Monash Biomedical Imaging operates Australia’s only research-dedicated Siemens Biograph mMR scanner, which is capable of simultaneous magnetic resonance (MR) and positron emission tomography (PET) imaging.
The MR-PET scanner allows for concurrent acquisition of morphology, function, and metabolism. Its key features include:
Sensitivity that is almost 40% better than PET-CT
Industry-leading MR image quality for off-centre imaging, fat saturation and spectroscopy
Improved clinical outcomes with high definition-PET, giving benchmark PET image quality using measured Point Spread Functions, producing images with improved uniformity, higher resolution and more contrast
32" BOLDScreen for stimuli presentation.
Two CCTV cameras mounted inside the scan room connected to two monitors in the control room for zoomed viewing of participants and wide angle coverage of the entire room at all times.
3 Tesla with 60cm bore diameter, short bore and high homogeneity
TrueForm magnet design, producing a cylindrically optimised homogeneity volume that results in better image quality by reducing unusable edges in the images, as well as better fat saturation for the whole area covered in the scan.
MR gradient system
Actively shielded whole-body gradient coil system
Extremely low eddy currents
Gradient coil length 159cm, optimised for gradient linearity
Excellent spatial and temporal resolution
Active shim via 3 linear channels with 20 coils
Combined with 5 additional non-linear second order channels with 32 coils for advanced high order shim
Maximum acoustic noise level is 118 dB(A)
Crystal material - LSO
Crystal elements per block - 64
Total detector blocks - 448
Total number of crystal elements - 28,672
Image planes - 127
PET offline reconstruction
Provides static and whole-body PET reconstruction capabilities outside the context of an acquisition, from saved PET raw data
The Biograph mMR Application Suites provides a complete range of optimised examinations for all regions. From simultaneous MR and PET to individual MR or PET exams, excellent head-to-toe imaging can be accomplished with the sequences and features included in the Application Suites:
