Summary: Vision Elements conceived and built the 3D reconstruction and flow-analysis technology that lets CathWorks' FFRangio System compute fractional flow reserve from standard angiograms during a catheterization, without a pressure wire. The challenge Coronary artery disease is a leading global cause of death. Fractional flow reserve (FFR) measures the pressure drop across a narrowing; values below 0.75–0.80 predict ischemia. Wire-based FFR needs a pressure guidewire, a hy

Summary: A reference sensor and a second coordinate transform let 2D ultrasound slices captured before and after patient movement be registered into one organ map instead of discarded. The challenge Clinicians building a 3D map of an internal organ sweep a handheld ultrasound probe across the body and register each 2D slice into a shared frame using a six-degree-of-freedom electromagnetic navigation system. The navigation system reports positions relative to its own transmitt

Summary: By treating the antenna as a planar circle, Vision Elements replaced two-view stereo matching with a single-image least-squares solve, giving the client a faster proof of concept and more accurate results. The challenge The client maps antenna poles by drone for maintenance and real-estate management; drone surveys cover large or hard-to-reach sites at lower cost and shorter turnaround. They needed each circular antenna's 3D orientation. Standard 3D reconstruction ne
