Research capabilities

 The HFMRI system is available for use by researches from universities, industry or other institutions. It has the potential to be utilised in various disciplines such as biomedical sciences, pharmaceuticals, food and agriculture, materials sciences and many others. We have been working with a number of research groups to develop protocols for various studies ranging from structural imaging in food to cardiac function studies.

With the availability of facilities such as the anaesthetic monitoring set up and the various coil configurations, the system is already being used in a broad range of applications. These capabilities are constantly expanding owing to the continual development of the infrastructure and expertise in the facility.     

MRI equipment

The MRI system comprises a Varian 4.7T magnet controlled by a UnityInova spectrometer.     


Depending on the size of the sample of interest, we have two configurations. The larger diameter coil (inner diameter 210mm) has a gradient strength of 20G/cm (200mT/m). It is designed to be used in conjunction with a 140mm ID RF probe.


The second configuration uses a stronger 100G/cm (1T/m) gradient system but of a smaller size (65mm ID). A 40mm ID RF probe, based on Varian's millipedeā„¢ design is used in this configuration.


A third volume coil (72mm ID) has been ordered for this facility and is expected to be available for use in the near future. A series of 2cm ID surface coils designed for imaging and spectroscopy of other MRI detectable nuclei is also available for use with both gradient coil configurations. We have the hardware available for the detection of various nuclei including 1H, 2H, 15N, 19F, 23Na and 31P.     

Anaesthetic and monitoring

Equipment is available for anaesthetics and the monitoring of vital signs inside the magnet bore. An anaesthetic unit is situated outside of the magnet room, with long tubing used to deliver anaesthetic agents. Temperature, ECG and respiration rate are monitored by equipment from SA Instruments Inc and can be observed on a computer situated outside of the magnet room.     

Sequence development


CAMRI has the facility to develop pulse sequences for the system to meet the varied requirements of researchers. We have a strong relationship with Varian Inc in which we have access to additional pulse sequences. Varian can also provide us with assistance in the development of highly specialised sequences.
