Quantitative Angiographic Systems

Artificial Intelligence

Surgeon's can modify aneurysm treatment plans on-the-fly during an active procedure


Our Technology

Our AI-driven software can be used during surgery to detect areas of inadequate blood flow in the brain and predict  efficacy of aneurysm correction six months after embolization.  

The Process

Our system is an interface between the position of the medical imaging device (the c-arm), image acquition parameters, and processing of the angiographic parametric imaging.  The software surveys tissue perfusion in automatically placed regions of interest after each angiogram, compares it to baseline, and detects the location of ischemia with a 90% probability for accurate diagnosis. QAS.AI software has been trained on thousands of patient data. 


In only 15ms, QAS.AI modules can accurately locate the diseased lesion and predict treatment outcome.    

Minimal disruption to clinical workflow while providing feedback in seconds

If a future occlusion is predicted, the interventionalist can decide if the treatment should be modified 

Future Directions

Development of additional angiographic based software to assess other flow-related pathologies: intracanial
