Sleep Apnea Detection System
Technology Overview OHSU has developed a non-obtrusive system to monitor and diagnose sleep apnea and hypopnea through the use of load cells installed in the supports of a patient’s bed. The load cells continuously and independently measure the weight supported by each leg of the bed, and are sensitive enough to pick up small fluctuations in weight...

Novel Fluorescent Dyes for In Vivo Nerve-Specific Imaging
Technology SummaryResearchers at Oregon Health & Science University have developed novel, small molecule near infrared (NIR) nerve-specific fluorophores for diagnostic use in fluorescence-guided surgery. The fluorophores can be administered directly to the surgical site or intravenously for the precise visualization of nerves during surgical procedures,...

Contrast-Enhanced Magnetic Resonance Imaging for Detection and Quantification of Fibrosis in Human Myocardium
Technology OverviewMyocardial fibrosis is a morphologic change common to multiple cardiac disease conditions. In addition to replacement (scar) fibrosis, there is increasing recognition of interstitial (reactive) fibrosis acting as an important player in structural remodeling of the diseased heart, as well as the genesis of fatal arrhythmia leading...

Diagnosis of Human Malignances Associated with Activating Mutations of Platelet Derived Growth Factor Receptor Alpha (PDGFRA)
Tyrosine kinases are expressed in many human cancers and are attractive targets for the development of anticancer therapies. Clinical response to these therapies is often correlated with the mutational status of the target. The identification of a particular mutation in a patient’s tumor therefore can be used to identify which patients are most...

Differentiating extravascular from intravascular MRI contrast using T2* and SWI weighted sequences
Non-invasive imaging detection of tumor-associated macrophages in glioblastomaSummaryTracking immune responses in chemotherapy treated glioblastomas is important for interpreting disease progression, but current methods are invasive and require biopsies. OHSU researchers have developed an MRI-based method to detect tumor-associated macrophages to enable...

A fast and robust standard-deviation based method for bulk-motion compensation in phase-based functional OCT
Standard deviation phase compensation for OCTA and Doppler OCTThis invention involves a novel bulk motion compensation method for phase-based functional OCT. The two widely used phase compensation methods are the “average” (AVG) method and the “histogram” (HIST) method, wherein the latter estimates the vessel shadow artifact...
