GE Magnets

This technical training course is specially designed for Field Service Engineers working with Independent Service Organizations. This highly advanced course is not offered to Biomedical Technicians/Engineers or other technical staff at the hospitals since a lighter version of first line Magnet service is covered in our equipment specific MR courses, MR_TECH_001 and MR_TECH_002.

This course aims to bring the student at a technical level so that he can perform periodic maintenance, status checks, troubleshooting on GE Magnets with confidence. By the end of the training, student will gain the capability of troubleshooting on the GE MR Magnets.

Every year, thousands of litters of liquid helium is lost just because the magnet is not looked after in the right manner. This course will teach all you need to know about GE 1.5T Magnets.

During the course period, you will join hands on practical sessions and find chance to play(!) with the actual GE LCC MR magnet itself. At these sessions, you will gain confidence and in depth knowledge about the equipment.

You will learn about the Cryogen Subsystem troubleshooting, coldhead/adsorber replacement, gradient coil replacement, Magnet Monitor secrets and many more useful topics about the GE LCC Magnet.

This course covers the following MR Magnets;

- GE 1.5T and 1.0T Active Shield LCC Magnet and Cryogens Subsystem
