Siemens MR Training

Siemens MR 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, like MR_TECH_003.

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

Some of them being magnets working at very high cryogen pressures like 15 psi, it is very likely to loose considerable amounts of liquid helium during cooling system problems. This course will teach all you need to know about Siemens Magnets and how to keep them healthy.

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

You will learn about the Refrigerator Subsystem troubleshooting, coldhead/adsorber replacement, MSUP secrets and many more useful topics about the Siemens Magnets.

This course covers the following MR Magnets;

- Oxford OR35, OR70, OR105 used by Siemens
