November 13, 2018 — At the 2018 Radiological Society of North America annual meeting (RSNA 2018), Nov. 25-30 in Chicago, Subtle Medical will showcase SubtlePET, its artificial intelligence (AI)-powered technology. SubtlePET allows hospitals and imaging centers to deliver a faster and safer patient scanning experience, while enhancing exam throughput and provider profitability. The software is currently under U.S. Food and Drug Administration (FDA) 510k review and in pilot use in multiple university hospitals and imaging centers in the U.S. and abroad.
SubtlePET leverages AI to allow hospitals and imaging centers to accelerate positron emission tomography (PET) scan times four-fold or reduce PET radiation dose by up to 75 percent, according to the company.
A second product pending FDA submission is SubtleMRI, which allows imaging centers to significantly accelerate magnetic resonance imaging (MRI) scans. Subtle Medical’s focus on image acquisition and workflow differentiates it from most AI imaging companies, which are focusing on post-processing and computer-aided diagnosis.
Subtle Medical technology utilizes deep learning algorithms that integrate seamlessly with any original equipment manufacturer (OEM) PET and MRI scanners to enhance images during acquisition without any interruption or alteration in the imaging specialists’ workflow. The result is shorter scan duration or less exposure to radiation, which is particularly beneficial for children and those undergoing repeat PET exams.
In March 2018, Subtle Medical received the NVIDIA Inception Award Top Healthcare+AI Startup Globally from among over 3,000 AI contenders. The company was also selected as the first AI+healthcare startup for Bessemer Venture Partner’s Deep Health Seed Program.
Subtle Medical’s core technology was developed at Stanford University. The company has licensed multiple patented technologies invented by the founders at Stanford as well as medical imaging datasets acquired during clinical research at Stanford radiology labs.
At RSNA 2018, Subtle Medical’s co-founders will be participating in research and industry presentations along with other academic collaborators from Stanford. Presentations include:
