NeuroLogica's OmniTom Elite with Photon Counting Detector CT system
Researchers at the University of Dundee in Scotland are embarking on a new research project with NeuroLogica Corp., a subsidiary of Samsung Electronics, to refine imaging practices and identify differences in patients’ tissue characteristics with photon-counting CT.

The technology is designed to decrease pixel size and improve spatial resolution by converting individual X-ray photons into electrical signals that are acquired at the same time with configurable energy thresholds.

This holds the potential to improve image quality and resolution as well as segmentation of bone, blood clots, plaque, hemorrhage and intracranial tumors, according to professor Iris Grunwald, who leads the University’s Tayside Innovation MedTech Ecosystem (TIME) Neuro team and is an executive member of SINAPSE – Scottish Imaging Network: A Platform for Scientific Excellence.

“By utilizing the state-of-the-art equipment alongside the University of Dundee’s unique research and clinical expertise, together we can work to modernize the future of patient care,” she said in a statement.

Grunwald oversaw the installation of the the OmniTom Elite with Photon Counting Detector CT system at Dundee and previously worked with NeuroLogica to improve pre-hospital imaging on mobile stroke unit ambulances.

She says that using the scanner will not just improve the ability to examine these characteristics but allow for them to be better studied at lower doses, fundamentally changing the use of injected contrast.

Additionally, the technology can visualize minute details in organ structures and provide more accurate material density measurements or quantification.

“Tay Cities investment attracted professor Grunwald to Dundee to develop novel training techniques enabling the setup of a thrombectomy stroke service for our region. This new partnership represents a quantum leap in healthcare, allowing us to stay at the forefront in imaging and research internationally, while also enhancing patient diagnostics,” said Helen-Donald Simpson, Manager of TIME.

NeuroLogica’s research and development team designed the OmniTom Elite with PCD in-house in Danvers, Massachusetts, in collaboration with Samsung.
