Compact PET Camera Developed in Thunder Bay May Go to Market Soon


Radialis Medical has produced a high resolution camera for imaging body organs.

THUNDER BAY – A new diagnostic imaging device based on technology developed in Thunder Bay may hit the international market in the near future.

Radialis Medical, a joint venture between Thunder Bay Regional Health Research Institute and Lakehead University, is seeking regulatory approval to distribute a PET (positron emission tomography) camera that targets individual organs.

“Compared to whole-body PET scans, an organ-targeted PET camera positions the detectors in close proximity to the organ of interest for a better image of a smaller field of view,” said Michael Waterston, CEO of Radialis Medical.

Radialis is now asking the US Food and Drug Administration for permission to sell its compact PET system.

He says the device would be an ideal addition to clinics with whole-body PET systems because of its improved sensitivity, resolution and flexibility that allow precision imaging of multiple organs with as little as 1 / 10th of the body. normal dose of radiotracer.

PET scans require radioactive tracers to detect abnormalities inside the body.

The system developed by Radialis uses patented light sharing technology to locate the radiation emission.

Its underlying technology was developed in Dr. Alla Reznik’s research lab at Lakehead University and the TB Regional Research Institute.

Reznik said that emerging radiotracers under development for PET imaging “make it possible to visualize specific disease processes and facilitate precision medicine.”

She said the Radialis camera is the first organ-targeted PET system focused on low-dose imaging of several diseases.

The device is currently under investigation at the University Health Network-Prince Margaret Cancer Center in Toronto for imaging suspicious breast abnormalities.

Dr Andrew Dean, Vice President / Research and Innovation at Lakehead, called the FDA request “a big step as Radialis prepares to develop its new cancer detection imaging equipment.”

Dean added that setting up manufacturing facilities in Thunder Bay to produce the device is equally exciting.

Radialis already manufactures its research systems there.

Waterston told TBNewswatch that he plans to increase production as regulatory approvals are received.

The hiring of additional staff, he said, will be based on the volume of orders received.
