Subtle Medical provides a suite of deep learning software solutions that enhance images during the acquisition phase of the radiology workflow.
SubtlePET™ is an AI-powered software that denoises images acquired in up to 1/4th the original scan time.
SubtleMR™ is an AI-powered software solution used to enhance the quality of accelerated MRI protocols by increasing image sharpness and denoising.

Benefits

SubtlePET: Better patient experience

SubtlePET improves the quality of accelerated scan protocols. With accelerated scan times, sites are able to get their patients in and out of the scanner faster, particularly beneficial for children under sedation and those who have a hard time holding still for long periods of time. Less time in the scanner reduces patient discomfort, anxiety, and even pain.

SubtlePET: Improved image quality

SubtlePET applies denoising to improve the image quality from scans conducted in 1/4th the original scan time, maintaining clinically diagnostic image quality equivalent to the ground truth image.

SubtlePET: Increased efficiency

SubtlePET improves the quality of accelerated scan protocols. With accelerated scan times, hospitals and imaging centers can scan more patients per day on their existing PET machines, which reduces wait times, increases PET capacity, and frees up time on the scanner for other applications like CT and cardiac PET.

SubtlePET: Cutting edge technology on a site’s existing machines

SubtlePET was developed from proprietary deep learning algorithms to enable centers to easily implement the newest imaging enhancement technology without purchasing new expensive PET scanners, extending the life of existing scanners.

SubtleMR: Improved quality

Applies two methods of image enhancement — denoising and increased sharpness— to improve image quality.

SubtleMR: Better patient experience

Improves the quality of suboptimal scans, avoiding the need for re-scans which can be a challenge for patients.

SubtleMR: Broad applicability

Works with brain, spine, and knee protocols and compatible with any brand or model of MRI scanner and field strength.

SubtleMR: Easy to use

Fits seamlessly into existing workflows, sitting between the scanner and PACS. Images are sent from the scanner and are processed and returned in seconds.

Testimonials

“By utilizing AI-powered imaging technology, we have been able to dramatically increase PET scan efficiency and provide a superior patient experience. The technology allows us to scan a patient four times faster than normal, yet maintain equal image quality, not otherwise impacting workflow.”

Michael Brant-Zawadzki, M.D., F.A.C.R., Senior Physician Executive and the Ron & Sandi Simon Executive Medical Director Endowed Chair of the Pickup Family Neurosciences Institute at Hoag

“One of the most exciting things about deep learning reconstruction is how it redefines the usual negotiation between exam time and image quality. This could lead to significant downstream value for imaging operations and for patient experience.”

Christopher Hess, MD, Chair of the Department of Radiology and Biomedical Imaging at UCSF
