New Paradigm of Medical Imaging
The core WOI technology utilizes recent developments in tiny, inexpensive microelectromechanical (MEMS) rapid scanning optical devices. WOI will produce a portfolio of proprietary optical imaging probes that are customized for various endoscopic imaging applications (e.g., bronchoscopy and laryngoscopy) and imaging-guided intervention and cancer therapeutic treatment monitoring applications (e.g, breast cancer surgery).
WOI's proprietary MEMS scanning mirrors levarage on innovative microactuator designs , the overwhelming superiority to other MEMS mirror make them best suit for biomedical imaging.
Smallest operating voltage < 8 volts;
Largest scanning range of over 60 degree 2-D steering and over 0.5 millimeter depth scan;
Highest fill-factor with over 1-mm optical aperture on less than 2-mm device footprint;
Up to KHz rapid scanning;
Versatile scanning capabilities including 1-D, 2-D, 3-D and full-circumferential (360º) scan;
Simplest and least costly micromachining process;
Hidden actuators allow wire-bonding free assembly.
Integrated with the latest optical imaging techniques such as optical coherence tomography (OCT), confocal microscopy and nonlinear optical microscopy, WOI’s optical imaging systems provide real-time optical “biopsy”, i.e., obtaining in vivo 3-D high-resolution images of tissue without any physical biopsy.
WOI’s high-resolution, high-speed optical “biopsy” endoscopic imaging systems enable physicians to diagnose caner at early stage without performing any risky and often random biopsy as well as allow surgeons to clearly identify cancer margins during surgery to ensure that all but only malign tissue is removed.
WOI probes can also integrate motion sensors to precisely compensate vibration and patient motion while performing image scanning.
A typical WOI system consists of a control/display console with custom imaging software, a pull-back device, and disposable probe.
