7T MRI Facility
A 7T MRI has the ability of creating images with higher contrast, better resolution, and in shorter scan times when compared to a 3T device. Greater image quality enables the study of neuronal function at the submillimeter scale and ultra-high resolution fMRI in both animal models and human subjects.
The 7T MRI will be part of the Toronto Western Hospital’s Krembil Neuroscience Centre, a world leader in neurology, and completes the localized repertoire neuroimaging modalities to enable seamless study of subjects.
Cyclotron and Radiochemistry Laboratory
The Cyclotron and Radiochemistry Laboratory was first envisioned by the University Health Network’s Regenerative Medicine (REMEDI) Project as a means to obtain their objectives of (i) LABELLING, (ii) IMAGING, (iii) VISUALIZATION, and (iv) GUIDED DELIVERY of cell, gene and protein therapy. By having the on-site ability to produce customizable radiotracers, the physical constraints of short-lived radioisotopes and inaccessibility of these radioisotopes is eliminated, and the functional imaging capabilities of PET can fully exploited. The Cyclotron and Radiochemistry Lab will be built in the Clinical Services Building at the Toronto General Hospital, and will be a local resource for novel radioisotopes. It will also provide full proteomics support. The facility will not only fulfill the objectives of the REMEDI project but will be a resource for all biomedical research requiring such agents.
The University Health Network is operating its PETtrace 880 cyclotron, pictured above during maintenance, to accelerate particles and produce radioisotopes for nuclear imaging techniques. The radioisotopes are incorporated into various positron-emitting radiopharmaceuticals that are administered for PET/CT or PET/MRI imaging applications used for various cardiology, neurology, and oncology applications.

University Health Network’s cyclotron creates new era in production of medical isotopes
Starting with a blank canvas the construction of the new cyclotron/radiopharmacy facility has been a huge project and it is now nearing completion. We are right on target to be producing radioisotopes for clinical trials by the end of 2013. The cyclotron was delivered in September 2012 and the hot cells arrived in December 2012. They are awaiting installation following completion of the facility. It is anticipated that commissioning of the entire facility will begin in April.

The Magnetoencephalography (MEG) Facility will give neuroscientists and neurosurgeons the opportunity to non-invasively measure the magnetic fields generated by small intracellular electrical currents in neurons. It provides direct information about the dynamics of spontaneous and evoked neural activity and the location of their sources, thus enabling the identification of temporal profiles of cortical activity within millimeter resolution. MEG is highly complementary to MRI as it provides vital information of ‘when’ brain activity occurs while MRI supplies information about ‘where’ the activity occurs and the structure and anatomical connections of the brain. Located at the Toronto Western Hospital’s Krembil Neuroscience Centre, the MEG facility is expected to be operational in early 2014.
OpenLab at UHN, located at Toronto General Hospital, is a multi-disciplinary service design and innovation centre dedicated to developing solutions to complex problems that improve both the process and experience of care.

The PET/MR Facility features a whole-body PET camera inside a high-field 3T MRI system, located in the basement of Toronto General Hospital. Whole-body PET/MR will enable the study of metabolism and pathophysiology at the molecular level with simultaneous spatial localization of metabolites, taking advantage of MR imaging’s superior soft-tissue contrast capabilities.
The Magnetic Resonance guided Radiation Therapy (MRgRT) suite consists of a full strength (1.5 T) open bore MR imaging device on rails that will move between a linear accelerator and a High Dose Rate (HDR) brachytherapy suite. MR imaging can be achieved at the time of intervention with minimum disruption to the patient and interventional team. In addition, the MRgRT suite will enable the development of small robotic devices and intraoperative human interfaces for directing the intervention within the MR. This unique suite represents a major infrastructure enhancement as it will overcome current limitations in contrast performance of present cone-beam CT systems which are a limiting factor in targeting precision. MR-guided localization, motion assessment, targeting and monitoring of disease and normal structures can be completed at an unprecedented level of precision and accuracy. The technological advancements that will be achieved in this suite–when developed in concert with clinician scientists–promise to advance the practice of surgery and radiation therapies.
We have reached several major milestones this year!
Our most recent advancements in the MRgRT facility include:
Facility construction complete.
MR safety plan complete, including; safety training plan, safety charter and safety governance. A tremendous amount of preparation has been undertaken to ensure that safety is designed and built into the facility and the operating procedures. Both MRI safety concerns and radiation safety concerns need to be taken into consideration.

MR-Guided High Dose Rate (HDR) Brachytherapy
We officially completed construction of the HDR Brachytherapy Suite (below) on February 6, 2013. The HDR afterloader (treatment machine) has been installed and commissioned and we are happy to report that the first HDR brachytherapy patient was treated in the MRgRT facility without MR-image guidance on June 9th, 2014.
MR-Guided External Beam (Linear Accelerator/Linac) Radiation Delivery
The external beam MRgRT Suite consists of:
- A Varian TrueBeam linear accelerator for radiation treatment;
- The MR on rails which moves in and out of the suite;
- A novel robotic couch that can move between the MRI and treatment unit.
We continue to explore solutions to address the new challenges stemming from the addition of MRI and its clinical integration into the radiation treatment workflow. We are currently working on various engineering and research questions while awaiting Health Canada approval for this novel equipment.
Challenges being addressed include:
- Motion accuracy and precision of the MR and linac systems (MRI, linac, and treatment couch) in order to ensure the most accurate patient treatment;
- linical use and long-term performance of the MR imaging coils in a radiotherapy environment;
- MR imaging optimization to ensure we receive the best possible images for patients undergoing treatment in the suite.
The future landscape of this technology will prove to be an exciting advancement to patient care. With the technology nearing readiness for patient treatment our focus will move towards building a strong clinical program while still furthering technological development.
Phase I of the MRgRT Suite is now complete!
Construction of the High Dose Rate (HDR) Brachytherapy Suite was officially completed on February 6, 2013. The HDR device has been installed and is now undergoing commissioning tests. The new suite will be ready to treat brachytherapy patients on March 8, 2013. Construction is still ongoing for Phase II of the MRgRT Suite. The magnet for the imager has been installed and the linear accelerator suite will be ready for testing in May. Real-time MRI during radiation therapy is one step closer to becoming a reality at UHN.
MRgRT Breaks Ground.
The hoarding is up! Construction of the Magnetic Resonance guided Radiation Therapy (MRgRT) suite has begun. This innovative suite, the first in the world, will merge the imaging capabilities of a MRI supplied by IMRIS with advanced radiation therapy devices from Varian and Nucletron; creating a unique environment to fast track the development and integration of guided therapeutic devices, techniques, and procedures.
