Abstract:
The charge-coupled device is a component of the Intraoperative Optical Medical Imaging System (BIDMC ID #681) to capture both a visible light image and a emission wavelength image.
Dr. Frangioni's intraoperative optical imaging system employs a charge-coupled device that captures both a visible light image and an emission wavelength image. The visible light image may be a grayscale image, or may use sensitivity to a number of discrete wavelengths (such as red, green, and blue, or cyan, magenta, and yellow) to generate a full-color image within the visible light spectrum. The emission wavelength may be, for example, a near-infrared, infrared, or any other wavelength above or below the visible light spectrum. In some imaging systems, the emission wavelength may be a narrow band of wavelengths within the visible light spectrum. The charge-coupled devices described herein may be advantageously employed in an integrated, single-camera medical imaging system, as well as any non-medical imaging system that would benefit from simultaneous capture of visible-light wavelength images and emission wavelength images.

Competitive Advantages:
Current CCD systems that combine visible light and an emission wavelength image require at least two separate cameras, imposing additional costs, software complexity and processing overhead to synchronize and superimpose data streams from the two cameras.
