CMOS Imaging Technology

The heart of our technology lies in the advancements to an imaging technology known as Complimentary Metal-Oxide Semiconductor (CMOS). CMOS imagers, because of their low-noise and high-resolution, are challenging and displacing Charge Coupled Devices (CCD’s) that have been the standard imaging platform for the past 35 years. One advantage that CMOS imagers have over CCD devices is the ability to integrate all of the video processing circuitry onto the same silicon chip as the image-gathering photodiodes (pixel array). This allows the entire device to be placed onto a single chip the size of a postage stamp and is known as CMOS single-chip camera, or camera-on-a-chip.

The company capitalized on this technology while taking it one step further by patenting the optimization of the circuitry and camera (sensor) configuration separately.  This separate configuration allows for incorporation into nano-sized medical devices to enable the creation of new products that would not otherwise be feasible.

MIS’s proposed 1000 X 1000 CMOS APS imager (left) is only 2.8 mm diagonal measurement using 1.4nm pixels. For comparison, a standard CMOS camera-on-a-chip device is shown (right side).

Unlike the current industry focus to place the entire CMOS camera on a single chip, our patented technology involves the removal of all of the processing circuitry away from the image plane of a single-chip CMOS camera. This allows the CMOS pixel array to be designed into a very small, nano-sized medical device that is suitable for use in applications that have previously been prohibitive such as medical-surgical products that require a very small imager.  The Company’s technology allows for the video processing circuitry to be placed on a second circuit board and aligned either in a stacked fashion behind the board containing the pixel array (camera), placed several meters “downstream”, or be remote via wireless connection.  In any case, the imager (camera) consists only of the pixel array and timing and control circuitry in order to make the imager package as small as possible.  The small size coupled with low production costs enable disposable vision-assisted endoscopic applications for the first time. Our CMOS imagers can be produced on standard semiconductor production lines.

Our platform-enabling and patented CMOS technology allows for a variety of medical applications, such as image-guided pediatric endotracheal intubation tubes, ENT sinus and ear imaging probes, pulmonary and respiratory imaging probes and image-guided surgical hand instruments that may benefit from combining vision with current disposable devices.
